Logic Solver Retentive Timer function block

The LSRET function block generates a True (1) discrete output after the input has been True for a specified time period. The time for which the input has been True and the output value are reset only when the reset input is set True.

IN_D is the discrete input value and status to be timed.

RESET_IN is the discrete input value and status used to reset OUT_D and ELAPSED_TIMER.

OUT_D is the discrete output value and status.

 

The following figure shows the internal components of the LSRET function block:
