
The instruction is used to compare the value in S
1
with that in S
2
. If the
comparison result is not 0, the condition of the instruction is met. If the
comparison result is 0, the condition of the instruction is not met.


If a 32-bit counter is used, the 32-bit instruction DAND# must be used. If
a 32-bit counter and the 16-bit instruction AND# are used, a program
error will occur, and the ERROR LED indicator on the motion control
module will blink. (C200~C255 are 32-bit counters.)


When X0.0 is ON, a logical AND operator takes the values in C0 and
C10, and performs the logical AND operation on each pair of
corresponding bits. If the operation result is not 0, Y1.0 will be set to ON.

When X0.1 is OFF, a logical OR operator takes the values in D10 and
D0, and performs the logical OR operation on each pair of
corresponding bits. If the operation result is not 0, Y1.1 will be ON.

When X0.2 is ON, a logical XOR operator takes the values in (D201,
D200) and (D101, D100), and performs the logical exclusive OR
operation on each pair of corresponding bits. If the operation result is
not 0, or if X0.3 is ON, M50 will be ON.
