Socket Services
Section 6-6
Ethernet Service Request
Socket Force-close Switch (Bit 2)
All UDP and TCP sockets used for socket services can be force-closed by turn-
ing 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 manipulate this switch before it is auto-
matically turned OFF by the PLC.
Ports used exclusively by the Ethernet Unit will not be closed.
