6.2.6 If Expected Output Is Not Available

■
Condition:
Both software reasons (e.g. program, I/O allocation) and hardware reasons (e.g. wiring, power
supply) are possible.
■
Solution (check of the output side)
Proceed from the check of the output side to the check of the input side.
1.
Check if the output indication LED on the input/output units is on.
If it is on, proceed to the next step. If it is not, proceed to Step 4.
2.
Check the wiring of the load (e.g. are there any loose terminals?).
If LED on the unit turns on following the above step, undercapacity of power supply is
possible. Review the power supply design.
3.
Check if the power is properly supplied to both ends of the load.
If the power is properly supplied to the load, there is probably an abnormality in the load. If
the power is not supplied to the load, there is probably an abnormality in the output section.
4.
Monitor the output status using the tool software FPWIN GR7.
If the output monitored is turned on, there is probably a duplicated output error, etc.
5.
Forcibly turn on and off the relevant output using the forced input/output functions of the
tool software FPWIN GR7.
If the output indicator LED of the units is turned on, go to input condition check. If the output
indicator LED remains off, there is probably an abnormality in the unit's output part.

Solution (check of the input side)
