b1 Initial communication status
Turns ON when acquisition of the remote station information is
completed.
b2 RUN status
Remains ON while the unit is operating normally.
(Indicates the same contents as the LED.)

Bit Function Description Error flag restoration operation
b0
Link error in
some stations
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)].
When the cause of the error is eliminated,
the error flag is automatically restored.
b1
Link error in all
stations Turns ON when data link error has occurred
in all stations. When the cause of the error is eliminated,
the error flag is automatically restored.
b2
Remote I/O
error
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.
When the cause of the error is eliminated,
the error flag is automatically restored.
b3
Out-of-
control-range
station error
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.
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.
b4
Transmission
speed setting
error Turns ON when the transmission speed
setting DIP switch is set to an incompatible
position. When the cause of the error is eliminated,
and power is reset, the error flag is
automatically restored.
