SCL Siemens array question

vib · May 1, 2022

Hello,
When you want compare values of an array to a range of numbers is it a right way to do that?

Code:

FUNCTION ADD
  VAR_IN_OUT
     A:ARRAY[1..50] OF INT;
  END_VAR
  VAR_TEMP
    I:INT;
  END_VAR
  BEGIN
    I:=0;
  WHILE I<50  DO
    IF(A[I]:=1, 3, 7, 9, 12, 15, 20, 21, 14, 17, 30, 33, 36, 39, 42, 49 )THEN
       A[I]:=A[I]+12.5;
    END_IF
   I:=I+1
   END_WHILE
   ADD:=A[I];
END_FUNCTION

Or I have to check 1 per 1 value? I wanna know if you can check it like that

Oh dear .... anyway..

I dont have my programming pc at hand, but I think you can do it like this:

Code:

FOR i:=1 TO 50 
  CASE A[i] OF
    1,3,7,9,12,14,15,17,20,21,33,36,39,42,49: // match found
  ELSE
    // match not found 
  END_CASE ;
END_FOR ;

Why are you adding 12.5 to an integer in your example code?

Oh can you use CASE like that? using ELSE inside?

Sure, you can omit the ELSE part, but using it results in cleaner (more readable) code.

To make sure that you understood, it works so, that if any of the cases was not there then the else part is executed.
