The following table and descriptions cover the words and bits in the Auxiliary Area of PLC memory that
are related to the socket services.
z Socket Force-close Switch (Bit 2)
All UDP and TCP sockets used for socket services can be force-closed by turning ON this switch.
This can be used for operations such as error processing.
Be careful not to force-close sockets during communications, or an error will occur. After all sockets
have been force-closed, the PLC will turn the switch OFF again. Do not attempt to forcibly manipu-
late this switch before it is automatically turned OFF by the PLC.
Ports used exclusively by the Ethernet Unit will not be closed.
