Appendix 3 List of Link Special Relay (SB) Areas
Description
Stores the CPU operation mode status of each station.
Off: CPU backup mode set for all stations
On: Separate mode
This relay is turned off when 0 is set for all the settings of 'Separate mode status in
redundant system' (SW01F4 to SW01F7).
When this relay is turned on, the status of each station can be checked with 'Separate
mode status in redundant system' (SW01F4 to SW01F7).
Depending on the link refresh timing, the update of 'Separate mode status in redundant
system' (SW01F4 to SW01F7) may be offset by one sequence scan.
(Conditions)
• This register is enabled when 'Baton pass error status of own station' (SB0047) is off.
When 'Baton pass error status of own station' (SB0047) is turned on (error), data prior
to error is held.
• Reserved stations and stations exceeding the maximum station number are ignored.
Stores the pairing setting status for each station.
Off: No pairing-set station
On: Pairing-set station exists
When this relay is turned on, the status of each station can be checked with 'Pairing
setting status in redundant system' (SW01F8 to SW01FB).
Depending on the link refresh timing, the update of 'Pairing setting status in redundant
system' (SW01F8 to SW01FB) may be offset by one sequence scan.
(Conditions)
• This register is enabled when 'Baton pass error status of own station' (SB0047) is off.
When 'Baton pass error status of own station' (SB0047) is turned on (error), data prior
to error is held.
• Reserved stations and stations exceeding the maximum station number are ignored.
Stores the CPU operation status (control/standby system) of each station.
Off: Control system CPU at all stations
On: Standby system CPU exists.
When this relay is turned on, the status of each station can be checked with 'Standby
system CPU status in redundant system (SW01FC to SW01FF).
Depending on the link refresh timing, the update of 'Standby system CPU status in
redundant systemn' (SW01FC to SW01FF) may be offset by one sequence scan.
(Conditions)
• This register is enabled when 'Baton pass error status of own station' (SB0047) is off.
When 'Baton pass error status of own station' (SB0047) is turned on (error), data prior
to error is held.
• Reserved stations and stations exceeding the maximum station number are ignored.
