7.23 Miscellaneous Block - Timer
The timer block is a modified version of the
threshold block. Instead of monitoring a
parameter as the threshold block does, a timer is
monitored. When the timer exceeds the threshold,
a switch position is toggled, sending selected
levels to the output.
Timer Reset (311)
This parameter resets and holds the timer at 0 when True. A False value enables the timer
and counting begins. The timer range is 0.0 to 240.0 seconds.
Timer Invert (365)
Normally, when the
Timer Reset signal is True (any non-zero value), the timer is in the reset
and hold mode. The Invert parameter can be used to invert the logic, so that a False value
causes the timer to reset and hold.
Timer Threshold (312)
The value that the
Timer must count up to before the switch toggles.
Timer (428)
The value of the Timer.
Timer Greater Than (314)
When the timer is greater than the
Threshold , this value is sent to the Output .
Timer Less Than or Equal (313)
When the timer is less than or equal to the
Threshold
, this value is sent to the
Output
.
Timer Output (315, Read-Only)
Contains either the
Greater Than or Less Than or Equal values depending on the
comparison between the timer and the Threshold .
