3. CONFIG mode (Cautions on use)
In CONFIG mode, if the detailed remote station information [BFM #32 (20h) to #95 (5Fh)] is edited, and if the
detailed remote station information is inconsistent with remote stations actually connected at the time of
power ON as a result of the editing, there will be a data link error.
(When BFM #32 (20h) to #95 (5Fh) is edited, the station numbers are checked.)
If the power is set to ON while all remote stations are unconnected or if remote stations are disconnected
after the power was set to ON, data link error is not detected, as long as the detailed remote station
information is not edited.

9.18.3 Remote I/O error information [BFM #8 (8h) to #11 (Bh)]

The remote I/O error occurrence status is stored here. (Bits for stations with I/O error are ON.)
For the type of error, refer to the instruction manual of each remote station.
1. Detailed description
The station number of each remote station is assigned to each bit of the buffer memory [BFM #8 (8h) to #11
(Bh)]. The absence/presence of remote I/O errors are indicated by the 0 (OFF)/1 (ON) status of each bit.

1. Detailed description
The station number of each remote station is assigned to each bit of the buffer memory [BFM #16 (10h) to
#19 (13h)]. Whether or not a station is specified as reserved is indicated by the 0 (OFF)/1 (ON) status of each
bit.
