Operands:
S
1
: 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
. 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
7. 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 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.
