1.6.3Confirming the communication state to each station (Station monitoring function)
The station monitoring function detects the faults (communication timeout) of the stations monitored by the GOT. When detecting the abnormal state, it allocates the data for the faulty station to the GOT special register (GS).
(1) No. of faulty stations
(a) Ethernet connection (Except for Ethernet multiple connection) Total No. of the faulty CPU is stored.
