27.4 Ethernet Connection
27.4.9 Checking for normal monitoring
4 Confirming 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 is confirming the response by executing a Ping command to the
faulty station.
The station monitoring state can be confirmed by using GOT internal device.
(1) Station monitoring state
(a) No. of faulty station (GS230)
Total No. of the faulty CPU are stored.
The station No. of faulty stations are stored to GS231 through GS238. ( (b)Faulty station
information (GS231 to GS238))
When monitoring GS230 on Numerical Display
When monitoring GS230 on Numerical Display, check [mask processing] with data
operation tab as the following.
For the data operation, refer to the following manual.
GT Designer2 Version Screen Design Manual
<Numerical Display (Data Operation tab) >
Device b15 to b8 b7 to b0
GS230 (00H fixed) No. of faulty stations
Set [mask processing] to the upper eight bits (b8
to b15) of GS230 on Numerical Display.
