Operands:

: Data source device 1 S
2
: Data source device 2
Explanations:
1. See the specifications of each model for the range of operands.
2. 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.
3. AND
※ (※: =, >, <, <>, ≤, ≥) is a comparison instruction is used on series contacts.

4. When 32-bit counters (C200 ~ C255) are used in this instruction for comparison, make sure to adopt 32-bit
instruction (DAND
※). If 16-bit instructions (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, Y10 = On.
2. When X1 = Off and the content in D0 ≠ K-10, Y11= On will be retained.
3. When X2 = On and the content in 32-bit register D0 (D11) < 678,493 or M3 = On, M50 = On.
