Limit value of 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 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.
Retentivity with the hours counter
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 Block Properties > Parameters. The option Retentivity must be activated and not
changeable (grayed out).
If the Retentivity option is not available, then delete the block and insert a new special
function
hours counter at the same position.
