A TCP connection was established between SIMOTION D & S7-300(CP343-1),
the S7-300 was server. The system function : _tcpopenclient _tcpsend _tcpcloseconnection were used(Background task). And data was transfered successfully.
I turn off the PLC' power,then turn on the power. and the connection can't be established.
Enable _tcpcloseconnection ，then enable _tcpopenclient again, a new connection can't be established,either.
It seems only if you restart the SIMOTION'CPU, the connection become normal.
How to make SIMOTION D reestablish the TCP connection automatically in condition of PLC power off then power on?
