Hello!

I have a Siemens PLC 1214C with MB_Server v2.0 (Instruction v3.1) block for the Modbus TCP connection (screenshot 1). Tag 10 is used for manual disconnect. The Modbus client is communicating with the PLC and exchange data. After 1 hour or after 2 days (always different time), the client loses the connection and the data exchange stops. In the data block of MB_Server on the PLC, the following information (screenshot 2). In this case, connection error does not occur at the output of the block. This problem is solved only by forced manual disconnect. How can I solve this problem?
