TO_UDINT

Overloaded conversion to unsigned DOUBLE INTEGER

This instruction converts a value of any allowed data type into a value of the data type UDINT.

Parameters

Input

Unnamed input (INT, UINT, DINT, UDINT, REAL, LREAL, BOOL, WORD, DWORD): Value to be converted

Output

Unnamed output (UDINT): 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
		udiValue: UDINT:=0;
		uiValue: UINT:=0;
		bStart: BOOL:=FALSE;
	END_VAR

POU body

When the variable bStart is set to TRUE, the function is carried out.
