Part III FP Instructions
F238_DGBIN
32-bit Gray code -> 32-bit binary data
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
s source area for gray code
d
ANY32
destination area for storing converted data
For Relay T/C Register Constant
s DWX DWY DWR DWL DSV DEV DDT DLD DFL dec. or hex.
d - DWY DWR DWL DSV DEV DDT DLD DFL -
In this example, the input variable input_value is declared. However, you can write a constant
directly at the input contact of the function instead.
Description
The function converts a gray-code value at input s to binary data. The result of the conversion is
returned at output d.

Example
In this example, the same POU header is used for all programming languages. For an example
using IL (instruction list), please refer to the online help.
POU header
All input and output variables used for programming this function have been declared in the POU
header.
Body
When the variable start is set to TRUE, the function is carried out.
