Operands:
S1: Source device 1 S2: Source device 2
Explanation:
1. This instruction conducts logic operation between the content in S1 and S2. 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.
2. OR# (#: &, |, ^) instruction is used for parallel connection with contacts.

221 OR& DOR& S1 & S2≠0 S1 & S2＝0
222 OR| DOR| S1 | S2≠0 S1 | S2＝0
223 OR^ DOR^ S1 ^ S2≠0 S1 ^ S2＝0
3. Operation:
& : Logic “AND” operation, | : Logic “OR” operation, ^ : Logic “XOR” operation
4. When 32-bit counters (C200 ~ C254) are used in this instruction, make sure to adopt 32-bit
instruction (DOR#). If 16-bit instruction (OR#) is adopted, a “program error” will occur and the
ERROR indicator on the MPU panel will flash
Program Example:
M60 will be ON either when both X2 and M30 are “ON”, or 1: the result of logical OR operation
between D10 and D20 ≠ 0, or 2: the result of logical XOR operation between CD100 and D200 ≠ 0.
OR D100 D200
OR D10 D20
