Modbus RTU Server not responding after Client Disconnected

Open Alexccw74 opened this issue 3 years ago • 2 comments

After some series of testing, I realize that Modbus RTU Server (RS485 COM PORT) will not response after the initial connected client disconnected. I have tested with different Modbus POLL program.
The error code from the Read "Block with function 3 is time out". The connection status is "Connected". Is there anything wrong with my setup? image image Hope to get a response soonest.

Same problem. Stops when no transmission for longer than timeout period. Temporary solution: ReadTimeout = int.MaxValue

Thank you, that is a good hint. I will try to solve it with the next update.
