Operands:
S

S
2 : Data source device 2
Explanations:
1. This instruction compares the content in S
1
and S
2
. If the result is not “equal”, the continuity of
the instruction is enabled. If the result is “equal”, the continuity of the instruction is disabled.
2. OR※ (=, >, <, <>, ≦, ≧) instruction is used for direct connection with BUS.

3. If the most left bit of S
1
and S
2
(16-bit instruction: b15、32-bit instruction: b31) is “1”, the compare
value will be regarded as the negative value for comparison.
4. When 32-bit counters (C200 ~) 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 panel will flash and the connecting controller can not run..
Program Example:
1. When X1 = On, or the value of C0 is equal to the value of K200, Y10 = On.
2. When X2 and M30 are both, or the value of 32-bit data (D101, D100) is equal to or higher than
K100,000, M60 = On.
