TP (pulse timing)

On a rising edge, the TP instruction increases an internal timer up to a given value. If the timer is elapsed, the internal time is reset.
Operation details: If the EN parameter is used with TP, the timer starts incrementing when EN is set to TRUE, and continues to increment even if EN is set to FALSE.
Languages supported: Function block diagram, ladder diagram, structured text.
