I'm setting up my S7-1200 and two CM 1241 modules to communicate with two sensors. It was working for me a few days ago (link) but now it has completely stopped. I'm not sure what changed and it's driving me crazy. I then decided to reprogram everything following the example in the S7-1200 manual v4.5 section 13.3.7.3 It still does not work. Something is strange with RCV_PTP. I have attached a picture of the result:
I have an older PLC of a different brand that I previously programmed to communicate with these sensors. I can plug them in to that PLC and they both work fine, so I don't think the issue is with the sensors. Even if there was a problem with the sensors or a mistake in how I configured the ports, wouldn't I still get an RCV_PTP ERROR due to timeout or something else? No NDR and no ERROR is hard to understand. |
