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
. If the result is not “0”, the
continuity of the instruction is enabled. If the result is “0”, the continuity of the
instruction is disabled.
3. AND# (#: &, |, ^) is an operation instruction used on series contacts.
API No.

4. &: Logical “AND” operation
5. |: Logical “OR” operation
6. ^: Logical “XOR” operation
Example
1. When X0 = On and the result of logical AND operation of C0 and C10 ≠ 0, Y10 =
On.
2. When X1 = Off and the result of logical OR operation of D10 and D0 ≠ 0 and X1 =
On, Y11 = On will be retained.
3. When X2 = On and the result of logical XOR operation of 32-bit register D200
(D201) and 32-bit register D100 (D101) ≠ 0 or M3 = On, M50 = On.
