Ok, nice solution.

I found the solution to the problem, with the method of the strings %s
I also managed to improve because I have also introduced the minutes

// Global Variable
   gvl.Tempo_A: DWORD; //  TIME();
   gvl.testStringa : STRING;
   gvl.testBoleana : BOOL;
//Function Block
VAR
   min: STRING;
   sec: STRING;
   cent: STRING;
   mill: STRING;
   x: DWORD;
   a: DWORD;   
   b: DWORD;
   c: DWORD;
END_VAR
min := DWORD_TO_STRING(gvl.Tempo_A/60000);
x := (gvl.Tempo_A / 1000) MOD 60;
b := x MOD 10;
a := (x - b) / 10;
sec := Concat(DWORD_TO_STRING(a), DWORD_TO_STRING(b));
x := (gvl.Tempo_A MOD 1000) / 10;
b := (gvl.Tempo_A / 10) MOD 10;
a := (x - b) / 10; 
cent := Concat(DWORD_TO_STRING(a),DWORD_TO_STRING(b));
x := gvl.Tempo_A MOD 1000;
c := x MOD 10;
b := (gvl.Tempo_A / 10) MOD 10;
a := (x - b) / 100; 
mill := Concat(DWORD_TO_STRING(a), Concat(DWORD_TO_STRING(b), DWORD_TO_STRING(c))); 
IF gvl.testBoleana THEN
gvl.testStringa := Concat(Concat(Concat(Concat(min, ':'),sec), '.'), mill);
ELSE
gvl.testStringa := Concat(Concat(Concat(Concat(min, ':'),sec), '.'), cent);
END_IF

I think this is the only solution if there is another way someone enlighten me

Thanks ... and good job

You can set the text as %.2f
The problem is, as far as I know, you cannot modify the number of decimal at runtime

Zitat:
Ah ok, like in WinCC Flexible.

Yes or Movicon

ok with expression is cool ... but if you set the text to %f in run i see 6 decimal point

A workaround could be to set the 'Text variable' as expression. See the attachment

is the integer variable to display, is the scale factor. In your situation should be 10,100,1000 etc.

thanks for the reply
Too bad you can not do
Perhaps the best way is to use the string?
By formatting the string in the code and then displays it in a rectangle?

Zitat:
Anyway, why do you want to show an integer as #.00 if it cannot uses decimal values? This could confuse the user

I think it is not possible to change %.2f into %.3f because this is a design time parameter.

Integer variables don't have a decimal portion, the '.#' string is ignored. If you want you can create a floating point variable to show. In your routine convert the integer into a float.

perhaps I expressed myself badly, I try to explain it again:

In one visualization screen i have one rectangle for display one variable value.
wehn i develop, if i put the text name %.2f , in run mode i see the value with two decimal point.
The question is: i want switch from code %.2f or %.3f ... is possible? if yes how?
Second question, this format is possible only for floating point variable or is possible also for integer variable (eg. %.2d)?

Thanks in advance

Hello everyone, I need to change from the PLC code the Text property of a rectangle.
To display two decimal i use the following string "% .2f", but I predict that it will also change to three decimal "% .3f".
Please someone can post a code sample that uses the Visu library?

Thank You.
