Operation The output (Q) is set to 1 when the input (IN) has been 1 for a time defined by the pulse
time input (PT). The output is set to 0, when the input is set to 0.
Elapsed time count (TE) starts when the input is set to 1 and stops when the input is set
to 0.
Example:
Inputs Input (IN): Boolean
Pulse time input (PT): DINT (1 = 1 µs)
Outputs Output (Q): Boolean
Elapsed time output (ET): DINT (1 = 1 µs)
TP
