Explanation
The instruct
ion is used t
o 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.

The instruction OR# is connected to
a contact in parallel.

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 DVP-20PM series motion controller used will
blink. (C200~C255 are 32-bit counters.)
Example
When X1 is ON, Y0 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 is ON.
When X2 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 C235 and the 32-bit register (D201, D200), and the operation result is
not 0, M60 is ON.
