5 Application Description Automation Problem Application Description Content This application example will show you the basic requirements for cyclic data exchange using PROFIBUS between a Rockwell CompactLogix and Siemens ET200S I/O. Using the Hilscher PROFIBUS Module provides all of the integration opportunities between Rockwell and Siemens that PROFIBUS affords. 1 Automation Problem 1.1 Overview Introduction In production plants around the world, it is common for customers to have automation equipment from more than one supplier. There is also a need for this equipment to communicate, and at times to integrate components from different vendors into a single control system. In this application example, the Siemens ET200S I/O will be integrated with a Rockwell (Allen Bradley) CompactLogix Controller using PROFIBUS. Overview of the automation problem The figure below provides an overview of the desired configuration.

6 Application Description Automation Solution Requirements The integration solution must provide diagnostics and cyclic data transfer between the ET200S I/O and the Rockwell CompactLogix Controller. 2 Automation Solution 2.1 Overview of the overall solution Configuration Architecture PROFIBUS communications for the Rockwell CompactLogix Controller is achieved using a Hilscher GmbH PROFIBUS-DP Master module. This application example provides details on installing the Hilscher PROFIBUS-DP Master module into the CompactLogix controller and the details for configuring it to communicate with the ET200S I/O. Diagnostic features are also identified. Schematic layout The following figure schematically shows the major components required for the integration.

The configuration Version V1.0 Issue 2008/02/29 6/36

7 Application Description Automation Solution software will communicate with the CompactLogix Controller using the DF1 communications protocol through a serial port in the engineering workstation. The Rockwell communications software package RSLinx will be used to provide the DF1 protocol. The Hilscher System Configurator software, SYCON.net, also runs on the engineering workstation. It also communicates directly to the Hilscher PROFIBUS- DP Master module via a serial port. 2.2 Configuration Activities The following activities must occur in order to establish the PROFIBUS communications: The ControlLogix Controller hardware must be assembled correctly with the Hilscher PROFIBUS module. The ET200S hardware must be assembled. The ET200S GSD files must be added to the SYCON.net device catalog. The PROFIBUS network must be configured and downloaded to the Hilscher PROFIBUS module. Communications must be established between the engineering workstation and the CompactLogix controller using Rockwell RSLinx communications software. A new project must be created for the CompactLogix controller using the Rockwell RSLogix engineering software. Testing must be performed to verify that input points can be read and output points can be written. All this steps are shown in Details in chapter Configuration and Operation of the system. Advantages of this solution This solution provides existing Rockwell customers with the opportunity to use Siemens ET200S I/O. Version V1.0 Issue 2008/02/29 7/36

In order to configure and program the CompactLogix Controller, RSLinx must be configured. In the example application, communications between the engineering workstation and the controller is RSLinx running the DF1 protocol via the serial port of the computer. RSLinx runs as a service on the computer, so it is active once the computer starts up. The RSLinx Icon is located in the lower right area of the taskbar.

Once the Who Active window appears, the active path will animate by blinking the small icons to the left of an active path. Select the path. Once the path is highlighted, select the Set Project Path button. When the path is set, select the Download button. 3. Version V1.0 Issue 2008/02/29 28/36

29 4. Once the download completes, put the CompactLogix Controller into Run Mode. Select the Yes button to put the Controller in Run Mode. Note that the keyswitch should be in the remote (REM) position. Version V1.0 Issue 2008/02/29 29/36

30 4.8 Testing the ET200S Input/Output Modules Introduction NOTE The Hilscher PROFIBUS Master Module will begin communications with the ET200S DP Slave when the CompactLogix goes into Run Mode. No logic needs to be written for cyclic data exchange. The cyclic data from DP slaves are put into the PROFIBUS Master Module input and output area of the CPU. Refer to the Hilscher documentation for a complete explanation of the input and output areas (section 5). Input Module The first 88 bytes of the input area are reserved for diagnostic information. The actual data begins at byte 89. Table To view the data select Controller Tags of the RSLogix5000 project. Double click the Controller Tags item. 2. Version V1.0 Issue 2008/02/29 30/36

31 3. Expand the Local:3:I:Data tags (input tags for the module in slot 3) to word 44. Note that the value is zero Provide 24V to the first input channel of the ET200S input module. Note that the value changes to a one indicating that the data exchange is working correctly. 6. Version V1.0 Issue 2008/02/29 31/36

32 Output Module Table 4-9 Like the input area, the Hilscher PROFIBUS Master module has a reserved area at the beginning of the output area. Sixteen (16) bytes are reserved for output commands. This means output data to DP slaves begins at byte Expand the Local:3:O:Data tags to word 8. Write the value to a one and verify the first channel of the ET200S output card is on. 2. Version V1.0 Issue 2008/02/29 32/36

33 4.9 Diagnostic Information Introduction Table 4-10 The Hilscher PROFIBUS Master Module provides a wealth of diagnostic information. As mentioned earlier, the first 88 bytes of the input tag area of the module are reserved for diagnostic information. As an example, bytes (words 20-27) of the input tags has a bit for each DP slave to indicate that it is exchanging data with the DP Master. The bit is logical one (1) if data exchange is occurring and a logical zero (0) if the is no data exchange. 1. Expand the Local:3:I:Data tags to word 20. Note that the bit for DP slave 3 is a one indicating that data is being exchanged Remove the PROFIBUS cable from the ET200S interface module. 4. Note that the value goes to a zero indicating that the data exchange has stopped. Version V1.0 Issue 2008/02/29 33/36

34 5. Reconnect the cable and verify the bit goes to a logical one (1) again. NOTE The module also provides the ability to read status information directly from the DP slaves. Refer to the Hilscher documentation for more information. Additional Diagnostics In addition to the diagnostics that the 1769-DPM module provides to the Controller, the SYCON.net configuration tool also provides online diagnostics. In the video clip attachment SYCON Diagnostics you see a demonstration. Version V1.0 Issue 2008/02/29 34/36
