Block that performs the conversion of a DWORD value into a LREAL value.

Ladder Representation

Block Structure

Variable Type	Name	Data Type	Description
VAR_INPUT	EN	BOOL	Block enabling
VAR_INPUT	Value	DWORD UDINT DINT	Value in DWORD
VAR_OUTPUT	ENO	BOOL	End of operation
VAR_OUTPUT	Result	LREAL	Value in LREAL

Operation

When this block has a TRUE value in EN, it interprets the Value value as DWORD and converts it into LREAL, storing in Result.

When EN has FALSE value, Result remains unchanged.

The ENO value forwards to the next Ladder block the EN value after the operation is completed.

Example in Ladder

dword_to_lreal_example01

The examples above converts variable VALUE, in BYTE, to a value in LREAL, writting the result in RESULT. The block successfully ends and the output ENO is enabled.

Example in ST

The example below displays the instructions for applying the example above in the ST language.

VAR

VALUE : DINT := 123954851;

RESULT : LREAL;

END_VAR

RESULT := FB_DWORD_TO_LREAL(VALUE);
