Operands:

: Source device 1 S

: Source device 2

Explanations:

1. This instruction compares the content in S

and S

. Take API232 (AND =) 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. AND※ (※: =, >, <, <>, ≤, ≥) instruction is used for serial connection with contacts.

3. When the MSB (16-bit instruction: b15, 32-bit instruction: b31) of S

and S

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 (DAND※). If 16-bit instruction (AND※) is adopted, a “program error” will occur and

the ERROR indicator on the MPU panel will flash.

Program Example:

1. When X0 = ON, and the content in C10 = K200, Y20 = ON

2. When X1 = OFF and the content in D0 ≠ K-10, Y21= ON and latched.
