DWORD_BCD_TO_DINT

Binary value of DWORD into DOUBLE INTEGER

DWORD_BCD_TO_DINT converts a binary coded value of the data type DWORD into a binary value of the data type DINT in order to be able to process a BCD value in double word format.

Parameters

Input

Unnamed input (DWORD_BCD): Input data type

Output

Unnamed output (DINT): Conversion result

Example

POU header

All input and output variables used for programming this function have been declared in the POU header. The same POU header is used for all programming languages.

	VAR
		DINT_value: DINT:=0;
		BCD_value_32bit: DWORD:=0;
	END_VAR

This example uses variables. You can also use a constant for the input variable.

BCD constants can be indicated in Control FPWIN Pro as follows:

2#00011001100101010001100110010101 or 16#19951995

POU body

BCD_value_32bit of the data type DOUBLE WORD is converted into a DOUBLE INTEGER value. The converted value is written into DINT_value.
