On PLC to PLC network
Indicates the setting of "With data link by sub control station
when control station is down."
Off: Cyclic transmission made by sub control station when
control station fails.
On: Cyclic transmission not made by sub control station
when control station becomes faulty
On remote I/O network
Indicates the status of designating cyclic transmission when the
(multiplexed) remote master station fails.
Off: Cyclic transmission made by multiplexed remote sub-
master station when multiplexed remote master station
fails (multiplexed remote I/O network)
On: Cyclic transmission not made when remote master
station fails (remote I/O network)
Indicates whether or not there are any parameter settings for the
low-speed cyclic transmission.
Off: No settings
On: Settings exist
Indicates the parameter type of the control station.
