Store Positive Differential (STRPD)
The Store Positive Differential instruction begins a new rung or an
additional branch in a rung with a contact. The contact closes for one
CPU scan when the state of the associated image register point makes
an Off-to-On transition. Thereafter, the contact remains open until the
next Off-to-On transition (the symbol inside the contact represents the
transition). This function is sometimes called a “one-shot”. This contact
will also close on a program-to-run transition if it is within a retentative
range.
Store Negative Differential (STRND)
The Store Negative Differential instruction begins a new rung or an
additional branch in a rung with a contact. The contact closes for one
CPU scan when the state of the associated image register point makes
an On-to-Off transition. Thereafter, the contact remains open until
the next On-to-Off transition (the symbol inside the contact represents
the transition).
