Description
Stores the path switching detection status of each station. (Including own
station)
OFF: Path switching not detected
ON: Path switching detected
When a path switching has been detected, each station status can be
checked in Path switching detection status of each station (SW0160 to
SW0167).
Depending on the link refresh timing, Path switching detection flag for each
station (SW0160 to SW0167) and the update may be offset by one sequence
scan.
The path switching detection status is cleared when Clear loop switching
counter (SB0009) is turned ON.
The stored value is cleared when Clear loop switching counter (SB0009) is
turned ON in each station and path switching detection status for all stations
is cleared.
(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 is held.
Stores the transient transmission error detection status of each station.
(Including own station)
OFF: Error not detected
ON: Error detected
When an error has been detected, each station status can be checked in
Transient error detection status of each station (SW0170 to SW0177).
Depending on the link refresh timing, Transient error of each station
(SW0170 to SW0177) and the update may be offset by one sequence scan.
The transient error detection status of own station is cleared when Clear
transient transmission error counter (SB000A) is turned ON.
The stored value is cleared when Clear transient transmission error counter
(SB000A) is turned ON in each station and the transient error detection
status for all stations is cleared.
(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 is held.
Stores the external power supply status of the CC-Link IE Controller Network

OFF: No external power supplied to any station
ON: External power supplied to station(s)
When external power is supplied to station(s), each station status can be
checked in Power supply status of each station (SW0180 to SW0187).
Depending on the link refresh timing, External power supply information
(SW0180 to SW0187) 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
