Explanation
1. S
1
: Data source device 1 S
2
: Data source device 2
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
API No.

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.
