Unit Control Bits (CPU Unit to Ethernet Unit)
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 process-
ing.
Be careful not to force-close sockets during communications, or an error will
occur. 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 automati-
cally turned OFF by the Unit.
Automatic Clock Adjustment Switch (Bit 4)
The automatic clock adjustment can be executed by turning this switch ON.
The SNTP server required for the automatic clock adjustment is set in the Unit
Setup.
After the automatic clock adjustment has been completed, the Ethernet Unit
will automatically turn this switch OFF. Until then, do not forcibly manipulate
the switch.
