and sets a configured value MI at the counter for the
duration of the time-to-go (MN).
Input En En En En En is the monitoring input. xLogic scans the on-time of this
input.
Input Ral Ral Ral Ral A positive edge at input Ral (Reset all) resets both the hours
counter (OT) and the output, and sets the configured value
MI at the counter to for the duration of the time-to-go (MN).
That is,
•
Output Q = 0,
•
The measured operating hours OT = 0, and
•
The time-to-go of the maintenance interval
MN = MI.
Parameter MI
MI MI
MI : Maintenance interval to be specified in hour units
Range of values: 0000...9999 h
OT OT OT OT : Expired total operation time. An offset can be specified.
Range of values: 00000...99999 h
Q Q Q Q 0:
•
When "R" is selected:
Q = 1, if MN = 0;
Q = 0, if R = 1 or Ral = 1
•
When "R+En" is selected:
Q = 1, if MN = 0;
Q = 0, if R = 1 or Ral = 1 or En = 0.
Output Q
Q Q
Q The output is set when the time-to-go MN = 0. The output is
reset:
•
When "Q 0:R+En", if
R = 1 or Ral = 1 or En = 0
•
When "Q 0:R",
if R = 1 or Ral = 1.
