Internode Test Start Switch (Bit 1)
Internode testing is executed and stopped by turning ON and OFF this switch.
The parameters for designating the remote node for testing, and so on, are set in
the allocated words in the DM Area. For details, refer to 9-3 Internode Test. The
CX-Programmer can also be used to set parameters and control internode tests.
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 oc-
cur. After all sockets have been force-closed, the Ethernet Unit will turn the
switch OFF again. Do not attempt to forcibly manipulate this switch before it is
automatically turned OFF by the Unit.
Ports used exclusively by the Ethernet Unit will not be closed.
Mail Send Switch (Bit 3)
User mail can be sent by turning ON this switch. The contents of the user mail
are set in the CPU Bus Unit System Setup.
After the user mail has been sent, the Ethernet Unit will turn this switch OFF
again. Do not attempt to forcibly manipulate this switch before it is automatically
turned OFF by the Unit.
