1、QUESTION:How can I configure a CPU 215-2DP as DP slave? ANSWER:This entry describes how to configure a CPU 215-2DP as slave on a CPU 315-2DP as master. STEP 7 V5.x and Micro/WIN 32 V3.x are used for the configuration. Configuring in STEP 7 V5 1. Create a new project. 2. Add an S7-300 station to the

2、project. 3. Open the hardware editor. 4. Add the power supply and the CPU 315-2DP. For test purposes, under Properties for the CPU configure the Marker Byte 1 as clock marker. 5. Attach the CPU 215-2DP to the DP segment. The CPU215-2DP is located in the hardware catalog underPROFIBUS DP DP VO SLAVES

3、IMATIC S7-200 CPU 215-2DP 6. You must add an input/output module to the CPU 215-2DP. In this example a 2 bytes out / 2 bytes in module is used. The module is located in the hardware catalog under.S7-200 CPU 215-2DP.Mark the CPU 215-2DP. Drag-and-drop the module to the open table. 7. Create the addre

4、sses for the input and output areas of the slave. 8. Double-click the module and enter the start addresses in the dialog that opens. 9. Enter the memory area in which the CPU 215-2DP is to store the inputs and outputs. 10. Double-click the CPU 215-2DP. The Properties - DP slave opens. 11. In the Par

5、ameter Assignment tab you specify the offset in the V memory of the CPU 215-2DP an. In the example the offset is 5000. This means that the DP inputs are in VB5000 or VB5001 and the DP outputs in VB5002 or VB5003. 12. Set the bus parameters. In the General tab click the PROFIBUS button. In the dialog

6、 that opens go to the Network Settings tab.Note:In STEP 7 - Micro / WIN you can only set the transfer rates to a value of 19.2 Kbaud. But the bus system can and must be much higher (up to 12 Mbaud). The CPU then sets itself automatically to this baud rate. This happens regardless of what has been se

7、t in STEP 7 - Micro / WIN. 13. Set 19.2 kbaud as transmission rate. 14. Save the hardware configuration. 15. For the test, the clock marker is to be transferred into the output byte 0. This happens, for example, in the OB1 with the following commandsL MB 1T AB 0 16. Load the configuration into the C

8、PU 315-2DP Parameterizing the CPU 215-2DP in Micro/WIN 32 1. Open Micro/WIN 32 and create a new project. Check whether the connection to the CPU 215-2DP is available. 2. If necessary, adapt the CPU type to the hardware you have. 3. Double-click the system block. Assign the parameters for Interface 1

9、 for the PROFIBUS communication. Important: The settings for the interface must match the PROFIBUS settings in STEP 7:PROFIBUS Address 4, Highest Address 126, Baud Rate 19.2. 4. Transfer the system block into the CPU. Switch the CPU back into RUN mode. Restart the CPU 315-2DP. 5. Check the communication by opening the status chart. Enter VB5000. The value VB5000 must behave like a clock marker. Charged software (payment by SIMATIC Card):The example contains both the STEP 7 V5 and the Micro/WIN 32 V3 hardware and communications configuration as described above. 5 / 5文档可自由编辑打印
