Operating Instructions, 06/2014
Depending on your configuration of the Q parameter, the output is either reset with a reset
signal at input R or Ral ("Q → R"), or when the reset signal is 1 or the En signal is 0 ("Q →
R+En").
Viewing the MI, MN and OT values
In LOGO!Soft Comfort you can fetch the hours counter via the Tools -> Transfer -> Hours
Limit value of OT
The value of the operating hours in OT is retained when you reset the hours counter with a
signal at input R. The hours counter OT will be reset to zero with a transition from 0 to 1 at
Ral. 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. MN is calculated according to the
In programming mode, you can set the initial value of OT. MN is calculated according to the
following formula when reset input R is never enabled: MN = MI - (OT % MI). The % operator
provides an integer division remainder.
Example:
MI = 30h, OT = 100h
MN = 30 - (100 % 30)
MN = 30 -10
MN = 20h
Example:
MI = 30h, OT = 100h
MN = 30 - (100 % 30)
MN = 30 -10
MN = 20h
In runtime mode, the value OT cannot be preset. If the value for MI is changed, there would
be no calculation for the MN. MN would take on the value of MI.
Parameter preset
In LOGO!Soft Comfort, you can define MI and an OT start value.
You determine that Q does not depend on En by selecting the corresponding check box.

If the values of the hours counter are lost after a power failure, then select the respective
If the values of the hours counter are lost after a power failure, then select the respective
block in your circuit program. Right-click the hours counter and select Block Properties >
Parameter. The option Retentivity must be activated and unchangeable (grayed out).
