Hi,

Below is the function am using but i did not understand how the conversion works here.

function IDVAR:string
var_input
ID_VARONE:string;
ID_VARTWO:STRING;
end_var
VAR
TEMP:STRING;
END_VAR

TEMP:=CONCAT(ID_VARONE,'^');
TEMP:=CONCAT(TEMP,ID_VARTWO);
IDVAR:=(TEMP,'^');

function TEST:string
var_input
VarSARID:string;
Act_Count:udint;
end_var

TEST:=IDVAR('12345',UDINT_TO_STRING(Act_Count));

In codesys i did not find the UDINT_TO_STRING conversion but it is working any thing is hidden?

Thanks
sarath

Nothing hidden.
i like to propose you the use of the F2 key.
there you will find every conversion and any thing you can type in at a particular moment.

Thanks for the info i did not find it in the help file,I thought all conversions can be found in help file

IDVAR:=(TEMP,'^');

this is not allowed
it should read IDVAR:=TEMP;
however you can do this in previous line

Hi,

I misstyped it should be

IDVAR:=CONCAT(TEMP,'^');

Thanks
