Bit
b0 Data link status
b1 Initial communication status
b2 RUN status
b3 CONFIG mode
b4 EEPROM write completion
b5 Data link stopped
b6 to b15
Initial communication:
When the power to the PLC is set to ON, the PLC acquires information on connected remote stations from the
built-in master.

Function
Remains ON while the I/O image in the built-in master is updated by the
data link.
Turns ON when acquisition of the remote station information is
completed.
Remains ON while the unit is operating normally.
(Indicates the same contents as the LED.)
Remains ON while CONFIG mode is selected.
Turns ON when write to the EEPROM is completed, then turns OFF
when write is completed and the write request flag [BFM #27 (1Bh) b4]
is set to OFF.
Remains ON while the data link is stopped by the request to stop data
link.

Description
Turns ON when link error has occurred in
some stations. [Turns ON when any bit in
BFM #4 (4h) to 7 (7h) have turned ON.]
For the station number in which the error has
occurred, refer to the link error station
information [BFM #4 (4h) to 7 (7h)].
Turns ON when data link error has occurred
in all stations.
Turns ON when remote I/O error has
occurred. [Turns ON when any bit in BFM #8
(8h) to 11 (Bh) have turned ON.]
For the station number, refer to the remote
I/O error information [BFM #8 (8h) to 11
(Bh)].
For the type of error, refer to the instruction
manual of the appropriate remote station.
Turns ON when a remote station not
registered in the detailed remote station
information [BFM #32 (20h) to #95 (5Fh)] is
connected to the network.
Turns ON when the transmission speed
setting DIP switch is set to an incompatible
position.

Error flag restoration operation
When the cause of the error is eliminated,
the error flag is automatically restored.
When the cause of the error is eliminated,
the error flag is automatically restored.
When the cause of the error is eliminated,
the error flag is automatically restored.
If the station number of the connected
remote station is smaller than the final
station number, the error flag is
automatically restored when the cause of
the error is eliminated.
If the station number of the connected
remote station is larger than the final
station number, the error flag is restored
when the cause of the error is eliminated
and is followed by a power reset.
When the cause of the error is eliminated,
and power is reset, the error flag is
automatically restored.
