I tested the protocoll of Motor and S7-1200 with Simulation Software.
My result is:
Motor is okay, write and read registers is possible, telegrams are okay
PLC: telegrams are the same as in master simulation software,
I can write registers in slave simulation
BUT: PLC can't read the response from slave. Thats why status got timeout.
I can't explain why??? Is there maybe a wrong setting in response time or waiting time or maybe in port configuration? I'm using RS485 port.
Can anybody help?
