Appendix 3 List of Link Special Relay (SB)
SB00A1 Baton pass error status of master
station Stores the baton pass status of the master station (master operating station).
Off: Normal
On: Error
(Conditions)
• This relay is 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.
SB00B0 Data link error status of each
station Stores the data link status of each station.
Off: All stations normal
On: Faulty station exists
When this relay is turned on, the status of each station can be checked with "Data link status of each station"
(SW00B0 to SW00B7).
Depending on the link refresh timing, the update of "Data link status of each station" (SW00B0 to SW00B7)
may be offset by one sequence scan.
If the master station is powered on before slave stations, data link may be reconfigured. During the
reconfiguration (maximum three seconds), "Data link error status of each station" (SB00B0) is turned on
(error). Starting up the master station last can prevent data link from being reconnected and "Data link error
status of each station" (SB00B0) from being turned on (error).
(Conditions)
• This relay is 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.
• Reserved stations and stations higher than the maximum station No. are ignored.
SB00B1 Data link error status of master
station Stores the data link status of the master station (master operating station).
Off: Normal
On: Error
(Conditions)
• This relay is enabled when "Baton pass status of own station" (SB0047) is off.

SB00B8 Network connection status of each
station Stores whether a network connected station exists.
Off: No network connected station
On: Network connected station exists
When this relay is turned on, the status of each station can be checked with "Network connection status"
(SW00B8 to SW00BF).

may be offset by one sequence scan.
(Conditions)
• This relay is enabled when "Baton pass status of own station" (SB0047) is off.

SB00D0 Error invalid station setting current
status Set whether an error invalid station is set.
Off: No setting
On: Set
When this relay is turned on, the status of each station can be checked with "Error invalid station setting
status" (SW00D0 to SW00D7).
Depending on the link refresh timing, the update of "Error invalid station setting status" (SW00D0 to
SW00D7) may be offset by one sequence scan.
(Conditions)
• This relay is 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.
SB00E0 Temporary error invalid station
setting status Stores whether a temporary error invalid station is set.

to SW00E7) may be offset by one sequence scan.
(Conditions)
• This relay is 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.
