Supervision and Control Port.
The SSE232-IA allows to control digital inputs/outputs and to supervise the status of connection
sockets linked to every channel by simple commands.
The Supervision and Control Port works through a TCP connection in the port 999. Each command
must end with the CR character (ASCII 13).
The system will answer whether each command has been successfully executed.

You may supervise the connections by executing the STA

RST commands....
The
STA
command will allow you to know the connection status of a channel on the Ethernet
side by answering ‘1’ (Connected) or ‘0’ (Disconnected).
The
RST
command allows to reset the socket of a specified channel. If your command is related
to a socket of a channel that is not available on that model, the answer will be “error”.
