6.2.2 Wiring check
Confirm the wiring between remote I/O units and external equipment.
Example of wiring check
The figure below shows an example in which the head I/O No. 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 and remote I/O units using the dedicated cables.
Set the transmission speed, point mode, station No., etc. using the DIP switches in the
FX
2N
-64CL-M and remote I/O units.
At this time, select the CONFIG mode in the FX
2N
-64CL-M (by setting bit 6 ON and setting
bit 7 OFF).
2) Supply power to the power adapter before the PLC unit.
3) When the acquisition of remote I/O unit 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 bit 6 OFF and bit 7 OFF). Supply power
to the power adapter before the FX
2N
-64CL-M. Then, execute step 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 No. 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.
