1.1 Input Function
Number of input ON times alarm detection notification
To use the number of input ON times alarm detection notification, set "Number of input ON times alarm detect setting" to "To
detect" and set "Number of input ON times alarm detect count setting".
When the number of input ON times reaches the number of input ON times alarm detection count (set value), an alarm
(Number of input ON times alarm detection count reached) occurs.
The details of the alarm can be checked in the module diagnostics window of the engineering tool.
The alarm occurrence can be checked with the ALM LED.
In the following cases, an alarm occurs immediately.
• When the number of input ON times has already reached the number of input ON times alarm detection
count at power-on
• When a value equal to or less than the current number of input ON times is set as the number of input ON
times alarm detection count
■
Clearing an alarm
Although the number of input ON times is cleared to 0, an alarm is not cleared. To clear the alarm, turn on and off 'Alarm clear
request' (Y11) after clearing 'Number of input ON times' (Un\G2848 to Un\G2879).
