
The instructions are used to compare the value in S
1
with that in S
2
.
Take the instruction AND= for instance. If the comparison result is that
the value in
S
1
is equal to that in S
2
, the condition of the instruction is
met. If the comparison result is that the value in S
1
is not equal to that in
S
2
, the condition of the instruction is not met.


If a 32-bit counter is used, the 32-bit insturciton 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 X0.1 is OFF and the value in D0 is not equal to K-10, Y1.1 is set
to ON.

When X0.0 is ON and the present value in C10 is equal to K200, Y1.0 is
ON.

When X0.2 is ON and the value in (D11, D10) is less than 678,493, or
when M3 is ON, M50 is ON.
