C.2 Timer and Counter Blocks
C.2.1 Timer, Pulse (TP)
When used in a Ladder Diagram, the TP block turns on the output state for a
fixed-width pulse.
Select the tool (from the Timers and Counters Blocks toolbar) and click on a
ladder rung to insert the following block:
Once the block is inserted, you can double-click on it to configure it.
Functional Description
When the Input State (IN) becomes on, the Output State (Q) is turned on and the
associated
Timer variable (TIMER) is started. When the Timer equals the Preset
Time input (PT), the Timer is stopped and Q is turned off.
When both IN and Q become off, the Timer is reset to 0.
The Timer cannot be stopped once it is started, even if IN becomes off before the
Timer equals PT.
The Elapsed Time output (ET) shows the time passed since IN became on; in other
words, it shows the current value of the Timer itself. When the Timer reaches PT,
ET remains equal to PT until it is reset. When the Timer is reset to 0, ET is reset to
0.
