Redundant system information
The information related to the redundant system is stored.
■Setting status of system switching monitoring target station (Un\G24496 to Un\G24503)
The setting status of system switching monitoring target station of each station is stored. These areas can be used in a master
station only.
• 0: Station other than a system switching monitoring target station
• 1: System switching monitoring target station
Each number in the table represents a station number.
*1 "1" is stored when there is a system switching monitoring target station on the network.
■Redundant function information of each station (Un\G24504 to Un\G24511)
The redundant system support information of each station (including the own station) is stored.
This register is enabled only for normally operating stations in 'Baton pass status of each station' (SW00A0 to SW00A7).
Reserved stations and stations with a number equal to or greater than the maximum station number are ignored.
• 0: Redundant function not supported
• 1: Redundant function supported
Each number in the table represents a station number.
*1 "1" is stored when there is a redundant system station on the network.
*2 The redundant function support information of the master operating station is stored.
*3 The redundant function support information of the station No.0 is stored.
■Separate mode status of each station (Un\G24512 to Un\G24519)
The redundant system CPU operating mode of each station (including the own station) is stored.
This areas are enabled when 'Baton pass status of own station' (SB0047) is off. When 'Baton pass status of own station'
(SB0047) is turned on, data prior to error is held.
This register is enabled only for normally operating stations in 'Baton pass status of each station' (SW00A0 to SW00A7).
Reserved stations and stations with a number equal to or greater than the maximum station number are ignored.
"0" is stored for a station other than a redundant system station.
• 0: Backup mode
• 1: Separate mode
Each number in the table represents a station number.
*1 "1" is stored when there is a separate mode station on the network.
*2 The redundant system CPU operating mode of the master operating station is stored.
*3 The redundant system CPU operating mode of the station No.0 is stored.
