8-7
8.5 Editing the detailed remote station information
After assigning the I/O numbers in the CONFIG mode, the I/O number assignment in each
station number can be edited.
With this function, the number of I/O points can be changed, and the I/O numbers can be
assigned to unconnected station numbers for future use. If remote stations are added in the
future, it is not necessary to change the I/O numbers in other remote stations and extension
blocks/units connected to the PLC.
If a remote station is not connected to an edited station number, errors such as wire breakage
error will occur.
If a remote station is connected to an edited station number the remote station will operate with
the existing setting.
8.5.1 How to edit detailed remote station information
Edit the detailed remote station information using the steps 1) to 4) below.
1) Set the FX
2N
-64CL-M to the CONFIG Mode (by setting bit 6 of the DIP switch to ON and
setting bit 7 to OFF). Set the power of the FX
2N
-64CL-M to ON.
(The FX
2N
-64CL-M will assign the I/O numbers.)
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 OFF in the appropriate BFM.
(If the bit for reserved station is set to ON, the station is regarded as a reserved one, and
errors such as wire breakage error cannot be detected.)
3) To the detailed remote station information on every remote station to be edited, write the
information on the remote station. Then, give the instruction for write to the EEPROM [by
setting b4 of the BFM #27 (1Bh) from OFF to ON].
4) After editing the remote station information, confirm that write to the EEPROM is completed
by checking b4 of the BFM #28 (1Ch). Then, set the power of the FX
2N
-64CL-M to ON using
the normal procedure (by setting bit 6 of the DIP switch to OFF), and confirm that the
detailed remote station information [BFM #32 (20h) to BFM #95 (5Fh)] is updated.
