Limit Limit Limit Limit value value value value of of of of OT OT OT OT
The value of the operating hours in OT are retained when you reset the hours counter with a
signal at input R. The hours counter OT continues the count as long as En = 1, irrespective of
the status at the reset input R. The counter limit of OT is 99999 h. The hours counter stops
when it reaches this value.
In programming mode, you can set the initial value of OT. The counter starts operation at any
value other than zero. MN is automatically calculated at the START, based on the MI and OT
values.
Example: MI = 100, OT = 130, the result is MN = 70
Parameter Parameter Parameter Parameter preset preset preset preset
In xLogicsoft, you can define MI and an OT start value.
You determine that Q does not depend on En by selecting the corresponding check box.

The hours counter in the xLogic is generally retentive.
However, if the values of the hours counter are lost after a power failure, then select the
respective block in your circuit program. Right mouse click on the hours counter and select
