7. Various Modes
The FX
2N
-64CL-M has ONLINE, CONFIG and TEST modes.
Each mode can be selected using the appropriate DIP switch.
(Turn OFF the power to the PLC before setting the DIP switches.)
7.1 ONLINE mode (DIP switch bit 6 = OFF, bit 7 = OFF)
In ONLINE mode, the FX
2N
-64CL-M will execute the data link in the CC-Link/LT system.
Select this mode for normal use.
7.2 CONFIG mode (DIP switch bit 6 = ON, bit 7 = OFF)
In CONFIG mode, the FX
2N
-64CL-M assigns the station No. and I/O Nos. for remote stations.
The FX
2N
-64CL-M 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).
After constructing the CC-Link/LT system, execute the CONFIG mode to automatically assign
the I/O Nos.
(After constructing the CC-Link/LT system, assign the I/O Nos. by executing the CONFIG
mode.)
If remote stations are to be extended in the future, the I/O Nos. can be assigned while skipping
some I/O Nos.
For the details of assignment of the I/O Nos., refer to "8. Assignment of I/O Nos."
7.3 TEST mode (self-loop-back test) (DIP switch bit 6 = OFF, bit 7 = ON)
In TEST mode (for the self-loop-back test), the FX
2N
-64CL-M checks whether it is fully
functional by receiving data sent by itself.
In this test, it is not necessary to connect remote stations.
(Connect the FX
2N
-64CL-M to the power adapter, then turn ON the communication power.)
For details on the self-loop-back test, refer to "12.4 Self-loop-back test".
• When the FX
2N
-64CL-M is set to the TEST mode while it is connected to a FX
1N
Series
PLC, the PLC is stopped.
(The self-loop-back test will be executed normally, and the test result will be indicated by the
status indicator LEDs.)
