i have got a Problem and Maybe you could help me with that. The Problem is that I started node-red and my Connection with the PLC does work. So it says it is online. But it always says too, that no Response from PLC, try connecting again. I tried this first with another SPS and there it went with the new SPS it does not go any more. The first PLC was a CPU 1516-3 PN/DP from Siemens and the second one is also a 1513-1 PN from Siemens. It´s the same Program.
I dont know what I should do. And I hope it is understandable.
Thank you in Advance for your answer.
