Selection of operation mode and operation location
When switching between the network operation mode and external operation mode:
Set Pr. 79 to "0" (initial value), "2", "6" or "7". (At the Pr. 79 setting of "7", the operation mode
can be switched when the X12 (MRS) signal turns on.)
Set "0" (initial value), "1" or "2" in Pr. 340 "Communication start-up mode selection".
Set "66" to any of Pr. 178 to Pr. 189 to assign the external-NET operation switching signal
(X66) to the external terminal.
The operation mode changes to network operation mode when the X66 signal turns on, or
to external operation mode when the X66 signal turns off.
