Operands:

Explanations:

1. See the specifications of each model for the range of operands.

2. This instruction compares the content in S

and S

. 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.

3. OR

※ (※: =, >, <, <>, ≤, ≥) is an comparison instruction used on parallel contacts.

4. 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 present value of C10 = K200, Y0 = On.

2. M60 will be On when X2 = On, M30 = On and the content in 32-bit register D100 (D101) ≥ K100,000.
