
The instruction is used to compare the value in S
1
with that in S
2
. If the
comparison result is not 0, the condition of the instruction is met. If the
comparison result is 0, the condition of the instruction is not met.


If a 32-bit counter is used, the 32-bit instruction DOR# must be used. If a
32-bit counter and the 16-bit instruction OR# are used, a program error
will occur, and the ERROR LED indicator on the motion control module
will blink. (C200~C255 are 32-bit counters.)


When X0.1 is ON, Y0.0 is ON. Besides, when a logical AND operator
performs the logical AND operation on each pair of corresponding bits in
C0 and C10, and the operation result is not 0, Y0.0 is ON.

When X0.2 and M30 are ON, M60 is ON. When a logical OR operator
performs the logical OR operation on each pair of corresponding bits in
the 32-bit register (D11, D10) and the 32-bit register (D21, D20), and the
operation result is not 0, M60 is ON. Besides, when the logical XOR
operator performs the logical exclusive OR operation on each pair of
corresponding bits in the 32-bit counter C2350 and the 32-bit register
(D201, D200), and the operation result is not 0, M60 is ON.
