Operands:
S

: Source device 1 S
2
: Source device 2
Explanations:
1.
This instruction compares the content in S
1
and S
2
. Take API240 (OR =) for example, if the
result is “=”, the continuity of the instruction is enabled. If the result is “
≠”, the continuity of the
instruction is disabled
2. OR※ (※: =, >, <, <>,
≤, ≥) instruction is used for parallel connection with contacts.
API No.

3.
When the MSB (16-bit instruction: b15, 32-bit instruction: b31) of S
1
and S
2
is 1, the
comparison value will be viewed as a negative value in comparison..
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 when the content in 32-bit register D100
(D101)
≥ K100,000.
