2) Write the information (station type and number of I/O points) for the station to be added in
the detailed remote station information buffers [BFM #32 (20h) to #95 (5Fh)]. Set the
reserved station flag (bit 15) to ON in the appropriate BFM.
(If the bit for reserved station is set to OFF, errors such as wire breakage are detected while
a remote station is not connected.)
3) Give the instruction to write to the EEPROM [by setting from OFF to ON b4 of the BFM #27
(1Bh)].
4) After setting reserved stations, confirm that write to the EEPROM is completed by checking
b4 of the BFM #28 (1Ch). Then, set the power of the FX
procedure (setting the bit 6 of the DIP switch to OFF), and confirm that the detailed remote
station information [BFM #32 (20h) to #95 (5Fh)] is updated.
