A
SB00F8 Network number
match status Stores the network number match status of each station.
• OFF: Network number match in all stations
• ON: Network number mismatch station found
If a network number mismatch station is found, the status of each station can be
checked using Network number match status (SW00F8 to SW00FF).
Depending on the timing of the link refresh, the update of Network number match
status (SW00F8 to SW00FF) may be offset by one sequence scan.
 
SB0100 Operation status
(each station) (1) Stores the moderate/major error or stop error status of each station.
When the target station is the master/local module, the occurrence status on the
control CPU is stored.
• OFF: No moderate/major error (stop error)
• ON: Station with a moderate/major error (stop error) exists
If a station with a moderate/major error (stop error) is found, the status of each station
can be checked with Operation status (each station) (1) (SW0100 to SW0107).
Depending on the timing of the link refresh, the update of Operation status (each
station) (1) (SW0100 to SW0107) may be offset by one sequence scan.
(Conditions)
This is enabled when the Baton pass status (own station) (SB0047) is OFF.
 
SB0101 CPU operation
status (master
station) (1) Stores the stop error status of the master station's CPU module.
• OFF: Normal
• ON: Stop error occurred
(Conditions)
This is enabled when the Baton pass status (own station) (SB0047) is OFF.
 
SB0108 Station number
duplication
occurrence status Stores the station number duplication occurrence status of each station.
• OFF: No duplication of station number
• ON: Station number duplicated
If a station number is duplicated, the status of each station can be checked using
Station number duplication occurrence status (SW0108 to SW010F).
Depending on the timing of the link refresh, the update of Station number duplication
occurrence status (SW0108 to SW010F) may be offset by one sequence scan.
 
SB0110 Operation status
(each station) (2) Stores the minor error or continuation error status of each station.
When the target station is the master/local module, the occurrence status on the
control CPU is stored.
• OFF: All stations normal or station with a moderate/major error(stop error) exists
• ON: Station with a minor error (continuation error) exists
If a station with a minor error (continuation error) is found, the status of each station
can be checked by Operation status (each station) (2) (SW0110 to SW0117).
Depending on the timing of the link refresh, the update of Operation status (each
station) (2) (SW0110 to SW0117) may be offset by one sequence scan.
(Conditions)
This is enabled when the Baton pass status (own station) (SB0047) is OFF.
 
SB0111 CPU operation
status (master
station) (2) Stores the continuation error status of the master station's CPU module.
• OFF: Normal
• ON: Continuation error occurred
(Conditions)
This is enabled when the Baton pass status (own station) (SB0047) is OFF.

SB0120 PORT1 current error
frame reception
status (1) Stores if a receive frame error line status caution level has occurred in each station's
PORT1.
• OFF: A receive frame error line status caution level has not yet been occurred in
any stations.
• ON: A receive frame error line status caution level has been occurred in one or
more stations.
If a receive frame error line status caution level has been occurred, the status of each
station can be checked by PORT1 current error frame reception status (each station)
(1) (SW0120 to SW0127).
Depending on the timing of the link refresh, the update of PORT1 current error frame
reception status (each station) (1) (SW0120 to SW0127) may be offset by one
sequence scan.
(Conditions)
This is enabled when the Baton pass status (own station) (SB0047) is OFF.
