Description
Stores the CPU operation mode status of the stations (including the own
station).
OFF: No separate-mode station (including single systems)
ON: Separate-mode station exists.
If any station is in separate mode, each station's status can be checked by
Redundant system status (1) (SW01D0 to SW01D7).
Depending on the link refresh timing, Redundant system status (1) (SW01D0
to SW01D7) and the update may be offset by one sequence scan.
(Condition)
Valid when Baton pass status (own station) (SB0047) is OFF.
When Baton pass status (own station) (SB0047) is turned ON (error), data
prior to error are held.
Stores the pairing setting status of the stations (including the own station).
OFF: No pairing-set station
ON: Pairing-set station exists.
If any station has a pairing setting, each station's status can be checked by
Redundant system status (2) (SW01E0 to SW01E7).
Depending on the link refresh timing, Redundant system status (2) (SW01E0
to SW01E7) and the update may be offset by one sequence scan.
(Condition)
Valid when Baton pass status (own station) (SB0047) is OFF.
When Baton pass status (own station) (SB0047) is turned ON (error), data
prior to error are held.
Stores the CPU operating status (control/standby system) of the stations
(including the own station).
OFF: No standby system CPU station (including single systems)
ON: Station of standby system CPU exists.
If a station has a standby system CPU, each station's status can be checked
by Redundant system status (3) (SW01F0 to SW01F7).
Depending on the link refresh timing, Redundant system status (3) (SW01F0
to SW01F7) and the update may be offset by one sequence scan.
(Condition)
Valid when Baton pass status (own station) (SB0047) is OFF.
When Baton pass status (own station) (SB0047) is turned ON (error), data
prior to error are held.
