20.2 What to Do If an Error Occurs
20-9
4. Use the tool software to monitor the input status.
If the monitor state is OFF, it may be due to an abnormal unit input.
If the monitor state is ON, recheck the program. When the input device is two-wire
sensor, it may be caused by a leakage current.
KEY POINTS
•
When rechecking the program, note the following items.
1. Check if the output has been rewritten, for example, a dual output is used.
2. Check if the program process has changed via control instructions such as MCR
and JMP instruction.
3. Check if the allocation of the I/O mapping is consistent with the installation state.
20.2.7 When Expansion Units are Not Operated
Situation
The setting of the expansion unit may be incorrect.
PROCEDURE
1. Verify if the expansion unit terminal is set correctly.
Verify if the terminal setting of several units is made.
2. Verify if the expansion FP0 adapter is attached to the end.
When the FP-X expansion FP0 adapter is attached to the end, the other
expansion unit does not need to be set in the terminal.
3. Verify if a momentary outage or other short time power on/off are occurred.
Sometimes, it is unable to identify the expansion unit due to momentary outage
and other short time power on/off. Reconnect the power.
