Hello Armin,
I'm still working on my project to read/write data with the netpi from an S7-1500 plc with Profinet using node-red.
At the start, I had these problems which i posted here. Your information was very helpfully so I finished the first part of my project. I was able to read/write data from the S7 with the fieldbus nodes and everything worked fine.
A few days ago, I had to reinstall the netPI. I installed the docker container netPI-nodered-fieldbus as I did it the first time. But now I'm not able to read or write the profinet signal. The output gives me some values which doesnt make sense. I did everything as before time but it doesnt work. So i thought maybe there is a new version of netPI-nodered-fieldbus on GitHub. 14 days ago, there was a update for these container. maybe something is wrong with that? could you check it? I cannot explain why my implementation should be wrong, everything is as before when it worked.
Thank you very much!
Best regards,
Marcel
