And Positive Differential (ANDPD)
The And Positive Differential instruction logically ands
a normally open contact in series 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.
And Negative Differential (ANDND)
The And Negative Differential instruction logically ands
a normally open contact in series with another contact
