To convert a décimal digit to ASCII, you have to ADD 50 to your decimal digit.
For example : 5 (decimal digit) --> 5 + 50 = 55
55 is decimal ASCII code for decimal digit 5
To convert a hexadigit to ASCII, you have to ADD 16#30 to your decimal digit.
For example : 5 (decimal digit) --> 5 + 30 = 35
16#35 is hexa ASCII code for decimal digit 5
To convert a number you must isolate each digit includes the number, then add 50 or 16#30 to each isolate digit
For example to convert VAL1 to ASCII code :
VAR
Val1:UINT:=24;
VAL2, Dec_ASCII,Unit_ASCII : UINT;
END_VAR
(Program)
(Decade)
Val2:=Val1/10 (result =2, decade)
(ASCII code for decade)
Dec_ASCII:= Val1 + 50 = 52 (ASCII code for "2" )
(ASCII code for unit)
Unit_ASCII:= (Val1-(10 x Val2)) + 50 = 4 + 50 = 54 (ASCII code for "4", unit)
In this example, Val1 is only composed of 2 digits.
The program will be longer if val1 is more long !

Is there anyway to show the careracter of the ASCII code?
For example, I need to send "SMFHD4BCOCGKS1508" over CAN
So I have to convert the whole of it to DEC first, then send via CAN as BYTES.
At the other end I have to recieve the CAN BYTEs, convert to DEC, then back to the ASCII caraters.
Cheers,

To convert decimal to ASCII you can also use a pointer. I have not tried to use a pointer to convert ASCII to decimal but I would imagine it would be the same thing since you are just pointing to a memory location and pulling the data in the type that you need it.

Hi All,
I am quite new to CodeSys and have a queestion.
I need to convert a Decimal or Hex to ASCII.
Is there a simple way of doing it?

real_to_string
int_TO_STRING
ETC
OTHERWISE HAVE A LOOK AT THE OSCAT.LIB
at oscat.de
Thanks for that.
