Countermeasures based on detailed error information

The contents of error flags indicated by the BFM #29 (1Dh) and countermeasures against
them are as shown below.
Bit
Turns ON when link error has occurred in
some stations. [Turns ON when either or
some bits among BMF #4 (4h) to 7 (7h) have
b0 turned ON.]
For the station No. in which error has
occurred, refer to the link error station
information [BFM #4 (4h) to 7 (7h)].
Turns ON when data link error has occurred
b1
in all stations.
Turns ON when remote I/O error has
occurred. [Turns ON when either or some
bits among BMF #8 (8h) to 11 (Bh) have
turned ON.]
b2
For the station No., refer to the remote I/O
error information [BFM #8 (8h) to 11 (Bh)].
For the description of error, refer to the
instruction manual of each remote station.
Turns ON when a remote station not
registered in the detailed remote station
b3
information [BFM #32 (20h) to #95 (5Fh)] is
connected to the network.
Turns ON when the transmission speed
b4 setting DIP switch is set to an incompatible
position.
Turns ON when the power for communication
b5
is downed.
b6
Turns ON when EEPROM write error or read
error has occurred or when the request to
b7
write EEPROM is given in any mode other
than the CONFIG mode.

Countermeasures
Securely connect the FX
remote I/O units.
• Make the detailed remote station
information consistent with connected
remote I/O units.
• Confirm connection to the power adapter
and the power supplied to the power
adapter. (For the details of power adapter,
refer to the User's Manual (Detailed
Volume) of the power adapter.)
