CPU RUN status of each
station
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)
When some stations are in the STOP or PAUSE status, each
station status can be checked in CPU RUN status of each station
(SW0084 to SW0087).
Depending on the timing of the link refresh, CPU RUN status of
each station (SW0084 to SW0087) and the update may be offset
by one sequence scan.

SB0085
(133)
CPU RUN status of the
remote master station
Indicates the CPU run status of remote master station.
Off: Run or STEP RUN status
On: STOP or PAUSE status

SB0088
(136)
CPU operation status of
each station (2)
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
If any station with a minor error exists, the status of each station
can be checked in CPU operation status of each station (2)
(SW0088 to SW008B).
Depending on the timing of the link refresh, CPU operation status
of each station (2) (SW0088 to SW008B) and the update may be
offset by one sequence scan.

External power supply
information
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
When any station with external power supply exists, the status of
each station can be checked in Power supply status of each
station (SW008C to SW008F).
Depending on the timing of the link refresh, Power supply status
of each station (SW008C to SW008F) and the update may be
offset by one sequence scan.

Indicates the status of stations connected to the forward loop.
Off: All stations normal
On: Faulty stations exist
When any faulty station exists, the status of each station can be
checked in Forward loop status of each station (SW0091 to
SW0094).
Depending on the timing of the link refresh, Forward loop status
of each station (SW0091 to SW0094) and the update may be
offset by one sequence scan.
