Explanation
The instructions are use
d 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 DVP-20PM series motion
controller used will blink. (C200~C255 are 32-bit counters.)
Example
When X1 is OFF and the value in D0 is not equ
al to K-10, Y11 is set to ON.
When X0 is ON and the present value in C10 is equal to K200, Y10 is ON.
When X2 is ON and the value in (D11, D10) is less than 678,493, or when M3
is ON, M50 is ON.
