9	ORB
10 OUT		Y	4

Basic points to remember:

-Use the ORP and ORF instructions for the parallel connection of pulse contacts.

-Usage is the same as for OR and ORI; see earlier.

-ORP is active for one program scan after the associated device switches from OFF to ON.

-ORF is active for one program scan after the associated device switches from ON to OFF.

Single operation flags M2800 to M3071:

• When used with flags M2800 to M3071 only the first instruction will activate. For details see page 2-8
