Description Note
(Bit)
EN 1: Activates the function block.
RE 1: Sets the actual time of the interrupt function
block back to the time at PD.
ST 1: Stops the interrupt function block's time meas-
urement.
0: The interrupt function block's time meas-
urement will continue.
I1 The states of the bit inputs from the main pro-
gram are provided to the interrupt program.
