Hello, I've prepared this list of topics which can be helpful to you: Topics about S7-1200 serial communication problematic Some sugestions to your code screenshots. I expect maybe turn off Port cfg REQ after sucessful execution. Then you can continue with Send or Receive blocks, simply for first you can so configure port with some parameters required then you can data exchange. Logically, right? You have some string of 2 chars in buffer but LEN (length) what you want send is 10. Hope I good see that from your pictures. |
With best regards... |
