I have a s7-200 connected to a tp177 micro.My problem is that i cannot switch on an output on the s7-200 with the tp177.The tp177 can read if an output or input is on from the s7-200.I have used the same method when i used the C7-635 and the s7-300 and it worked.I don't know why it won't work.Do u guys have any suggestions?
