Off: Station number set
On: Station number not set
If parameters are set using the engineering tool, this relay is always
OFF.
SB0047 Baton pass status of own station Stores the baton pass status (transient transmission availability) of
the own station.
Off: Normal
On: Error
When this relay is turned on, the cause of the error can be checked
with 'Baton pass status of own station' (SW0047) and 'Cause of
baton pass interruption' (SW0048).
Depending on the link refresh timing, the update of 'Baton pass
status of own station' (SW0047) and 'Cause of baton pass
interruption' (SW0048) may be offset by one sequence scan.
SB0049 Data link error status of own station Stores the data link error status of the own station.
Off: Normal
On: Error
When this relay is turned on, the cause of the error can be checked
with 'Cause of data link stop' (SW0049). Depending on the link
refresh timing, the update of 'Cause of data link stop' (SW0049)
may be offset by one sequence scan.
(Conditions)
