10.4.1 [BFM#10] Input signal details
1. Unit error (b0)
Indicates whether the unit is normal or not.
OFF: The unit is normal.
ON : The unit is abnormal.
2. Data link status in master station (b1)
Indicates the data link status in the master station.
OFF: Data link is stopped.
ON : Data link is in progress.
3. Parameter setting status (b2)
Indicates the parameter setting status in the master station.
The signal SB006D has the same meaning.
OFF: The setting is normal.
ON : There is an error in the setting. (The error code is stored in SW0068.)
This signal turns OFF when the write request for data link startup by buffer memory parameters (BFM#10 b6)
in which no error has occurred.
4. Data link status in other stations (b3)
Indicates the data link status at other stations (remote stations and intelligent device stations).
The signal SB0080 has the same meaning.
OFF: All stations are normal.
ON : There is an error in some stations. (The error station status is stored in SW0080.)
Caution
The other station data link status takes up to 6 seconds to turn on after a slave station connected to the
master station becomes faulty. The time to turn ON differs according to the system configuration, faulty status
or other conditions.
5. Normal completion of data link startup by buffer memory parameters (b6)
Indicates the normal completion status of the data link startup request by the write request for data link startup
by buffer memory parameters (BFM#10 b6).
1) When the write request for data link startup by buffer memory parameters (BFM#10 b6) is set to ON, the
contents of the buffer memory parameters are checked. When the contents are normal, the system
automatically starts data link.
2) When data link startup is normally completed, the read data link startup normal completion (BFM#10 b6)
turns ON.
3) When the write request for data link startup by buffer memory parameters (BFM#10 b6) is set to OFF, the
read normal completion of data link startup by buffer memory parameters (BFM#10 b6) turns OFF.
