Operation
When this block has a TRUE value in EN, it interprets the Value1 and Value2 values as BYTE and converts it into a WORD variable, 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
Example in Ladder
The examples above perform the conversion of two variable VALUE1 and VALUE2, in BYTE, 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 VALUE1 : SINT := 5; VALUE2 : SINT := 10; RESULT : WORD; END_VAR
RESULT := FB_BYTES_TO_WORD( EN:=DI1, Value1:=VALUE1, Value2:=VALUE2, ENO=>DO1);
