Operands:
S
1
: Data source device 1 S
2
: Data source device 2
Explanations:
1. See the specifications of each model for the range of operands.
2. This instruction compares the content in S
1
and S
2
. If the result is not “0”, the continuity of the instruction is
enabled. If the result is “0”, the continuity of the instruction is disabled.
3. OR# (#: &, |, ^) is an operation instruction used on parallel contacts.

4. &: Logical “AND” operation
5. |: Logical “OR” operation
6. ^: Logical “XOR” operation
7. When 32-bit counters (C200 ~ C255) are used in this instruction for comparison, make sure to adopt 32-bit
instruction (DOR#). If 16-bit instructions (OR#) is adopted, a “program error” will occur and the ERROR
indicator on the MPU panel will flash.
Program Example:
1. When X1 = On and the result of logical AND operation of C0 and C10 ≠ 0, Y10 = On.
2. M60 will be On when X2 = On and M30 = On, or the result of logical OR operation of 32-bit register D10 (D11)
and 32-bit register D20 (D21) ≠ 0, or the result of logical XOR operation of 32-bit register D200 (D201) and
32-bit counter C235 ≠ 0.
