I have an application I am converting from Allen Bradley code. In the Allen Bradley I am using the OSF block. This block has a storage bit and an output bit that retains state after the transition. I tried to use a -|N|- but the coil will not retain the state unless I make it a -(S)-. Then I have no easy way to reset it.

Is there a simple way to achive this same functionality in VisiLogic?

false-to-false bit is reset bit is reset

false-to-true and true-to-true bit is set bit is reset
