WOR, WORP: 7 steps
DWOR, DWORP: 9 steps
Operands:
S
1
: Source data device 1
S
2
: Source data device 2
D
: Operation result
Explanations:
1. WOR instruction conducts logical OR operation of
S
1
and
S
2
and stores the result in
D
2. When WOR is used as 16-bit instruction, Z device cannot be adopted; when WOR is used as 32-bit instruction,
V device cannot be adopted.
Program Example 1:
When X0 = ON, the 16-bit data source D0 and D2 are analyzed and the result of the logical OR is stored in D4.

Program Example 2:
When X1 is ON, the 32-bit data source (D11, D10) and (D21, D20) are analyzed and the operation result of the
logical OR is stored in (D41, D40).
