Block that performs the conversion of a BCD code into a WORD 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 BCD
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 BCD and converts it to 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

BCD_TO_WORD_example01

BCD_TO_WORD_example02

The above example converts the VALUE variable, in BCD, into a WORD 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 : WORD := 51;

RESULT : WORD;

END_VAR

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