After reading with a BarcodeReader via Profibus this what i see is in HEX format (For example W#16#4C47) but whis what i chan is in ASCII format (4C=L, 47=G) , How I can convert HEX i to ASCII format.

The SCL code to do this would be:- [code] FUNCTION_BLOCK FB1001 VAR_INPUT W : WORD; END_VAR VAR_OUTPUT CH1 : CHAR; CH2 : CHAR; W : WORD; END_VAR CH1 := BYTE_TO_CHAR(WORD_TO_BYTE(W AND 16#00FF)); CH2 := BYTE_TO_CHAR(WORD_TO_BYTE(SHR(IN := (W AND 16#FF00), N := 8))); END_FUNCTION_BLOCK [/code] The STL code to do this would be (where w is a WORD and c1 and c2 are CHARS):- [code] L #w AW W#16#FF T #c1 L #w AW W#16#FF00 SRW 8 T #c2 [/code]
