9.10.3 CONFIG mode
After constructing the CC-Link/LT system, execute the CONFIG mode to automatically assign the I/O
numbers.
(After constructing the CC-Link/LT system, assign the I/O numbers by executing the CONFIG mode.)
The FX
3UC-32MT-LT built-in master acquires the information (I/O type and number of points) on the
connected remote stations, then stores it to the buffer memory [BFM #32 (20h) to #95 (5Fh)] and built-in
memory (EEPROM).
If remote stations are to be extended in the future, the I/O numbers can be assigned while skipping some I/O
numbers.
→ For details on assignment of the I/O numbers, refer to Section 9.11.
1. Contents indicated by status indicator LEDs and countermeasures
The table below shows the descriptions of errors indicated by the status indicator LEDs and their
countermeasures.
2. Caution on editing the detailed remote station information
In the CONFIG mode, the L ERR. indicator LED turns on or starts to flicker when the detailed remote station
information becomes inconsistent with remote stations connected at the time of power ON due to a change in
the detailed remote station information.
If the power is set to ON while all remote stations are unconnected or if the remote stations are disconnected
after the power is set to ON, the L ERR. indicator LED will not turn on or start to flicker as long as the detailed
remote station information is not edited.
3. Caution with CONFIG mode
The ERR LED is lit while the power is ON in the CONFIG mode (DIP switch 6: ON, DIP switch 7: OFF), but it
does not indicate an error.

• Make the detailed remote station information
consistent with the connected remote I/O station
and remote device station.
• Confirm that the remote device station number is
within the allowable range.
