The S7-200 can connect to a PROFIBUS network as a slave. You will need an EM277 module. All you need to do with this is to set the node address on the rotary switches. Everything else is configured by the PROFIBUS MASTER. The S7-200 system manual has an excellent section on this. http://support.automation.siemens.com/WW/view/en/1109582 |

Hi Apart from prevoius post here you can download the S7200 Sample Project for Profibus Configuration. https://www.automation.siemens.com/microset/html_76/support/tipps/tt-kommunizieren.htm Check the last tip "How to Connect an S7-300 (Master) to an S7-200 (Slave) by Means of PROFIBUS (Tip 57)" It explains in details about how to configure & program the S7 200 with Profibus. I hope it is useful for you. |

According to me CPU 200 does not support Profibus communication. You will have to use some external convertor as recommended by other posts. Paresh |

Paresh, I am sorry to disagree with you. S7-200 does support Profibus but only as a slave using EM277. https://mall.automation.siemens.com/DE/guest/content.asp?display=B&aktTab=1&lang=en&nodeID=10030268 So if SAIA PG2 is a DP master, it is possible to do this. But if SAIA PG2 is a DP slave then it not directly possible. But it will be possible to do some data exchangethrough a 3rd device as DP master. |
