Explanations:
1. DVP-ES2/EX2 series PLCs whose version is 3.20/DVP-SS2 series PLCs whose version is
3.00/DVP-SA2 series PLCs whose version is 2.60/DVP-SE series PLCs whose version is
1.20/DVP-SX2 series PLCs whose version is 2.40 (or above) are supported.
The absolute value of the difference between S
1
and S
2
is compared with the absolute value of S
3
.
Take LDZ= for example. If the comparison result is that the absolute value of the difference
between S
1
and S
2
is equal to the absolute value of S
3
, the condition of the instruction is met. If
the comparison result is that the absolute value of the difference between S
1
and S
2
is not equal
to the absolute value of S
3
, the condition of the instruction is not met.
The instruction can be connected to a busbar.

If the values of the most significant bits in S
1
, S
2
, and S
3
are 1, the values in S
1
, S
2
, and S
3
are
negative values.
A 32-bit counter (C200~) must be used with the 32-bit instruction DLDZ※. If it is used with the 16-bit
instruction LDZ※, a program error will occur, and the ERROR LED indicator on the PLC will
blink.
