Dear Hilscher team
We are building a prototype to send gathered information from a S7 1500 PLC to netpi via Profinet.
The connection seems to work, both the PLC and the fieldbus node don’t show any error.
For first test we set up an output address (1 Byte) in the PLC and assign the first bit with a switch conntected to the PLC. But the information received with the fieldbus node never displayed the information sent and additionally the information read from the fieldbus node switches each time between 2 different values. We stopped sending from the PLC but the fieldbus node kept reading 2 different values. Then we tried to send one Byte to the PLC but it probably never came through, the fieldbus input node then stated 2 different values but still switching as mentioned before.
I have the feeling we are just missing some detail but we are struggling to find it.
Attached you can find some screenshots regarding the PLC and Netpi settings
Best regards
Michael
