Part III FP Instructions
F216_DOR
32-bit data OR
Description
s1 s2 d
0 0 0
0 1 1
1 0 1
1 1 1
This instruction also exists as a P instruction (for FP2/2SH, FP3/5, FP10/10SH PLC types), which
is only executed at the rising edge of the EN trigger. Select [Insert P instruction] from the
"Instructions" pane if you require a P instruction. To facilitate reuse, the instruction then appears
under "Recently used" in the pop-up menu. Press <Ctrl>+<Shift>+<v> within the programming
area to open the list of recently used elements.

Variable Data type Function
s1 32-bit equivalent constant or 32-bit area
s2 32-bit equivalent constant or 32-bit area
d
ANY32
32-bit area for storing OR operation result
The variables s1, s2 and d have to be of the same data type.
For Relay T/C Register Constant
s1, s2 DWX DWY DWR DWL DSV DEV DDT DLD DFL dec. or hex.

No. IEC address Set If
R900B %MX0.900.11 for an instant the result calculated (output d) is 0.
In this example the input variables input_value_1 and input_value _2 are declared. However, you
The function performs a bit-wise OR operation on two 32-bit data items at inputs s1 and s2. The
result of the function is returned at output d.
