Or Bit-of-Word (ORB)
The Or Bit-of-Word instruction logically ors a
normally open Bit-of-Word contact in parallel with
another contact in a rung. Status of the contact will be
the same state as the bit referenced in the associated
memory location.
Or Not Bit-of-Word (ORNB)
The Or Not Bit-of-Word instruction logically ors a
normally closed Bit-of-Word contact in parallel with
another contact in a rung. Status of the contact will be
opposite the state of the bit referenced in the associated
memory location.
In the following Or Bit-of-Word example, when input X1 or bit 7 of V1400 is on, output Y7
will energize.
In the following Or Not Bit-of-Word example, when input X1 is on or bit 7 of V1400 is off,
