Timing diagram
MI = Configured time interval
MN = Time-to-go
OT = Total time expired since the last 1 signal at the Ral input
These values are principally held retentive!
Parameter
The maintenance interval MI can be provided by the actual value of another already-programmed
function:
Analog comparator: Ax – Ay
Analog trigger: Ax
Analog amplifier: Ax
Analog multiplexer: AQ
Analog ramp: AQ
Analog math: AQ
PI controller: AQ
Data latching relay: AQ
Up/Down counter: Cnt
The value of ＂ＭＩ＂ can be set and modified in parameter mode. For information about how to modify,
refer to chapter 4.2.2 please.
Description of the function
The hours counter monitors input En. As long as the status at this input is 1, xLogic calculates the time
expired and the time-to-go MN. xLogic displays these times when set to configuration mode. The output
is set to 1 when the time-to-go is equal to zero.
You reset output Q and the time-to-go counter to the specified value MI with a signal at input R. The
operation hour counter OT remains unaffected.
