Hello Philippe; The freeport protocol appears to fill your requirements, and you can program freeport (Send_P2P, Receive_P2P instructions) with self-created strings. First here is a condensed presentation of Freeport instructions for a S7-1200.: https://www.dmcinfo.com/latest-thinking/blog/articletype/articleview/articleid/8297 For S7-1200 you will need a serial interface, CM 1241 or CB 1241, RS-485; for a S7-1500, you have a choice of CM PtP RS422/485 HF or CM PtP RS422/485 BA. The S7-1200 system manual describes PTP configuration and instructions ( see Send_P2P and Receive_P2P in the left navigation column) here: https://support.industry.siemens.com/cs/ww/en/view/109759862/96893760523 This video proesentation can probably guide you for this application. Even though the module used in the video is a CM 1241 RS 232, the instructions you would need are the same. Hope this helps, |

New question published by AutoGen_7376155 is split to a separate thread with the subject communication between PLC S71200 and ebm-papst fan via ebmBus protocol. Best regards |
