Or Positive Differential (ORPD)
The Or Positive Differential instruction logically ors a
contact in parallel with another contact in a rung. The
status of the contact will be open until the associated
image register point makes an Off-to-On transition,
closing it for one CPU scan. Thereafter, it remains
open until another Off-to-On transition.
Or Negative Differential (ORND)
The Or Negative Differential instruction logically ors a
contact in parallel with another contact in a rung. The
status of the contact will be open until the associated
image register point makes an On-to-Off transition,
closing it for one CPU scan. Thereafter, it remains
open until another On-to-Off transition.
