TP / TPR![This function or function block supports PLCopen motion PLCopen motion icon](../Resources/Images/Icon_PLCopen.png)
A function block groups an algorithm and a set of private data. It has inputs and outputs. - Pulse
When the step gets activated, the action is activated for a single execution, and possibly once again when the step is deactivated timer.
Inputs
IN : BOOL Timer command
PT : TIME Programmed time
RST : BOOL Reset (TPR only)
Outputs
Q : BOOL Timer elapsed output signal
ET : TIME Elapsed time
Time diagram
Remarks
The timer starts on a rising pulse of IN input. It stops when the elapsed time is equal to the programmed time. A falling pulse of IN input resets the timer to 0, only if the programmed time is elapsed. All pulses of IN while the timer is running are ignored. The output signal is set to TRUE while the timer is running.
TPR is same as TP but has an extra input for resetting the timer
In FFLD language, the input rung is the IN command. The output rung is Q the output signal.
