8 TOP TECHNOLOGY WITHOUT LIMITS Perfect automation for your application Automate your machine or plant with Bachmann so you can be sure that every eventuality is covered. Our automation systems stand out on account of their extraordinary robustness, high performance and open interfaces. The latest and most innovative platform for your requirements. Openness in hardware and software The M1 system operates as a real-time system. Different open-loop and closed-loop control programs are adapted in modules and run simultaneously in a useful multitasking environment. Like the hardware, the software is also modular and can be structured and extended as required following our no limits principle. The controller offers additional reserves for expansions or plant-specific adaptions. Functionality means ready-to-use The modular M1 system offers a wide range of hardware, consisting of over 200 devices and modules. This system contains a large number of configurable function blocks for all necessary machine functions, such as visualization, networking, closed-loop control and diagnostics, to provide you with all the basic functions from the start. Here we place great importance in ensuring that all tools are developed according to international standards, and can also be integrated and parameterized flexibly. Compatibility brings investment protection What happens if the performance of the selected CPU is no longer sufficient to load new functions onto a plant in the course of a machine update, or if technology requires the new version of a module to be used? At Bachmann the answer is: NOTHING no problem. Thanks to the abstraction of the customer application from the hardware used and the strict adherence to 100 % compatibility in new developments, the situations described are not a problem for a Bachmann controller and are provided for as standard features. 8

9 industry.application Hardware concept (example) Scalable and open In order to reduce complexity and maximize ease of maintenance, all components of the M1 controller system are consistently developed as part of a modular system. In this way, optimum scalability is ensured for a wide range of requirements. The M1 system perfectly combines the openness of a PC-based controller with the reliability of industrial hardware platforms. A state-of-the-art system architecture designed for consistent networking capability enables you to integrate it easily in the environment of the controller and plant peripherals.

10 INTEGRATED CONTROLLER TECHNOLOGY Advanced flexibility Bachmann controller modules are specially developed for machine and system building. With them we can implement extensive functions compactly and economically for you in the M1 controller system. Maximum flexibility and a comprehensive range of functions optimize the efficiency of your plant. Scalable performance CPUs that match each application With a performance range up to purely passively-cooled 1.2 GHz processors, individual requirements can be met easily with a wide range of multifunctional CPUs based on industrial processors. The application starts with standard applications (MX213 with integrated power supply unit) and goes right through to the most demanding applications with the greatest requirements in terms of performance (MH212/S with Gigabit Ethernet). The CPUs are provided with two Ethernet interfaces, RS232 and USB as standard. Networking capability and the connection of USB devices do not therefore involve any additional costs. A large memory with CFA and CFast technology is provided for storing all data safely. In the event of a power failure, critical data is stored in battery-backed non-volatile data memories (NVRAM). The Bachmann M1 controller uses this to also process complex applications with maximum speed and precision.

11 industry.application Multifunction cards GIO and AIO I/O modules The AIO/GIO200 series offers an impressively wide range of functions, thus making the use of expensive additional modules in most places unnecessary. All channels of the universal I/O module can either be configured as analog or digital inputs or outputs, as counters or for temperature and resistance measurement. Depending on the function selected, a channel can be assigned up to two functions (mixed mode operation). The digital outputs also come with a special feature: Each channel provides an output current of 100 ma and can also be configured as a push-pull driver, in addition to the ground or positive switching: A simple configuration can thus enable a free digital output to be used, for example, to feed a 20mA sensor. Cable breaks and the power supply can thus also be monitored without any time consuming integration, without an additional module and without further costs. Maximum flexibility and efficiency The AIO/GIO200 series enables changes to a project to be implemented more simply at short notice. The search for alternative modules becomes unnecessary and plant conversions, parts list modifications, reprogramming and the necessary tests become a thing of the past with the new modules. You only need to adjust the settings in the configurator and that's it. Another benefit: The simpler management of spare parts only one module needs to be kept in stock instead of a host of different variants. AIO/GIO200 features Digital and analog inputs/outputs Up to 16/32 channels Temperature sensors (PT100/200/500/1000 as 2/3/4-wire circuits) Thermocouples (J, K, T, N, E, R, S, B) Resistance measuring Overload-proof, short-circuitproof and protected against external voltage Voltage and current inputs/ outputs (± 20 ma, 0(4) 20 ma, ±1 V, ±10 V) Highly compact digital I/O modules The DIO200 digital input/output modules in the Bachmann M1 system are enjoying enormous popularity. The version with the largest number of channels, the DIO280, is a highly flexible module with 32 digital inputs and 32 digital outputs, as well as 16 digital channels that can be configured as either inputs or outputs. Eight of the inputs can be event-driven. They can also be configured so that they trigger the integrated counters directly: Four 32-bit counters can be set as up counters (track A) or as up and down counters (track A and B) in different modes. Thanks to the high counter frequency of up to 20 khz, many applications with a 24V signal can also be implemented easily without the need for a separate counter module. With up to 80 digital I/Os on a width of 110 mm, optimum use is made of the available mounting space, thus enabling the implementation of highly compact applications. DIO200 features 16, 32, 48, 64 or 80 digital inputs/outputs 16 channels software configurable as input or output Interrupt-enabled inputs Cable break and short-circuit detection Integrated counter and PWM function 11

12 HUMAN MACHINE INTERFACE Visualization of the Future In the 40-year history of our company we have been actively engaged in the development of the Human Machine Interface for over twenty years. Always targeting the specific requirements of our business partners and the machine building sector, Bachmann offers a complete range of visualization systems in different performance classes and for different application fields. Low-range/mid-range and high-range product families Different applications require different solutions. Bachmann offers here three basic performance classes of visualization devices. The operator terminals of the OT200 series, which are available with different resolutions and interfaces, offer the entry level into the ideally web-based visualization. These impressive devices come in a compact design and with a wide range of interfaces. The mid-range OT1300 series covers the mainstream requirements of industrial applications and machine building. This range is described below in further detail. When it comes to modularity and the creation of individual versions, the industrial PCs of the 1400 series are the ideal choice. As a remote unit for decentralized visualization, as a control cabinet unit or as a compact device with PCIe slots and an RAID system, the series can cover all non-standard applications. It is also scalable in terms of display size and performance. Latest panel technology of the OT1300 series Besides offering the latest Intel CPUs, the new variants of the OT1300 series also enable the interfaces and the memory media to be expanded. As with all Bachmann products, the two GBit Ethernet interfaces offer the possibility of connecting the controller system and a DCS at the same time via different networks. A new serial interface is also provided for connecting proven peripheral devices. The four USB interfaces are still provided for connecting removable memories, operator devices, camera systems and similar devices. The trend in machine and plant visualization towards complex graphics interfaces combined with a high volume of data can also require the possibility of safe data storage on the device. In addition to the high performance and externally removable CFast card technology, a 2.5" mass storage memory can also be integrated in the device. The actual mass memory, as well as features such as 24/7 operation, 12

13 industry.application Overview of HMIs / IPCs increased shock and vibration protection or faster write speeds must be selected specifically for the individual application. To meet this requirement, a wide range of HDD and SSD products are available for selection. Configuration / commissioning / diagnostics As with all Bachmann electronic products, the HMIs and industrial PCs are fully integrated in the SolutionCenter and can be configured easily and conveniently. The devices are also provided with an onboard web-based configuration software that allows all settings to be carried out on the device itself or via web access. The USB recovery sticks round off the range of features, allowing the user to back up the factory settings and load them if required. This reduces the effort required for manual settings by the service technicians. the front plate and thus give the machine visualization corporate identity. For us, plug & play also means the ability to customize software installations at the factory so that the device just has to be fitted and switched on. The standard temperature range provided from 0 to 60 C ensures safe operation in virtually any application. A high level of reliability (ensured through 100 % testing at full load over the entire temperature range), optimum EMC values, temperature compatibility, as well as shock and vibration resistance are just as much part of the standard system features as easy maintenance and long product life cycles. Just as the customer wishes The HMI is the face of the machine and is therefore often at the center of all design questions. mann electronic ectronic covers this Bach- issue extensively and offers the possibility sibility to customize OT1300 features TFT from 10.4 to 19 AMD DualCore to Intel Core i7 3rd generation 2x Ethernet, 1x RS232, 4x USB 2.0 CFast card or SSD as application memory Linux embedded, Windows 7 embedded SolutionCenter integration 13

14 HMI OF THE FUTURE M1 webmi pro The widespread global use of Internet-enabled mobile devices has taken place at breathtaking speed. Their simple and intuitive operation is impressive. Internet and software applications no longer have a fixed location but can be used from anywhere in the world. With M1 webmi pro, Bachmann electronic is impressively demonstrating its technology leadership: Each M1 controller is turned into the central server for fixed or mobile HMI devices. Benefits of M1 webmipro at a glance: Value displays with high refresh rate Any browser-based device becomes an HMI Operation and visualization when and where you need it Loss-free scaling to all screen sizes As safe as Internet banking (HTTPS) Short refresh in the browser instead of time-consuming software rollouts Use of the application by different devices (smartphone, tablet or stationary HMI devices) Integration in higher-level SCADA applications Engineering and maintenance an important cost factor Plants are becoming increasingly more complex with ever increasing requirements. This also naturally increases the effort required for engineering and maintenance as well. It is often not only necessary to allow for local visualization in the field, but also for the connection to a control center, a separate visualization for teleservice and sometimes also solutions for mobile terminal devices. Often each requirement here has to be implemented with separate applications. With many visualization products, the handling of different terminal devices and screen resolutions is also not possible. Pure web visualization for the Bachmann M1 Bachmann electronic is now launching a powerful product for pure web visualizations on the market called M1 webmi pro. A slim-line web server that is directly installed on the M1 controller enables the connection of any visualization devices such as smartphones but also powerful operator terminals. Provided the necessary authorizations are in place, the application can now be accessed from anywhere in the world. Thanks to M1 webmi pro all the important information can be shown in a single view and with stunning definition. Perfect graphic results can be achieved on any visualization page without any losses in quality when scaling and zooming. This is thanks to the extraordinary benefits of HTML5 and SVG (scalable vector graphics), the basis for all graphic objects. State-of-the-art project engineering and simple delivery The atvise builder engineering tool is used for drawing process pictures, configuring animations and events as well as for other settings. A number of ready-made graphic objects and layouts, as well as the flexible reuse of pages using parameter transfers make it possible to create visualizations efficiently. Integrated editors even allow the drawing of new SVG graphic objects or the creation of additional functions with user-defined Java scripts. Once the visualization is completed, this is transferred to the web server via FTP with just a single click. This makes the delivery of visualizations to large and distributed installations child's play. Time-consuming software installations to all HMI devices involved become completely unnecessary. The latest version of the application is always shown as soon as a client connects with the central web server or reloads the web page. Special installations or a restart of the HMI devices are no longer necessary. All operator units are thus automatically brought 14

15 industry.application Client Client Client Client Ethernet/Internet PLC M1 webmi pro The web server on the Bachmann M1 forms the visualization center, any clients can access it with a web browser, regardless of time and place. up-to-date without any interruption and irrespective of time and place. Increased efficiency included The development of web technologies had to allow from the outset for a wide range of different terminal devices, since different screen sizes and resolutions are normally used. Visualization design in M1 webmi pro is much easier however, since only a single application has to be created for all devices. If the visualization solution is also implemented directly on the controller, the configuration of the relevant data interfaces is also unnecessary: The variables can be accessed directly, an OPC server or any proprietary protocols become obsolete. Ultimately, this kind of web solution not only means more efficiency in engineering but also a real increase in cost efficiency. SCADA with 64-bit power The increasing complexity and the constantly rising level of automation in a wide range of different installations require future-oriented technologies for monitoring and controlling processes effectively. SCADA systems make a key contribution here and ensure a high level of safety. This is especially the case if they offer, like the atvise product line, operation that is not restricted to a particular location or device. The atvise scada control station combines the latest web technology with a high performance client-server architecture. While user interfaces can be displayed in web browsers without any installation required, central functions such as process connection, historization, alarm signaling can be run in highly efficient server structures. The full utilization of the internal data structures of the latest processors increases system efficiency. At the same time, the 64-bit data width enables the utilization of considerably more main memory which ultimately allows larger projects with more process variables (nodes). Released operating systems include Windows XP SP3, Windows 7 (32-bit and 64-bit), Windows 8 (32-bit and 64-bit), Windows Server 2008 and Windows Embedded Standard 7. Besides other minor improvements, version 2.5 also contains functions for filling in the process history (value archive) at a later time, such as when the transfer of only temporarily connected process connections is blocked.

18 SCOPE Data recorder with outstanding functions for the M1 controller The Bachmann SolutionCenter meets all the requirements of the automation technician in the engineering process. The operator interface is completely adapted to your personal requirements and offers you highly efficient tools that simplify your work and thus save time and costs. Bachmann's software oscilloscope offers an efficient tool that helps the user one decisive step further in the diagnosis and analysis of his automation project. Modern machines and plants are mostly characterized by a high level of complexity. Commissioning, troubleshooting and maintenance therefore present a major challenge. Actual values and the tracing of process data and parameters over time are of key importance here. This requires tools that supply this data without any restriction and support the technician in his work with more detailed analyses. Data logging at high speed The core of Scope 3.0 is a powerful data logger: It offers an outstanding scan rate that can be selected in a range from 100 microseconds to 60 minutes. Thanks to the multi-tasking architecture of the M1 automation system, several data series can be logged in parallel and with different scan rates. Interfaces for several application programs increase the functionality of the product. Database with selective access Data archiving and data provision is a central aspect for an autonomously functioning data recorder. With Scope 3.0 a database archives all data in the background and offers selective access to it. Archive size and archiving intervals can be set to individual requirements. All data from the online buffer and also from the database is available at the same interface. Data analysis of complex interrelationships A powerful software oscilloscope can only be an effective tool if it has an efficient solution for viewing and preparing the data. This enables you to understand interrelationships more simply and carry out analyses faster. Scope 3.0 offers you an optimized tool: A simple click on the data recorder of an M1 controller enables data to be displayed immediately and makes it ready for analysis. The configurations can be 18

19 industry.application Scope Tool High precision: The relationships of various process variables over time are analyzed and the exact values read out with the measuring cursor. M1 Scope Application Data recorder Data archive managed in the work space and the storage of the logged data can be structured. Frequently used graph functions, such as measuring cursor, zooming, color adaptions are supplemented with important new functions curve recalculation, the graphical comparison of logged data or the fast Fourier transform function are now directly available for the user. The user can also implement his own calculation methods or export formats. Simplified maintenance and service Previously in the event of a fault, a connection to the relevant machine or plant often had to be established in order to fetch the relevant data for analysis. In certain cases, work directly on site was then unavoidable. With Scope 3.0 this is no longer necessary. The occurrence of a fault automatically initiates the logging of the relevant data. Data generated around this time range can be incorporated easily with the pre-trigger and post-trigger functions. After logging has been completed, a file with all the relevant data of the event is generated on the controller and automatically sent to the service technician by a key benefit for efficient support. One product, many possibilities Scope 3.0 is perfectly suited for the convenient analysis of processes and troubleshooting during engineering, commissioning and the maintenance of machines and plants. Thanks to the wide range of functions and interfaces to the application programs it can also be used as a production data archive. In short: Bachmann's new Scope 3.0 offers an impressive performance due to its simple operation and wide range of uses. 19

20 KEEPING IN SYNCHRONOUS MOTION Motion Control Bachmann customers and partners can now make use of proven and highly optimized software controllers for different applications. Startup and diagnostics tools designed by experienced users and with graphical user interface simplify use. The portfolio of ready-touse components ranges from the simple motion control of several axes to CNC and virtual shaft controllers, up to special modules for sophisticated pressure or temperature applications. Drive Middleware standardized drive control A technology of Bachmann's M1 automation system makes it possible for drive controllers to be selected irrespective of drive type whilst still maintaining an intuitive and convenient PLC connection. Based on the IEC standard, an open and universal interface to the drive engineering called Drive Middleware is implemented in the Bachmann M1 automation system. This handles the transfer of the logical drive with a manufacturer independent standardized drive profile to the actual physical drive. The standardized profile standardizes the user-specific status machines, error routines, referencing methods and motion profiles by defining a logical drive based on PLCopen Motion. All standard fieldbuses (CANopen, EtherCAT, SERCOS, PROFINET etc.) are supported. The Drive Middleware can be extended with additional fieldbuses, thus offering the possibility to add manufacturer specific parameters to the interface description. Dynamic positioning In order to position coordinated single axes or complex master slave systems (gantry axes) the highly efficient M-SMC Soft Motion Controller is available in the form of an easy-to-configure function module. Infinitely variable acceleration profiles enable jerk and machine dynamics to be adapted optimally to the requirements at hand. The integrated Move-in-Move function not only enables motion parameters to be changed online during operation but also the target position without having to stop the axis. Shaft The M-SHAFT motion function module simplifies the mapping of several synchronized positioning sequences to a virtual master axis. Up 20

Graphical or table-based settings for the position profiles, as well as the choice of different acceleration types provide a solid basis for complex machine sequences. Alternatively, the Table Interpreter can use individual support points to calculate an optimum positioning profile for maximum machine throughput. Path movements to DIN66025 Machining systems using servo electric axes can be implemented in many cases directly from the design data. The geometry and machining definitions in accordance with DIN/ ISO66025 have become widely established as a popular exchange format in computer-aided manufacturing (CAM). M-CNC provides a readyto-use motion controller to convert this information into synchronized multiple axis motion. 21

22 ACCESS RIGHTS & SECURITY Access control and access logging The need for greater security on machines and plants is continuously increasing since any unauthorized manipulation of processes can result in serious damage. Furthermore, the complete logging of interventions is even a statutory requirement in some sectors. The definition and management of access rights in the M1 automation system have now been made even easier. Plants are controlled locally at the device, via mobile devices or from a control station located at a distance. Operators, plant owners, process engineers, service technicians and many other plant users have completely different perspectives, interests and needs with regard to data access. The principal aim of rights management is to assign each user with the correct read and write access to process variables as well as to the file system of the controller. At the same time, data and parameters must be prevented at all costs from being manipulated by unauthorized persons or even accidentally. The security functions in the SolutionCenter were therefore provided with even more convenient configuration options. Group formation Access rights were previously implemented using levels: The higher the level, the more rights the user had. However this can no longer fully cover the wide range of different applications. Part 8 of the IEC62351 standard (Data and Communication Security) therefore describes a role-based access control : Users are assigned to a group such as Viewer, Operator, Engineer or Installer, depending on their role. The configuration of user rights was therefore fully overhauled in the SolutionCenter with this in mind, with groups and their system rights as a prime objective. Users are now no longer created with completely different rights but are assigned to groups to inherit the associated rights. Some roles are predefined, whilst others can be defined by the user as required. The existing settings are naturally also available for existing configurations. Detailed rights assignment to files In a second step, files or file paths are assigned to the individual groups. This enables read and write authorizations to be issued at the drive level (USB stick, CF card, etc.), to directories, right down to individual files. Thanks to an intelligent inheritance concept this mostly only requires a few entries. and to variables SVI variables make process values from the application available to the outside world. Actual values (temperatures, speeds, operating states etc.) should already be marked here as read only in the variable declaration. It makes no sense anyway to set these values from outside, regardless of the user role. However, it is now possible to assign rights as required: Individual read and write authoriza- 22

23 industry.application Rights control by group: The individual users are assigned to these groups and inherit the associated rights. tions can now be assigned to each individual process variable depending on the group to which the user belongs. As with file rights, the inheritance concept is also used here. However, the hierarchy is not structured according to file paths but according to software modules and instances of function blocks. It is also possible to define input limits for selected variables. Testing on the controller When the user logs into the controller, the Login Checker determines the Group and Level attributes of the user and from then on takes this into account in all activities. Whether the user wishes to make use of the machine visualization, the SolutionCenter engineering tool or a standard communication such as OPC UA therefore does not matter at all. The rights control is always active, regardless of the tool used. One version for everyone Groups, users and their access rights are defined completely independently of the software development and can be finalized before the delivery of the system or even not until commissioning. This means that any customization of rights does not require the operational control software to be recompiled, tested and archived in different versions: Always the same software version can be delivered. For plant builders this means that the solution implemented in the SolutionCenter can therefore offer yet another key benefit. FDA 21 CFR Part 11 The automation products and solutions of Bachmann can implement requirements in accordance with FDA 21 CFR Part 11, such as for tablet presses. Security facts Security log If required, all activities from outside are permanently recorded in the security log: For example, if a SCADA or ERP system write accesses a variable via OPC UA, information such as the user name, time or original and new values are stored. All logins and interventions are likewise visible in an online monitor in the SolutionCenter. SSL encryption Dynamic password generation Access protection at variable level Memory protection Access logger in the operating system 23

24 SAFETY WITHOUT COMPROMISE Safety Control Whether for a simple emergency-stop function at the machine console or distributed safety technology with optical sensors, redundant cables and the control of emergency-stop categories in modern servos: The SLC284 programmable safety module and the safety-related digital I/O modules from Bachmann offer a safety solution that is fully integrated in the M1 automation system, and which can be expanded for individual requirements in compliance with all safety standards (PLe / SIL3 / Cat 4). The safety modules, designed throughout as dual-channel modules, enable input and output channels to be connected redundantly in pairs. The modules can also be operated remotely in the network without a configuration. The configuration and programming of the safety functions are integrated in the SolutionCenter all-in-one engineering tool, thus enabling standard PLC tasks to be linked seamlessly with the requirements of functional safety. Simply safe Regardless of the automation field in which you wish to develop, our innovative automation solutions provide you with a host of possibilities. Controllers with integrated safety as well as operating devices and drives are all perfectly matched, and allow open communication. Man at the center With this in mind, fast reaction times, intuitive operation and extensive diagnostics options are key priorities in Bachmann safety solutions. The user obtains an optimum level of safety: Established standards such as ISO13849, EN 62061, EN 61508, PLCopen Safety and IEC are used, and the development of proprietary solutions is consistently avoided. Integrated safety solution Through the possibility of mixing safety and 24

25 industry.application non-safety channels and the availability of all I/Os in the software, double wiring can be avoided, thus considerably reducing costs. Tools for safe application programming Bachmann offers a collection of tools for safety-related application programming to round off the fully integrated programmable safety solution. The Safety Developer is a central interface between the programmer, user and hardware, and provides support together with other elements of the SolutionCenter for an economical implementation and the high safety standard specified by the hardware. Creating user-defined templates with simple Copy & Paste A central strength of implementing safety concepts in the software compared to the use of wired solutions is the fact that once programming is completed, they can be kept in a secure archive after successful verification and validation and used in series. Furthermore, reusable sections can be taken out in easy steps in the Safety editor and handled as user-specific templates. This improves management and reduces the possibility of errors, whilst saving time for future programming projects at the same time. Configuration, project management and programming for the most demanding requirements The safety modules are fully integrated in the M1 system and are therefore also integrated in the SolutionCenter all-in-one development environment. As with all system components, online and offline configuration, firmware updates and extensive monitoring, in tables and also using the Scope functionality, are carried out in the Device Manager. The engineering environment also includes the user-defined project management function, if required also with server-based version control. This enables several developers to operate on the same project at the same time, and test phases as well as release procedures become simpler. It also enables the normative requirements for the comprehensive documentation of safety-related application software to be implicitly fulfilled as an additional benefit. Safety Developer the safe choice The Safety Developer supports programmers in many ways. Safety applications can be programmed, visualized and maintained more safely and quickly with this toolbox. Safety-relevant accesses are documented automatically, and the intelligent evaluation of system status information supports the user in troubleshooting. In other words, the Safety Developer provides greater safety and increases the availability of the machine. Controllers with integrated safety Safety Control. The actual programming of the safety applications is carried out in the FBD editor, supported by an extensive library of certified function blocks. More than forty function blocks fully tested in accordance with IEC and PLCopen Safety form the basis for implementing applications of different complexity. Useful functions such as the safety evaluation of paths, user-defined help and error messages, and not least the intuitive addition of system variables using drag & drop simplify routine programming tasks and thus increase safety.

26 INTEGRATED POWER MEASUREMENT Consumption up to power quality A safe and reliable power supply is the basis for any successful production process. Ensuring this in a drastically changing energy climate is a growing challenge. Through the use of high quality grid measuring modules critical energy performance indicators can be measured in real-time and monitored. This consequently prevents the development of load peaks, reduces reactive power and ensures an uninterrupted power supply. Energy consumption measurement Statistical evaluations are often carried out by a higher-level power management system and are also used for recording energy efficiency. Power management systems such as in accordance with ISO are becoming increasingly more important. These use so-called energy performance indicators to assess energy efficiency so that it can be continuously improved through suitable measures. However, statistical evaluations can also be used to measure load curves in order to determine the average consumption and base load. The Bachmann grid measuring modules offer several statistical performance indicators in relation to the measured grid variables. These include min./max. values, energy meters, total harmonic distortion (THD), etc. These statistical grid variables can be accessed simply via the so-called Service Variable Interface or a PLC library, and can be forwarded cyclically via FTP or to higher-level power management systems. Keeping a close eye on the power supply With all the new possibilities offered by power supply 2.0 no compromises are allowed when it comes to power quality. In industry, supply security has a direct effect on productivity. The extent of this and the countermeasures that can be implemented primarily depends on the production process. Examples: Production processes with long startup times With plants requiring long startup times, a temporary disconnection (< 1 min) of the power supply may result in protracted new startups for the production process. With these kinds of plants, it should be ensured that operation is as robust as possible, i.e. in the event of a fault the power supply should be switched with as little interruption as possible. 26

These kinds of short interruptions can often be caused by the switching actions of the transmission network operator and are hardly noticed in normal operation. Trust is good, control is better. This maxim also applies when the power supply is involved. Momentary power interruptions or harmonic contamination can have a negative effect on the equipment of a production plant. This leads all too often to the utility company and the consumer blaming each other without a solution being found in good time. In order to deal with these kinds of problems, it is above all necessary to log the relevant events and provide absolutely clear documentation. Only if the actual situation is unambiguous is it possible to work on a solution. Sequence of event lists The monitoring of several key parameters can be configured ergonomically via input screens. If an event occurs, this is logged retentively with an exact time stamp. This log can then be exported simply as a.csv file. Fault recorder If there is an anomaly, the scan values are recorded in real time with a resolution of up to 100 µs for up to four seconds. This data is then available for further analysis in the Comtrade file format. This format is then also used by signal generators which read in the exported file and can then generate the same signals from them as were stored on the device at the time of the fault. This increases competitiveness through the more efficient use of energy. On the other hand, the complexity of the energy infrastructure is increased. As an experienced partner, Bachmann can offer its services to meet these new challenges safely and reliably. Bachmann grid measuring modules therefore include the following integrated features which provide considerable help in the documentation of the power supply quality: 27

28 MODEL-BASED DEVELOPMENT M-Target for Simulink The challenges placed on the automation in and around machines and plants are constantly increasing. The increasing size of plants and the introduction of new technologies have also increased the complexity of operational control programs. New development techniques for creating these programs are needed in order to minimize the development effort required on the one hand, and to bring out technically mature and highly available plants on the other. The increasing complexity and size of plants also considerably changes the development process. If simple analytical advance calculations can no longer describe or predict the response of a system, practical experimentation is the only solution. Models and prototypes are used to obtain findings and develop a solution. However, what happens if the production of these pilot systems is too expensive, offers only restricted use, or if practical tests are simply too dangerous? Today s answer is: Digital simulation. The actual systems are simulated in a computer program in the form of a simulation model. Irrespective of the type of modeling, mathematical interrelationships are used to describe the response of the system. If these simulation models are recalculated with different environmental conditions and parameters, this corresponds to a virtual prototype test. Safe, affordable, repeatable as required and fully automated. M-Target for Simulink enables the simple use of computer-aided simulation, taking the actual automation solution into account. 28

29 industry.application Direct download to the M1 controller Simulation Solutions from the computer model Quality and efficiency The use of high quality algorithms increases product quality and plant yields. The increasing efficiency of plants can be achieved through the use of new closed-loop control and optimization concepts. Solutions which are developed with the help of M-Target for Simulink can fully demonstrate their strengths in these disciplines. The MATLAB / Simulink tool from MathWorks is well-established on the market. It offers support when creating a simulation model of the subcomponent to be automated. For this, the standard modeling methods provided by MATLAB can be used. Alternatively, it is also possible to use the interfaces to several commonly available domain-specific simulation programs in order to utilize part simulations that have already been created. The algorithms required for automation are then created directly in the simulation environment and their functional suitability checked. Automatic code generation As soon as the simulation has produced satisfactory results, i.e. when no weaknesses in the requirements specification and no algorithm errors can be identified, the compilation from the simulation language into executable code for the M1 controller is executed at the push of a button. This is machine compiled by the system, thus eliminating the possibility of any random errors. After code generation, the executable automation program can then be tested immediately on a hardware-in-the-loop test rig equipped with actual controller components or on the actual plant. Cost efficiency Getting to market faster with the better solution this is the basic tenet of our global economy. This is where M-Target for Simulink with the M1 automation system from Bachmann offers considerable help. Calculable investments that are also inexpensive compared to their benefits pay for themselves quickly. The customer-friendly license model of M-Target for Simulink does not involve any unit-based purchase of licenses and thus has no negative effect on product profitability. Highlights of M-Target for Simulink Development of automation algorithms (open-loop and closed-loop) directly in MATLAB / Simulink Automatic code generation and transfer to the M1 controller Online communication between the Simulink development environment and the PLC program for ergonomic parameterization and diagnostics Integrated simulation modes for the I/O modules used in the application Integrated interfaces to visualization systems and other PLC systems Integrated interfaces to automation programs created in conventional programming languages (IEC , C/C++) Support for hardware-inthe-loop systems (HIL) 29

30 Production Quality NETWORKING IN REAL TIME Communication Efficient automation systems are based on open and standardized communication. Particularly when the devices and systems of different vendors have to be integrated into an effective overall concept, or when operators put additional plant sections into operation over the course of time, seamless communication must be ensured. The networking of machines and plant sections as well as the associated data exchange are gaining increasing importance. Individual machines can no longer be regarded as island solutions but are provided with information from a higher-level control system or ERP/MES system with information and settings and in turn have to pass on the accumulated data. Although Ethernet-based communication protocols have basically become well-established, a large number of variants have also been developed in recent years. With its communication packages Bachmann electronic is already meeting today's requirements in terms of products, making it the ideal partner also for networking needs. OPC DA and UA tested standards The Bachmann M1 OPC Enterprise Server provides you with a PC-compatible software interface in accordance with the OPC standard. 1.0, ERP / MES system Controller level Maintenance Logicstics Cell computer 2.04, 2.05 and 3.0 specifications are supported in order ensure comprehensive coverage of a wide range of clients (e.g. SCADA systems, production data acquisition, visualization systems). The OPC server guarantees genuine conformity and thus straightforward use without any problems. This has been confirmed through various certifications and interoperability tests. A large number of our customers can also confirm the capability and stability of the system. Field level As well as the products for the OPC standard and OPC Enterprise Server (Classic OPC stan- 30

31 industry.application dard to DA 3.05), Bachmann is extending its portfolio in the area of OPC products. The new OPC UA server runs on the controller with the VxWorks real-time operating system, thus making the previously required additional Windows PC unnecessary. This increases the availability of data as PCs with Windows are often less reliable than the highly available M1 controller. The operation of the server directly on the controller CPU enables the direct connection to process data and thus the real-time recording of value changes with an exact time stamp. A clear improvement compared to OPC Classic is also available in the field of IT security: The definition of the new standard was thoroughly based on the latest technologies for network security. Client and server identify themselves with unforgeable TLS certificates so that the communication partner can be unambiguously recognized by both parties. If user authorizations were assigned for the process variables of the M1 controller, these are accepted by the UA server without any further configuration steps necessary. The visualization client therefore also only has read and/ or write authorizations to those process values that were intentionally made available for it. Naturally it is also still possible to carry out an anonymous login without user identification for applications in a self-contained network, such as in an assembly line. bluecom the real-time transfer protocol Bachmann offers a real-time capable communication protocol for synchronous data exchange in networks. Based on Ethernet mechanisms, bluecom is designed for high-speed, real-time operation in which for example 250 stations can exchange data packets of 250 bytes in only 20 ms. This therefore provides you with a technology that can implement the closed-loop and open-loop control of entire energy grids. In coexistence with standard protocols such as OPC, IEC61400, closed-loop control and data communication can run simultaneously on the same medium. Bluecom makes it possible to create variable topologies, and the integrated control mechanisms enable single stations right through to entire network segments to be added or removed in a controlled manner without any interruptions.

34 HIGH SPEED FOR ULTRATHIN FOILS Automation of high-performance rolling mills Achenbach is a high-tech mechanical engineering company that belongs to the most important manufacturers of rolling mills for non-ferrous metals. For many years, the company has relied on the Bachmann M1 automation system to provide the control technology for its systems. Beside its performance, Achenbach has been convinced by the reliability and openness of the M1 system. Achenbach Buschhütten is a worldwide-recognized, independent and owner-managed family-owned company that can look back on an over 555-year tradition. The company headquartered in Kreuztal (Germany) was founded in 1452 as a hammer mill, later became an iron foundry and, since 1888, a builder of rolling mills. Achenbach began to work early with the light metal aluminum and built the first aluminum rolling mill as early as Fifteen years later, it was again Achenbach that invented coiling and uncoiling and so laid the foundation for today s strip and foil rolling mill technology. Today, the company is the world market leader and is considered the specialist for aluminum, fine strip and foil rolling mills as well as for rolling mill automation. The company s main attention is focused on the perfect integration of mechanics, hydraulics and intelligent control technology with the goal of achieving maximum productivity of its rolling mills. The performance of the automation system thereby takes on a central role. "The openness and capability of the M1 system help us stand out from our competitors in terms of the functionality and reliability of our systems," says Roger Feist, Department Head for Function Technology at Achenbach Buschhütten GmbH. Modular measurement and control system For some years, the Bachmann M1 system has been at the heart of the Achenbach OPTIROLL i2 automation system. As a complete system, it integrates the technological control system as well as the process management level of the rolling mills and operates the interfaces to production planning and control. The foundation of the integrated complete system is the powerful basic automation ("Level 0"). This encompasses all sequence controls, pressure and position control circuits as well as the related sensors. The technological control systems ("Level 1") encompass the quality and productivity-determining functions, such as strip-thickness control and strip-evenness control, as well as the guide value control for the drives. The process management level is defined as "Level 2" of the integrated automation system OPTIROLL. This contains all functions needed for process 34

35 industry.application control at the rolling mill. These include in particular, operating and visualization systems, setup computers with databank-based pass schedules and powerful model functions. Data recording with wide ranging reporting possibilities is the basis for quality assurance and process optimization. Openness permits variety Production planning and control is integrated through customer-specific systems into an ERP system ("Level 3") with production planning (PPS) or manufacturing execution systems (MES). "The open interfaces of the M1 automation system offer a wide range of possibilities for seamless integration into the complete system," says Thomas Schmidt, Group Leader for Control Technology at Achenbach. As standard, OPTIROLL i2 provides process data over an OPC interface and receives through this interface the manufacturing instructions for the following metal strip, the coil. "Through trendsetting system characteristics, we offer our customers marked advantages and set standards regarding ease of operation, productivity and reliability," says Thomas Blacksmith, describing the major goals, and is glad that "with the M1 I have a system that is both lean and powerful, and which is able to solve control tasks elegantly and without burdening the system." Thinner than a human hair With an Achenbach rolling mill, aluminum foils of over 2 meters in width can be rolled to a minimum thickness of 6 μm. For technical reasons, in the last rolling pass two layers of foil lying on top of each other run through the roller gap, which is controlled at a constant prespecified pressing force. In contrast, for thicker materials of 300 μm, for example, which can be rolled on the same machine, position control is used. For this, rolls weighing a ton must be positioned with a precision of 1 μm and controlled in a highly dynamically way. Not an easy task with a foil transport speed of over 2,200 m/min faster than people can drive on most European expressways.» We've found an outstanding partner in Bachmann. «Roger Feist, Department Head of Function Technology Ingenious layout of sensors: Achenbach technician Tim Schuhmacher calibrates an evenness measuring roll 35

36 Synonym for high technology and quality: Foil rolling mill from Achenbach Buschhütten High speed requires high performance The quality of the rolled product and the productivity of the system depend largely on the precision and efficiency of the measuring technology used, which Thomas Schmidt calls "one of the key functions in the production process". For example, the better the evenness to be achieved in the roller product can be set, the faster the strips or foils can be transported through the rollers. The evenness of the rolled strip or foil is measured with a special evenness measuring roller from Achenbach. The tension distribution of the material, which can be taken as a reliable measure for the evenness, is recorded with high resolution over the entire width of the material. 200,000 measurement values per second In an ingenious arrangement on various angle positions along the measuring roller, up to 70 piezoelectric sensors record the smallest tension differences and pass these measurement values on to the M1. "The data volume generated with high strip speeds is enormous, and the control circuits must really be extremely fast," says the roller mill technology specialist Schmidt as he explains the demands on the control system. In numbers: "The measuring rollers rotate at up to 3,000 revolutions per minute and with each revolution pass on to the computer over 4,000 measurement values with 16-bit resolution." This means that over 3 megabits of data per second must be evaluated to properly control the production process with a multitude of actuators. Bachmann electronic has developed a special interface for Achenbach that seamlessly integrates the proven measurement data recording into the control system in real time. Controllable rollers with changeable mechanical dimensions (position, bending, camber) serve as active actuators. For thin strips and foils, the distribution of coolant along the rollers is especially important. Several hundred nozzles individually regulated by the M1 controller and movable along the roller axis distribute the coolant onto the rollers in the "WIN-SprayS " zone cooling system patented by Achenbach. "And so we achieve extraordinary evenness on the strip or foil," adds Thomas Schmidt. 36

37 industry.application Flexibility is everything Besides productivity and quality, flexibility is the third factor that determines the usefulness of a rolling mill. The user would like to switch over the system to different materials and strip thicknesses relatively quickly and as simply as possible. Here, the capability of human machine interface and SCADA (Supervisory Control and Data Acquisition) applications are of decisive importance. Here Thomas Schmidt welcomes the openness of the M1 system: "We can use global standards and, with the problem-free integration of C# applications, which run in the Microsoft.NETframework we are largely platform-independent and so not bound to proprietary solutions." Future-oriented solutions "Technology for future concepts" is the philosophy that guides all thinking and acting at Achenbach. The company has the technological knowledge to carry out its customers future ideas for production of first-class strips and foils out of metals such as aluminum, copper, zinc and their alloys using customized system technology. Roger Feist is convinced: "With OPTIROLL i2 and the M1 system as its core, we re very well prepared for the constant further development of our rolling mill technology." Availability decisively determines productivity The availability of a system determines its productivity to a large extent. This means that the failure rate and possible downtimes must both be minimized. And so for Achenbach, the mechanical and electrical design were significant selection criterias for the automation system. "In terms of our operational conditions, we have identified in particular thermal and mechanical influences, such as vibration, as failure criteria," reports Roger Feist on the results of extensive investigations in the field. Achenbach was especially convinced by the Bachmann M1 system s robust mechanical design, its fan-free operation at ambient temperatures of up to 60 C and the exclusive use of semiconductor memories instead of (moving) magnetic data storage media. Proprietary solutions avoided Ultimately, manageability, that is, operability and serviceability, help determine the productivity and availability of a system. Here, too, Achenbach sets standards. Thanks to the open system structure of the M1, proprietary solutions in programming could be avoided and the automation technology implemented consistently on the basis of the internationally valid standard IEC "That s important, since over 90 percent of the systems are shipped abroad, mostly outside Europe," says Roger Feist and adds: "But thanks to the universal network capability of the M1, remote servicing, if needed, is possible from every location in the world, for example via the Internet with the corresponding backup procedures." Helping determine the evenness of the strip: Hundreds of individually controlled coolant nozzles. 37

38 WITH SAFE PRESSURE Integrated safety solution for dry presses 38

39 industry.application Products made of metal powders have now become indispensable in many industries and application areas. The mechanical presses from DORST Technologies are among the world s leading machines for dry pressing of metallic or ceramic powders. The company used the completely integrated safety solution of the Bachmann M1 automation system when developing a new servo-electric mechanical press. DORST Technologies is a medium-sized company with approximately 450 employees. Corporate headquarters and the company s technical center are located approximately 50 km south of Munich, Germany in Kochel am See. Here research is devoted to intelligent system solutions for machines and systems for the production of ceramic and powder metallurgical products; in this regard the preparation of raw materials and forming are among the company s areas of specialization. The knowledge associated with the individual process steps and the diverse influence variables involved in the production of several end products make DORST an internationally recognized expert in forming ceramic and metal powder. Maximum precision for automotive engineering Parts consisting of pressed metal powders play an ever greater role, particularly in automotive engineering: Today synchronous hubs for passenger car transmissions, timing belt pulleys, shock absorber parts, valve guides and much more are manufactured on dry press machines from DORST. Due to the extremely low level of residual moisture of the pressed raw material, the dry presses are particularly well suited for mass-production of dimensionally accurate parts. For manufacturing, the finest grades of granulates and powders are compacted in steel dies that are profiled appropriately for the part that will be produced. "When filling the die, even distribution of the material is extremely important", explains Herbert Gröbl, Director of Development Control Technology at DORST. Inhomogeneous density distributions could cause the parts to warp or even crack and thus negatively influence the load capacity and precision of the component", continues Herbert Gröbl. Consequently treatment of the basic raw material also plays an important role, since the parameters and characteristics not only need to be clearly defined but they must also be reproducible. 50 tons of pressing force, maximum safety The new EP50 servo-electric press from DORST offers a pressing force of 50 tons (500 kn) and works with up to 60 lift cycles a minute. This requires a high level of safety for operating personnel, which is ensured by the integrated safety solution from Bachmann. The press is completely enclosed in operation. Access is only possible through the lockable protective doors that can only be unlocked under defined conditions: "This means that the machine must The company located close to Munich (Germany) offers with its 450 employees intelligent system solutions for machines and systems for the production of ceramic and powder metallurgical products.» With the integrated safety solution from Bachmann we achieve a high level of machine availability. «Herbert Gröbl, Director of Development Control Technology at DORST Technologies 39

40 50 tons of pressure, up to 60 times a minute: With the DORST EP50 servo-electric press dimensionally precise, mass-produced articles are created. Dry presses In the dry pressing process a granulate is compacted by a top punch and a bottom punch in an extrusion die. The powder is dosed and supplied via a filling device. For the one-column presses only the top punch is moved, for the two-column presses both top punch as well as bottom punch are moved. The pressed article is lifted out of the die via an ejector and automatically removed by a gripper. be at a standstill and the axes must be in safe position", explains Herbert Gröbl. It is only possible to operate the press with the door open when tools are changed, and then operation is only possible at a safely reduced speed (Safe Limited Speed). If an emergency stop button is activated or if the voltage monitor trips all axes are brought to a standstill with maximum delay. Then a "Safe Torque Off" occurs, i.e. drive torque is switched off. "Safe Torque Off" is directly triggered in "Tool Change" mode. Easy integration is convincing The easy integration of the safety solution in the standard control system convinced DORST immediately, as the system is based on consistent hardware. All process variables can be accessed in a consistent level. "With communication via the Bachmann Standard Variable Interface (SVI) we achieve cost-saving potential", the Director of Development describes the advantages: diagnostic I/Os are no longer required, the hardware and wiring complexity is reduced, there are fewer error sources. "All this means lower costs and is an ideal prerequisite for faster amortization of the system" is how Herbert Gröbl describes an important customer benefit of the DORST press that is automated with the Bachmann M1. DORST also saves time and costs with the Bachmann solution when programming the system. "With the safety components integrated in the Bachmann Safety Developer in accordance with PLCopen we succeeded in quickly and easily implementing the safety application", continues Herbert Gröbl referring to his experiences in setting up the system. By using the function blocks (Safety Compounds) the firm succeeded with a clean, easy to understand structuring. "Of crucial importance for us in this regard was the fact that we can use these blocks in a project-overlapping manner and thus can quickly implement them in similar machines or systems," explains Herbert Gröbl. Easy remote maintenance of the safety solution DORST presses are installed in more than 70 countries around the world. Equally important for companies as well as customers is the possibility of maintaining the safety solution remotely, directly via the M1. The Solution- Center engineering tool offers the service technician extensive diagnostic possibilities and 40

41 industry.application thus permits simplified troubleshooting, cited the Director of Development as an important detail. Positioned as a trendsetter The names DORST and Bachmann stand for high quality, for innovation, technology leadership and strong customer orientation. The close collaboration of the two companies produced a trend-setting solution for safe automation. With the new generation of the servo-electric press DORST succeeds with a successful synthesis of engineering and technology know-how. In this regard automation with the Bachmann M1 system and its integrated safety solution promises even higher level of safety and system availability for the owner. Bachmann Safety Control The scalable solution The SLC284 safety controller has been developed in accordance with the latest research knowledge. All data processing is executed with two channels in a homogeneous, redundant structure with self-diagnostics: Two processors continuously execute all calculations in tandem and cyclically compare the results. Thanks to the integrated inputs and outputs of the SLC284, safety tasks can be directly implemented without the use of additional modules. With the safe digital input and output modules SDI208 and SDO204, the number of channels required for more extensive applica- tions are provided. Thus the Bachmann Safety System can be optimally config- ured for a wide variety of applications. All safety modules can be plugged into the M1 automation system at any point desired, in particular, they can also be plugged into substations. 41

42 SHOT FOR SHOT PERFECT Automation of die-casting machines Die-casting, an industrial casting process, is used for the mass production of structural parts made from metals such as aluminium, zinc or magnesium. For the past ten years Oskar Frech GmbH + Co. KG, based in the Swabian town of Schorndorf (Germany), has been using the Bachmann M1 system for the automation of its die-casting machines. 42

43 industry.application» We feel the very close partnerbased support of Bachmann. «Rainer Sautter, Head of Engineering Control Systems at Frech Oskar Frech GmbH + Co. KG was founded in 1949, and developed in the last six decades to the world's leading supplier of die-casting technologies. In 1959 the first hot chamber die-casting machine was launched on the market, a technology that is used today for the high volume production of housings for cell phones and notebooks. In 1967 Frech added cold chamber die-casting machines to its product range. The south German manufacturer constructs complete die-casting cells worldwide for the production of very small die-cast parts right through to motor blocks and chassis components for vehicles. The automation is critical The automation of a manufacturing process determines its competitiveness, as Rainer Sautter, head of open and closed-loop technology at Frech, explained. In die-casting the reliability and reproducibility of manufacturing processes are key priorities. This is why Frech has been using Bachmann's M1 controller as the basis of its DATADIALOG automation system for several years. It has now been over ten years since we decided to replace our own outdated system with an OEM solution, Rainer Sautter recounted the beginnings of the cooperation with Bachmann. After an extensive evaluation of a wide range of industrial controllers, the M1 system was chosen. Our casting cells have a highly modular design and comprise melting and metering technology, spraying equipment, heating and cooling devices, die-cast molds and removal devices, in addition to the actual machine, Rainer Sautter describes the general conditions of the automated systems. A suitable level of flexibility in the automation system and optimum adaptability to the individual requirements of the overall plant were therefore also important selection criteria. What is more: When it comes to a solution for a new requirement, we still feel today the very close partner-based support of Bachmann, Rainer Sautter adds. In 2007 Frech took over the die-casting business of Müller Weingarten AG. As a result Frech has become the only supplier worldwide that covers all technologies and closing forces. The machine controllers of the acquired series were later fitted with the DATADIALOG system in some applications. Fast cycle times Depending on the size of the machine, up to 1,000 shots per hour are possible. Shot per hour, as the specialist calls the high-pressure and high-speed die-cast pressing of the molten metal in the mold, is an expression of the productivity of a die-casting machine. Many parameters influence here the optimum casting result, which requires a high level of performance from the control system with the required short cycle times. For example, with every shot we measure the temperatures at various points in the process, the filling time of the mold, the press speed, absolute pressures and the pressure rise times, as well as monitoring and controlling the periphery and much more, Rainer Sautter lists the extensive range of closed-loop and open-loop control variables. The most powerful cold chamber die-casting machines have enormous dimensions: Weighing several hundred tons, they are heavy and Oskar Frech GmbH + Co. KG has around 700 employees at the Schorndorf plant and in 17 branches worldwide. 43

44 Die-casting In the die-casting process, molten metal such as zinc, magnesium or aluminium is pressed in a mold at high pressure and at very high speed. Specialists talk here of a shot. The divided mold is mounted on a moving platen and a fixed platen. Due to the high pressure, the locking forces required in the machine for the mold are enormous and for large parts amount to several thousand tons. On hot chamber die-casting machines, casting vessels and casting pistons are constantly in the molten metal. Alloys with a high melting point are cast in the cold chamber die-casting process in which the casting set is located outside of the molten metal. Die-cast parts have smooth surfaces and clean edges, with achievable tolerances of μm depending on the alloy used. Wall thicknesses of less than half a millimeter are possible depending on the material used. GDK cold chamber die-casting machine from Frech: Up to 5,000 tons (50,000 kn) closing force. (construction in the assembly plant prior to painting.) reach lengths of over 20 meters, with up to 5 meters in height. For these kinds of machines we rely on a distributed automation system, Sautter describes the topology of the control system. The remote units are networked via the optical FASTBUS with the central controller on which all the closed-loop control processes are implemented. Robustness required The robustness of the entire system structure is critical for our applications, Rainer Sautter states a further reason for selecting the Bachmann system. The ambient conditions present in a foundry plant are harsh. Heat, dust, vapors, vibrations with pressures of 200 MPa and more also place demanding requirements on the controller. The engineers at Frech therefore appreciate the stable mechanical design of the M1 system. According to Rainer Sautter, the specified operating temperature range up to +60 C provides them with the safety they need. Flexible operation also at distance The die-casting machine visualization provided by Frech on Bachmann terminals is one of the best HMI interfaces in the world, Rainer Sautter proudly states, This is due to its highly intuitive operation. The documentation of all die-casting parameters moreover allows the gap-free monitoring of the production and parts quality. This is critical for the process safety required by the user. Over 55 percent of Frech systems are exported. All of them can be accessed by the service department in Schorndorf via a remote connection, thus enabling the rapid diagnostics and maintenance of installed systems worldwide. As manufacturers, we consider our fast and reliable support of customers as an indispensable requirement for absolute excellence, as Rainer Sautter describes Frech's service philosophy. 44

46 WELDED RIMS IN RECORD TIME A steel rim in five steps The development of machines that produce complex formed metal components while at the same time maintaining maximum productivity and profitability was and is the declared goal of the company Fontijne Grotnes BV throughout its more than 100 year history. However, increasing demands placed on the load capacity of the produced parts in the automotive area especially call for ever-narrower manufacturing tolerances and reproducible high quality. The company is located in the Netherlands, in Vlaardingen near Rotterdam, and with its approximately 140 employees develops and produces amongst other things customer-specific machinery to produce steel wheel rims, and is one of the leading companies in Europe in this field. In order to meet these demands, the engineers at Fontijne Grotnes use comprehensive simulations to verify and optimize the production process long before their machines are constructed. Using "M-Target for Simulink " and the Bachmann M1 automation system in their newest generation of wheel rim welding machines, the development time was slashed and a performance unknown up to now was achieved. The range of the rim production machinery of Fontijne Grotnes goes from fully and partially-automated machines to produce very narrow rims for car spare wheels to rims of substantial size for lorries. With a production capacity of up to 1,000 rims per hour raw material cross sections from 350 mm 2 up to 3,000 mm 2 must be processed on the machine. In the first step of the production process, the steel raw material is uncoiled from the large coils it is delivered on and cut to size (cut-tolength line). The cylindrical hollow forms are shaped out of these pre-cut parts (preparation line). In the line that follows, the blanks are flared, profiled and expanded to the required circumference and brought into their final shape (profiling line). The final product i.e. the steel wheel rim is already recognisable. When assembling in the assembly line, the leak tightness of the rim is checked, the hole for the valve is punched and the mounting disc is fitted and MIG-welded. Finally the rims are stove-enamelled. Great expertise lies in the preparation of the blanks "We were driven by two important criteria during the new development of the rim welding machine," says Michel Leen, Manager Engineering at Fontijne Grotnes, explaining the considerations of the company. "We wanted to achieve a consistently high welding quality independent of the respective machine operator while maintaining the maximum output. Furthermore, the energy consumption was to be minimized during the welding process." Welding is also the heart of the whole steel rim production line. To this end, work was done on describing and quantifying those factors in 46

47 industry.application the welding process that determine the quality during a cooperative research project spanning several years with the Materials Innovation Institute (M2i) and the university in Delft (Netherlands). Based on comprehensive material analysis a thermo-mechanical-electrical models was developed that forms the basis for a completelely new welding strategy. The result is a very intelligent model that forms the basis for a completely new welding strategy. Roughly speaking, welding the blank is divided into two phases. Phase one comprises a temperature and pressure control: The rim blank that has already been bent into cylindrical form is introduced to the welding machine and heated under pressure and regulated electricity input. In the welding phase that follows the two ends of the cylinder form are pressed» Bachmann made an important contribution to this success. «together using position control, charged with a defined direct current and welded. This is also known as resistance butt welding, a form of resistance welding. "We have managed to markedly reduce the expansion of the weld seam and at the same time improve the quality using the new closed loop control," says Michel Leen and adds, "We have been able to cut the energy consumption during welding by about 20 per cent and noticeably reduce the number of rejects." Michel Leen, Manager Engineering, Fontijne Grotnes 1:1 implementation of the model thanks to M-Target for Simulink The actual welding process only takes a fraction more than a second. During this process a number of parameters must be recorded and 47

48 Machine using the optimized welding process immediately incorporated into the loop. "So we had to look for a control system that allowed extremely short cycle times," says Michel Leen and adds. "With the Bachmann M1 we found a system that easily delivers the required performance." Rapid porting to the real system "We had simulated the model in Simulink and successfully implemented it in the dspace laboratory system," says Michel Leen. "After that, we had planned 3-4 months for the porting of the Simulink model to IEC61131 for our previous industrial controlling system," said Mr. Leen explaining the original plan. "So you can imagine our surprise when the Bachmann engineers presented the transfer of our model onto the M1 within a matter of hours using M-Target for Simulink." However, this solution presented the specialists at Fontijne Grotnes with other advantages besides the huge gain of time. Thanks to the automatic porting, the model could be transferred to the control system without errors and without being simplified, and the respective simulation findings could always immediately be fed back into the system. Because the Simulink target is deeply embedded within the M1 software, the process could be directly monitored and optimized using Simulink during operations. The functionalities of cross communication that are part of the M-Target for Simulink solution made it possible to embed the Simulink solution seamlessly into the conventional automa- Detail of the production process of a steel rim: welding is the central process 48

"That way we were able to cut our time-to-market by at least six months," says Fontijne Grotnes Mr. Michel Leen, clearly more than satisfied with the Bachmann solution. Successful in operation Meanwhile, the new rim welding system is being tested by one of the leading manufacturers of car wheel rims in Europe. The new system makes the production result significantly more independent of the material used and also from the experience and sensitivity of the operator, who previously had to manually influence the welding process. Thus meaning that Fontijne Grotnes has succeeded in greatly reducing the number of rejects at an output of 1000 rims per hour. "With the new system we have impressively underscored our pioneering role in rim production machines in keeping with the highest automotive standards," says Michel Leen. "Bachmann made an important contribution to this success with the functionalities of automatic porting of the Simulink results to the control system and the performance of the M1 systems."» With M-Target for Simulink we saved more than half an employee year of development time. «Michel Leen, Manager Engineering, Fontijne Grotnes Welded cylindrical steel rim blank 49

50 M1 INCREASES FLEXIBILITY AND PROTECTS KNOW-HOW How the steel processing specialist uses controls 50

51 industry.application Schumag AG is a medium-sized machine-building company and manufacturers machines for drawing solid material as well as cold-drawn steel systems, loop and polishing machines and copper tube systems. The company also fulfills individual customer wishes regarding control technology. The following article shows how Schumag, with the help of Bachmann control technology, avoids constant reprogramming and simultaneously protects its know-how. Aachen lies in the northwest of the Eifel mountains. Schumag AG has its headquarters here. In the course of its 175-year history, the company has developed from a needle manufacturer to a company with special expertise in the treatment of solid materials and tubes. Besides machine and plant construction for the steel and nonferrous metals industry, Schumag produces precision parts to customer specifications (diesel injection systems, pumps, speedometer parts, etc.) and fabricates precision standard parts for stamping tools and mold-making. Schumag currently employs a total of 1,100 people and achieves annual sales between 100 and 130 million euros. Pulling, cutting, aligning, beveling, grinding and polishing are among the disciplines that Schumag performs during machine building and plant construction. All machines have modular design, that is, customers can individually configure their machines within certain parameters to suit their needs. The same holds for the control technology particularly with the many international customers. But that also has its problems. "Earlier, we developed and produced the hardware for our entire control technology ourselves, and if there was software, we wrote it ourselves," explains Hubert Stiel, software developer at Schumag AG. "Since we don t need large numbers we normally sell only one controller per machine» The performance of Bachmann was impressive. «that no longer paid off." And so we decided to find a system in which the hardware is maintained by the supplier, but the machine-specific functions could remain in our own hand. After a long search, we came across the Bachmann company: The M1 control platform from Bachmann electronic suited us exactly: from the hardware concept, software, and also the service," says Johannes Warns, E-Design department head at Schumag. The first project was creation of a flying saw. The first machine with Bachmann controller was placed in operation in 2002 by a customer in Nuremberg. "Since then, we ve shipped around 100 flying saws and cutters. The feed speed ranges from 80 to 150 m/min. There are also special applications: they re no longer flying saws but rotating shears with two crank arms. They meanwhile achieve speeds of up to 300 m per minute with cutting-length tolerances of ±2 mm," Johannes Warns explains. Hubert Stiel, software development at Schumag AG Advantages of the Bachmann M1 The Bachmann M1 controller is based on Intel processors which, due to their power efficiency, are particularly suited for use in the fan-free industrial arena at up to 60 C. Schumag sees the advantage of the Bachmann M1 controller also in the hardware s universality: "We can use the M1 for various functions and adapt the Schumag AG is a medium-sized machine building company and manufacturers machines for drawing solid material as well as cold-drawn steel systems, loop and polishing machines and copper tube systems. 51

52 software very flexibly," says Hubert Stiel, software developer at Schumag AG. The second step after the saw applications and the flying shears was then a spiral winder, more or less a waste product of the flying saw. "In addition, there is a so-called sort controller, whose purpose is to assign errors detected in the production process to the rejected cut rods at the end of the machine and sorted accordingly into good and bad sides," says Stiel, explaining the machine components. From the module controller to the core machine Schumag has developed a so-called peeling machine with the Bachmann M1. This is much more complex than the earlier applications. The M1 is used here for the core machine. For peripheral functions, Schumag relies on various controllers, also from other manufacturers. "After all, over half of the machines are exported outside Europe," Warns explains. A further advantage at Bachmann is that the core know-how can be delivered as a black box for installers, software developer Stiel adds. There are defined interfaces for peripheral control. That is, the actual initial start up does not run in the software. Errors that arise during start-up must be searched for outside the core founctions. "That shortens the start-up time for us, since we can fall back on building blocks about which we can say exactly that they work without error. The installers cannot look into the source code. And so we don t run the danger that each machine gets a new software version." And Warns adds: "We strongly limited the degrees of freedom of the installers and so were able to reduce start-up times considerably." Simple programming Stiel is also visibly convinced about the performance itself: He prefers to program in structured text. On the question of whether programming in C was a possibility for him, he referred to the available performance: Programming in C has not been necessary. The performance is completely sufficient. "We are currently not programming optimally in terms of time. We can program it down nicely. Then it's very fast. You don't have to fall back on optimised programming procedures. It's a very elegant tool", he enthuses. High performance With a fully built-up peeling machine, while there are only around 40 digital inputs and 30 digital outputs to supply, there are between 6 and 10 adjusting axes that are also positioncontrolled. Stiel divides the jobs into various tasks: The tasks that make the adjustments are not very time-critical and are accordingly placed on a long task cycle. The critical axis regulations, in contrast, are placed on a short task. "That is the advantage of the Bachmann controller: You can break up the job the way you need to, and then it runs that way and is also controllable. Things are different with a classical PLC; there it really depends on the conditions, how long the cycle time is," says the E-Design department head, Johannes Warns. And he adds: "Fortunately, we don t have that» The M1 controller platform from Bachmann electronic suited us exactly: from the hardware concept, the software and the service.«johannes Warns, E-Design department head at Schumag AG 52

53 industry.application with Bachmann. The cycle times are constant, which is very important, particularly for position control. The determinism on the system is always clearly maintained for every task. That is a very important aspect." Preventive maintenance One point that is becoming more and more important for the customers is preventive maintenance. For the Schumag peeling machine, this means preventive maintenance on the bearings. If changes are identified here, a planned machine maintenance interval can be used to check the bearings. But such functions could be used well for changes in the peeling process, that is, knife wear. "The peeling knives that peel away the material have a certain service life. For over 80 % of this service lif, the knives are stable. Only at the end do they change," Johannes Warns explains. If the quality that the knives still have could be reliably detected, the knives could be changed before the first bad rod comes out of the machine. And the cost of the peel product is very significant. "Throwing away a rod can cost a few hundred euros, depending on the material it s made of," Warns explains. "That goes up to titanium peeling, where even the shavings are collected." On the other hand: Every half hour longer that the knives can be used saves money. Communication leaves nothing to be desired Also regarding communication ability, the Bachmann controller leaves nothing to be desired: For pure data communication, Schumag uses PROFIBUS. The few time-critical signals are recorded directly over IOs. The heart of the Schumag PM peeling machine: the feed unit. The material is fed and also cut, if desired, at up to 60 m/min. 53

55 industry.application A PRECISE LOOK Software oscilloscope shows its strengths The Swiss company soplar sa based in Altstätten, Switzerland has for more than 30 years concentrated on the development, manufacture and maintenance of extrusion blow molding machines and tools, as well as stretch-blow molding machines. Renowned manufacturers of foodstuffs, cosmetics, household and laundry care products, as well as oils and lubricants, rely on their systems. Behind the continuous victory procession of plastic bottles lies soplar's recipe for success, consisting of innovations, customized engineering, high quality plant components and consistent customer care. More than 1,000 machines in 35 countries are testament to the creative and efficient team at soplar. From Altstaetten in Switzerland the company supplies its systems to all corners of the globe and with its subsidiary soplar (India) Pvt. Ltd., has direct presence in the prospering Asian market. This specialist in extrusion blow molding and stretch blow molding machines relies on Bachmann's M1 automation system throughout on all its machinery. The Scope 3.0 software oscilloscope is also tried and tested daily. A tool for data logging and analysis are indispensable, particularly with the development of new machines and plants. Bachmann s Scope product series has been used at soplar sa for a long time. These products are thus in use everywhere in the company by the developers and mechanics, as well as by the process and service technicians. High speed troubleshooting We primarily monitor path generators during the development phase, and any timing problems occurring in positioning tasks are examined, Stefan Spiegel, working in the Control Engineering department at soplar sa, describes one of the main applications of Scope. A number of process variables are recorded in a 2 millisecond cycle here. A task that does not present any problem for the highly capable M1 controller with the Scope software module. With a few clicks of the mouse in the analysis tool, the data can then be presented in a graph for further processing. The differentiation of curves with equally spaced X data is often used by us in order to immediately highlight any errors in path movements and positions, Stefan Spiegel continues. The display makes the difference The powerful recording module produces an extensive data set in no time. However, this data only becomes useful if the right analysis tool is available as well. That is why at soplar we appreciate the functions of Scope 3.0: soplar sa was founded in 1978 and is one of the leading manufacturers of extrusion blow molding and stretch-blow molding machines. The company is based in Altstätten, Switzerland, and has 180 employees worldwide. 55

56 Rapid troubleshooting: Scope 3.0 provides valuable services during the development and commissioning of machines and plants. The data is often not displayed over time at all, but in relation to another data sequence, the so-called X/Y chart display, Stefan Spiegel explains and adds: This allows us for example to visualize and examine the collision space of two axes simply a task that could not be completed so easily without this kind of tool. Ideal also for productive operation However, the data recorder is not just suitable as a tool in development and commissioning. It has a large number of applications in production. Service technicians are often deployed on site if problems occur on a machine. They then have to wait until the fault occurs again and can be reproduced, Stefan Spiegel describes a typical scenario and adds: Only in this way can the fault also be rectified quickly and reliably. The new Scope 3.0 makes this waiting unnecessary since» Bachmann has once more demonstrated its leading position with Scope 3.0. «the data recorder is supplied with the machine. Appropriate start trigger configurations make it permanently ready to record so that a fault can be logged already the first time it occurs. Several of these recording configurations can be stored in order to cover all relevant faults. Easy collaboration It is often necessary to involve several experts in the troubleshooting process or in finding a solution. It is tremendously important here to be able to exchange the data between each other simply and to also display it in exactly the same way, Stefan Spiegel explains. Stefan Spiegel, Control Engineering at soplar Only in this way can trouble-free collaboration and the correct interpretation of an instruction given over the phone be ensured. With Scope 3.0 these kinds of tasks are easy: Only one file is used for each recording, both on the M1 controller and on the PC. A local technician can open a file, select the relevant data and posi- 56

57 industry.application Very satisfied: The team at soplar sa has been using the Scope products from Bachmann for a long time. tion the appropriate measuring cursors. If he then sends this file to someone, the recipient will see exactly the same display, since everything is displayed exactly as it was saved, right through to the zoom level. Performance with tradition We have been working with the software oscilloscopes of Bachmann for a long time and appreciate them very much, Stefan Spiegel sums up and states: Bachmann has once more demonstrated its leading position with Scope 3.0 and has once again simply done something very good! High precision: The time relationships of various process variables are analyzed and the exact values can be read out with the measuring cursor. 57

58 THE TWO BISHOPS Why it helps to stay human in technology We at Bachmann would never force people to follow convention but give them the space they need to develop their own abilities. This allows the unfolding of new and unconventional solutions during a chess break as much as during an impromptu meeting. We don't work next to each other but with each other. This provides the basis of trust that also connects our customers. One strategy tip from chess says: Keep the space open for your two bishops to effectively use their enormous scope. This is what we want to live. Together with you. Every day. 58
