Confirm the wiring between remote modules and external equipment.
Example of wiring check
The figure below shows an example in which the head I/O number in the FX
2N
-64CL-M is
X020/Y020 and 4-point mode is selected.
Operating procedure
1) Connect the FX
2N
-64CL-M, power adapter / dedicated power supply and remote modules
using cables, and then set the transmission speed, point mode, station number, etc. using
the DIP switches in the FX
2N
-64CL-M and remote modules.
At this time, select the CONFIG mode in the FX
2N
-64CL-M (by setting bit 6 ON and setting
bit 7 OFF).
2) Turn ON the power to the power adapter or dedicated power supply, and then turn ON the
power to the PLC.
3) When the acquisition of remote module information is completed in the CONFIG mode (that
is, when b4 of the BFM #28 (1Ch) turns ON), turn the power OFF.
4) Set the FX
2N
-64CL-M to ONLINE mode (by setting bits 6 and 7 to OFF in the DIP switch).
Turn ON the power again to the power adapter or dedicated power supply, and then turn ON
the power to the PLC. Perform the operation a) or b) below.
a) Checking the wiring between the input unit and external equipment
- Turn ON the switch corresponding to "X020" of the external equipment connected to
the input unit with station number is 1.
- Monitor X020 from peripheral equipment.
- If X020 is ON, connection between the input unit and external equipment is normal.
b) Check the wiring between the output unit and external equipment
- Turn Y020 ON/OFF from peripheral equipment using the forced ON/OFF operation.
- If the connection between the output unit and external equipment is normal, a lamp
corresponding to "Y020" in the external equipment will light.
