7 1 Task 1 Task Introduction In the future, energy management will become increasingly important. Cutting costs by saving energy in production is an approach that has already been used for some time. Recently, the focus has also shifted to shorter non-production times from short breaks to idle shifts. Would it not be possible to set smaller, currently not required plant sections into energy saving mode while the rest of the plant continues with the production? All this could significantly improve the energy balance of a production unit. The decision to use PROFINET provides the conditions for new and future-oriented energy management. Future-oriented energy management means: units are no longer switched off using the conventional mains switch method but on a fine-grained basis via the network! The general supply system of the components remains activated and the components initiated by a command enter a defined energy-saving mode. PROFIenergy is a profile defined by the PROFINET user organization. It provides the prerequisites for a vendor-independent system that can be generally used to switch off individual loads or entire production units flexibly, on short notice and intelligently. SIEMENS supports PROFIenergy /3/ with implementations in the SIMATIC automation system. The numerous innovations of the new SIMATIC ET 200SP include the possibility for a coordinated and central switch-off of the I/O modules independently and individually via PROFIenergy during pauses. 1.0, Entry ID:

8 1 Task Overview of the automation task The figure below provides an overview of the automation task. Figure 1-1 Feed Processing Discharge This application describes the switch-off of automation components using an example from production - here a production line with robots. This plant consists of one feeding and one discharging conveyor belt and a processing unit. The conveyors are connected at a ET 200SP. For reasons of clarification the processing unit is a black box that is switched on/off via an own ET 200SP. In terms of energy saving the PROFIenergy does not focus on the drive motors since these are switched off in case of a production stop. It rather concentrates on the numerous sensors and further electronic components. Description of the automation task During a pause the components of the automation component shall be switched off. The spontaneous or regularly planned break can be initiated by the user via the controller. After the production has stopped parts of the distributed periphery are switched off via applicable PROFIenergy commands. Before the production is started again the necessary automation components are switched on again. The following application description shows step by step how such an application can be realized using the SIMATIC S7 ET 200SP with integrated PROFIenergy functionality , Entry ID:

9 1 Task Scenarios This application example presents the following switch-on and switch-off scenarios. Table 1-1 Requirement Switching off several components of the plant Selective switch-off Selective switch-on Switching on several components of the plant Explanation If no staggered switch-off is required; which means that plant parts are switched off at once Switch off individual components of the plant Coordinated shut-down, i.e. necessary because of the technological process Switch on individual components of the plant. Staggered switch-on Components of the plant that are not subject to a special switch-on sequence. 1.0, Entry ID:

10 2 Solution 2.1 Overview of the general solution 2 Solution 2.1 Overview of the general solution Schematic layout For this application, the PROFIenergy with Comfort Panel application was supplemented by two ET 200SP. The following figure gives a schematic overview of the most important components of the solution: Figure 2-1 PS CPU Comfort Panel Field-PG PROFINET ET 200SP ET 200SP Discharge Feed Processing Structure The plant described above is based on a distributed structure. Via two ET 200SP with several I/O groups each, the CPU controls the plant. The respective I/O modules have to supply the sensors and actuators with voltage to achieve appropriate energy savings. The energy is saved by switching off the encoder supply of the modules. A direct supply of the sensors and actuators via a 24V bus would prevent a selective switch-off, hence the saving of energy. Input / visualization via Comfort Panel (HMI) is offered as an option. The same input fields and information are available in a watch table in STEP 7. The panel itself can also be simulated on the PG via the WinCC V11 Runtime , Entry ID:

11 Advantages of ET 200SP 2 Solution 2.1 Overview of the general solution The distributed I/O system is easy to operate and provides maximum efficiency in the switching cabinet due to its compact design. SIMATIC ET 200SP communicates via PROFINET. Its high speed and data rate yield a clearly stronger performance than previous systems. Topics not covered by this application This application does not contain a description of how to switch off a plant. This is already implemented into existing plants and differs too much from plant to plant. The following sections explain the basic functionality of the PROFIenergy profile and the FB PE_START_END function block (FB815). Our other PROFIenergy applications describe further PROFIenergy blocks and commands. There is no functional difference between the applications for STEP 7 V11 and STEP 7 V5.5. You can use the documents simultaneously for your information. Assumed knowledge Basic knowledge of automation engineering, SIMATIC, PROFINET and configuring with STEP 7 V11 and WinCC V11 (TIA Portal) is necessary. 1.0, Entry ID:

15 3 Basics 3 Basics 3.1 PROFIenergy profile This chapter explains the functions of PROFIenergy, especially the relation between the functional modules and the hardware. 3.1 PROFIenergy profile The PROFIenergy profile presents methods and techniques for implementing energy-saving functions into PROFINET IO devices. And not only manufacturerindependent into simple I/O devices but also into intelligent and complex devices. PROFIenergy consists of a group of methods that apart from parameterization and the actual start and stop commands are also used for recording the energy consumption. PROFIenergy is based on existing PROFINET mechanisms changes are not necessary. This enables PROFINET users to integrate PROFIenergy into existing plants, without having to make fundamental changes to the plant. PROFIenergy controller: A PLC, here the SIMATIC S7 CPU 317-2PN/DP. The user decides whether PROFIenergy management is integrated into an existing controller or left to an additional controller. PROFIenergy device: A PROFINET IO device with integrated PROFIenergy functionality. In this case, a SIMATIC S7 ET 200SP. The interface module of the ET 200SP provides the access point for the PROFIenergy control data records. The I/O modules do not have a separate PROFIenergy accesspoint. PROFIenergy always provides several energy-saving states of the PROFIenergy devices. In the application presented here, the following state is realized: OFF ( PAUSE ) and ON ( Ready ). Full PROFINET communication capability is provided in the OFF state. 1.0, Entry ID:

FC PE_ET200SP_1 (2) (FC10 and FC11): Combines the functions for the respective ET 200SP. Digital output module SFB WRREC: Sends the settings concerning the switching behavior of the I/O modules to the addressed ET 200SP. This block is not part of the PROFIenergy profile but supplements the SIMATIC-specific functions. FB PE_Start_End (FB815): Starts and stops the pause on the selected PROFIenergy devices and at the same time communicates the desired pause time. Program overview In this application, we show you the usage of the FB PE_START_END (FB815) and SFB WRREC blocks. Information on using the further PROFIenergy blocks is available in our other PROFIenergy applications in the Industry Online Support /2/. 1.0, Entry ID:

18 4 Functional Mechanisms of the Application 4.2 WRREC Write Data Record functionality 4.2 WRREC Write Data Record functionality This block is available in the TIA Portal V11 SP2 at Extended Instructions in the Distributed I/O folder. With this instruction you transfer a RECORD parameter data record to the IM156-6 PN interface module of the ET 200SP. With this data record, the switching behavior of the individual I/O modules during a PROFIenergy pause is defined. In this chapter, the structure of the RECORD parameter data record, which you require for PROFIenergy, is explained. The call parameters of the WRREC instruction, its behavior, and its STATUS messages are available in the Online Help of the TIA Portal. Configuration The IM of the ET 200SP is configured with the user program via the parameter data record (Version2), Index 3. The interface module distributes the PROFIenergy parameter to the I/O modules. The configuration of a further pause behavior is possible immediately after the start of the previous "Pause". Taking on the desired state for the subsequent pause is activated with a renewed "Start_Pause" command. The configuration can be written any numbers of time. The interface module checks the distribution of the parameters to the I/O modules and returns the result via the return value of the write job. For a negative return value, there are one or several I/O modules which have not accepted the parameter data record. In this case, for a coming "Start_Pause" command, the I/O modules behave according to their last PROFIenergy parameterization. For a positive return value, "Start_Pause" and "End_Pause" commands can be executed correctly. In the case of a failure of I/O module or station, the parameterization must be repeated via the parameter data record. The ET 200SP supports the settings of the "Pause" behavior. If a different behavior is required in a further "Pause", you need to reparameterize. The reaction (switch-off) of the I/O modules on PROFIenergy is related to the slot, i.e. all channels of the slot behave accordingly , Entry ID:

19 4 Functional Mechanisms of the Application 4.2 WRREC Write Data Record functionality Parameter data record In the parameter data record for PROFIenergy you define, which I/O modules (slots) are controlled via the PROFIenergy commands.

Error messages The feedback data record returns you the following error messages on demand: Table 4-2 Error code Meaning Remedy 80B1 H Impermissible length Check the length of the data record 80E0 H Error in the header information Check the header information 80E1 H Parameter error: At least one module does not support PROFIenergy One parameter value was wrongly coded Check the content of the data record and remove the configuration error before starting "Pause". Unrepaired configuration errors may lead to wrong switch-off behavior of the I/O modules. 1.0, Entry ID:

Switching off the encoder supply also causes the switch-off of the channel LEDs if no external encoder supply has been connected. Behavior when detecting errors Terminating a "Pause" The "missing supply voltage L+" error is independent of taking on the pause state and is reported during "Pause". All channels located on "PE_MODE_PROCEED" in pause mode report their error state as in production mode. For all channels which go to another pause mode, the following conditions apply: Switching off the encoder supply when entering the "Pause" does not prompt the "open circuit" and "short circuit" messages. During the "Pause", an error detection of "open circuit" and "short circuit" is not possible: For errors already pending prior to "Pause", the message remains. Coming and going errors are reported after the "Pause" has been terminated. The Pause is terminated in the following cases: "missing supply voltage L+" error occurred reparameterizing the I/O module with DS128.

27 4 Functional Mechanisms of the Application 4.4 FB PE_START_END (FB815) functionality 4.4 FB PE_START_END (FB815) functionality FB PE_START_END (FB815) is used to start and stop the pause for the specified PROFINET IO device, here ET 200SP. The PAUSE_TIME parameter provides the planned pause time for checking. The following applies: PAUSE_TIME >= PM-E_Pause_Min The minimum pause time PM-E_Pause_Min in which the PROFIenergy component still participates is stored in a parameter set of the module firmware. The purpose of this minimum pause time is to ensure that the module can be switched OFF and back ON within the pause time. For an ET 200SP, this time is 10 seconds. This means that the ET 200SP participates in pauses which last at least 10 seconds. After the pause time has elapsed, the module is not switched back on automatically and remains in the OFF state until the END command. This prevents the module from being switched back on in an uncoordinated manner, which may eventually result in unwanted load peaks. 1.0, Entry ID:

39 8 Operation of the Application 8.1 Overview There are 3 options to operate the plant: HMI panel HMI Runtime (equivalent to the panel) Watch table in STEP 7 (TIA Portal) 8 Operation of the Application 8.1 Overview There are no functional differences; exclusively the way how control bits are set differs. In a real application, a time- or event-controlled program would set the respective control bits. Please remember: If we talk in the following about switching off the PROFIenergy-module or about the "Discharging" etc. this does not mean the drives of the plant, but via the DI/DO, the sensors and actuators, so actually the limit switches, monitors for beltmisalignment and secondary drives in neutral. As mentioned already the very functions (belt drive) have to be switched off regularly before. 1.0, Entry ID:
