The central control unit is a SIMATIC S7-300 station with a CPU PN/DP. As PROFINET devices an ET 200S with IM PN and an IE/PB Link PN IO are connected via Ethernet. Since the IE/PB Link is used as a gateway between PROFINET IO and PROFIBUS, PROFIBUS modules can also be connected via this module. In this document the module is an ET 200S COMPACT. A PG/PC with Ethernet interface is used as configuration and programming device. Note The integration of a 2-port switch into the ET 200S enables a line topology of the cabling without further external switches. Version 1.0 Edition 05/15/06 6/37

9 Principles of Operation Valuable Information on PROFINET Principles of Operation Content The following chapter provides you with basic background information on PROFINET. 2 Valuable Information on PROFINET 2.1 General overview As the field bus PROFIBUS, the PROFINET technology is standardized and developed by the PROFIBUS user organization. PROFINET differentiates between two applications: PROFINET CBA (Component Based Automation) this version which was developed first defines the cross-vendor communication of intelligent automation components and plant parts at the control level. Using the SIMATIC imap interconnection editor, the communication between controllers is configured instead of programmed. PROFINET IO defines the connection of distributed field devices to central controllers via Ethernet and die cyclic transmission of I/O data. One of the main challenges for the development of PROFINET was to use Ethernet and other proven IT technologies in all fields of automation. Since its introduction, the PROFINET standard has managed to advance to the field bus level based on Ethernet, also enabling the transparent integration of existing field bus systems e.g. PROFIBUS. The essential advantages include: Achievement of an integrated communication and reduction of the interfaces Simplification of the engineering Simplification of the diagnostics Use of the existing know-how and protection of the investments already made IT world and automation world grow closer together. Version 1.0 Edition 05/15/06 9/37

10 Principles of Operation Valuable Information on PROFINET 2.2 PROFINET real-time communication As shown in the figure below, the Ethernet-based communication is scalable and provides three performance classes with different response times: TCP/IP (100ms): For open TCP communication (e.g. for the transmission of non-time-critical data: Parameterization, diagnostics) RT (10ms): Real-time communication for time-critical data (e.g. in factory automation: Cyclic data, event-controlled messages, alarms) IRT (1ms): Isochronous real-time for sophisticated applications (e.g. in motion control) Figure Functional model The PROFINET IO functional model resembles the model of PROFIBUS DP, but the master-slave procedure was converted into a providerconsumer model since all nodes have equal rights when using Ethernet. The devices of PROFINET IO are referred to as IO controller and IO device or IO supervisor. Version 1.0 Edition 05/15/06 10/37

11 Principles of Operation Valuable Information on PROFINET Table 2-1 Device type IO controller IO device IO supervisor Description Master for the input/output data of the field devices. Represents the communications interface of a controller. Corresponds to DP Master Class 1 Distributed field device Designation for an engineering and diagnostic station. Corresponds to DP Master Class 2 Figure 2-2 Configuration I/O data Interrupts PLC IO controller PG/PC IO supervisor Field device IO device Parameterization Status Diagnostics Existing field bus systems can be easily integrated into PROFINET. This is realized using a proxy; this proxy is either integrated into a PROFINET device or it is an autonomous device (e.g. SIMATIC NET IE PB Link PN IO). 2.4 Configuration Analogous to PROFIBUS DP, a plant engineering requires the devicespecific system data (GSD-XML files) of the used field devices. They are imported to the configuration tool (e.g. STEP7), which, based on the network data, establishes an address list for the IO controller. The planner assigns a unique logical name to each field device. The actual name assignment in the device is performed by the DCP (Discovery and Control Protocol) integrated in each IO device. To ensure that each device is detected as node on the Ethernet, an IP address has to assigned to each device. The IP addresses are generated by the configuration tool and loaded to the IO controller as the configuration. During the system startup, the controller assigns these configured IP addresses to the configured field devices. See the schematic representation below. Version 1.0 Edition 05/15/06 11/37

12 Principles of Operation Valuable Information on PROFINET Figure Diagnostics PROFINET offers a powerful diagnostic concept which comprises each device configured in PROFINET, also network components which are PROFINET devices (e.g. SCALANCE X208). This device diagnostics is divided into three stages: Error on the device: Failure of a station Error on the slot: Defect of an individual module Channel error: E.g. wire break If an error occurs, the corresponding IO device generates a diagnostic interrupt which is reported to the controller. The user is responsible for its evaluation. In addition, this diagnostic information can be read and evaluated directly from a connected IO supervisor. Version 1.0 Edition 05/15/06 12/37

Overview This chapter uses the simulation of the failures of a module and an assembly to show the diagnostic capabilities within the S7 project. STEP 7 tools are used exclusively. Note For the diagnostics of the individual modules via the LED displays, please use the corresponding operating instructions of the device. The system description has to be observed for the diagnostics via the user program. 5.1 Activating diagnostic function in STEP 7 Basis Table 5-1 No. Instruction Screen shot 1. Open HW Config and select the online view of the configuration via Station > Open ONLINE 2. This overview diagnostics shows all parameterized stations.

33 Diagnostics with STEP7 Basis 5.2 Diagnostics of a module failure Table 5-2 No. Instruction Screen shot 1. The first fault scenario is to provoke a failure of the I/O module. Unplug an I/O module, e.g. the second 2 DI module, from the IM PN. Press the F5 key to update the display. This display appears in the overview. 2. Double-clicking Device starts the detailed diagnostics of the device. It is indicated that an error has occurred, the exact information on the error is provided in IO Device Diagnostics. 3. After selecting IO Device Diagnostics, the error message can be read in plain text in Standard Diagnostics in the middle of the window. Here the failure or the unplugging of the module in slot 3 was diagnosed. As soon as you reinsert the module, the error message disappears after the update. Version 1.0 Edition 05/15/06 33/37

34 Diagnostics with STEP7 Basis 5.3 Diagnostics of an open circuit Note The fault mask of the SCALANCE can, according to manual /1/, be configured via the pushbutton on the front of the SCLANCE or the web interface. Short instructions for configuring the fault mask The fastest way to define the fault mask is to use the Set pushbutton on the SCALANCE X208. The following steps have to be performed: Press the pushbutton on the front, on the right below the RJ45 ports. After pressing the pushbutton for approximately 3 seconds, the currently valid fault mask is displayed. The monitored ports flash at 5 Hz. After the 3 seconds the new fault mask is displayed. The flashing frequency reduces to 2.5 Hz. After another 3 seconds the new fault mask is applied and saved. The monitored ports are now indicated by permanently lit LEDs until the pushbutton is released. The configuration is now completed. Version 1.0 Edition 05/15/06 34/37

35 Diagnostics with STEP7 Basis Table 5-3 No. Instruction Screen shot 1.
