Operands:

: Data source device 1
S
2
: Data source device 2
Explanations:
1. See the specifications of DVP-PM for its range of use.
2. #: &, |, ^
3. LD# instruction compares the content in
S
1
and
S
2
. If the result is not “0”, the instruction will be ON. If the result
is “0”, instruction will be OFF.
4. LD# can be connected directly with bus.

5. &: Logical ‘AND’ operation
6. |: Logical ‘OR’ operatioin
7. ^: Logical ‘XOR’ operation
8. When 32-bit counters (C200 ~ C255) are used in this instruction for operation, please adopt 32-bit instruction
(DLD#). If 16-bit instruction (LD#) is adopted, “program error” will occur, and the ERROR LED indicator on the
panel of DVP-PM will flash.
Program Example:
1. When the result of logical AND operation of C0 and C10 ≠ 0, Y10 will be ON.
2. When the result of logical OR operation of D200 and D300 ≠ 0 and X1 = ON, Y11 will be ON and held.
3. When the result of logical XOR operation of C201 and C200 ≠ 0 or M2 = ON, M50 will be ON.
