Operands:
S

: Source device 1 S
2
: Source device 2
Explanations:
1.
This instruction compares the content in S
1
and S
2
. 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.
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 (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.
