Description
Indicates the operation status of each station's CPU on the PLC-
to-PLC network (including the host station).
Off: All stations abnormal
On: A moderate or serous error identified
This relay turns off when all of SW0080 to SW0083 are "0."
Indicates the operation status of each remote I/O station on the
remote I/O network (including the host station).
Off: All stations normal
On: Error station identified
This relay turns off when all of SW0080 to SW0083 are "0."
Indicates the CPU RUN status of each station.
Off: All stations are in the RUN or STEP RUN status
On: Stations in the STOP or PAUSE status exist
(including the host)
Turns off when the SW0084 to SW0087 are all "0."
Indicates the CPU run status of remote master station.
Off: Run or STEP RUN status
On: STOP or PAUSE status
Indicates the CPU status of the multiplexed remote sub-master
station.
Off: RUN or STEP RUN status
On: STOP or PAUSE status
Indicates the operation status of each station's CPU or of each
remote I/O station (including the host station).
Off: All stations normal
On: Stations with minor errors exist
Turns off when the SW0088 to SW008B are all "0."
Indicates the information of the external power supply (including
the host).
Off: All stations are without external power supply
On: Stations with external power supply exist
Turns off when the SW008C to SW008F are all "0."
Indicates the module type of each station.
Off: All stations are NET/10 type modules
On: NET/10H type modules exist
Indicates the host's loop status.
Off: Normal
On: Abnormal
Turns off when the SW0090 is all "0."
Indicates the status of stations connected to the forward loop.
Off: All stations normal
On: Faulty stations exist
Turns off when the SW0091 to SW0094 are all "0."
Indicates the status of stations connected to the forward loop.
Off: All stations normal
On: Faulty stations exist
Turns off when the SW0091 to SW0094 are all "0."
Indicates the status of stations connected to the reverse loop.
Off: All stations normal
On: Faulty stations exist
Turns off when the SW0095 to SW0098 are all "0".
Indicate the reverse loop status of the remote master station.
