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

Ladder Representation

Block Structure

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

Operation

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

Block Flowchart

WORD_TO_DWORD_flowchart

Example in Ladder

WORD_TO_DWORD_example01

WORD_TO_DWORD_example02

The examples above convert the VALUE variable, in WORD, into a DWORD value storing the final result in RESULT. The block ends with success and ENO output is activated.

Example in ST

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

VAR

VALUE : INT := 562;

RESULT : DINT;

END_VAR

RESULT := FB_WORD_TO_DWORD(EN:=DI1, Value:=VALUE, ENO=>DO1);
