3.2.8 Supervision and Control Port.
SSE232-LE incorporates the possibility to administer digital inputs/outputs and to supervise the
status of the 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 if each command has been successfully executed of not.
3.2.8.1 Supervision of Connections Commands
You may supervise the connections by executing the STA and RST commands.
The
STA
command will allow you to know the status of the connection 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”.
