Block Structure

Variable Type	Name	Data Type	Description
VAR_INPUT	EN	BOOL	Block enabling
VAR_INPUT	Value	LREAL	Value in LREAL
VAR_OUTPUT	ENO	BOOL	End of operation
VAR_OUTPUT	Result	WORD UINT INT	Value in WORD

Operation

When this block has a TRUE value in EN, it interprets the Value value as LREAL and converts it into WORD, 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

lreal_to_word_example01

The examples above converts variable VALUE, in LREAL, to a value in WORD, 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 : LREAL := 330.6;

RESULT : INT;

END_VAR

RESULT := FB_LREAL_TO_WORD(VALUE);
