How do i set an array of DINT IN S7 SCL? (SCL V5.3 SP1)
For a REAL's and INT's it works just fine:

Reals : ARRAY[1..10] OF DINT := 0,0,0,0,0,0,0,0,0,0;
Integer : ARRAY[0..10] OF INT := 0,0,0,0,0,0,0,0,0,0;

How to do this for DINT's?
everything i try gives a compilation error in SCL.



Thx in advance.

The line you show prefixed by "Reals :" does seem to define an ARRAY of DINT correctly. What you have created is an ARRAY named "Reals" which contains DINTs! The default value for numeric data-types in an ARRAY is 0 or 0.0 so you don't actually need the assignment here.

I think there also some way of assigning an identical value to every element in ARRAY, like

Reals : ARRAY[1..10] OF DINT := 0;
DINTs : ARRAY[1..10] of DINT := 0;

should produce two identical ARRAYs with different names.

What name are you using when you try to creat an ARRAY of DINT? Could it be a reserved word like 'DINT' rather than DINTs?

The following code compiles ok:

Code: 
FUNCTION_BLOCK FB10
VAR_TEMP
  // Temporary Variables
END_VAR
VAR
  // Static Variables
iArrayOfInts: ARRAY[0..10] OF INT := 0,0,0,0,0,0,0,0,0,0;
rArrayOfReals: ARRAY[0..10] OF REAL := 0,0,0,0,0,0,0,0,0,0;
iArrayOfDInts: ARRAY[0..10] OF DINT := 0,0,0,0,0,0,0,0,0,0;
END_VAR
  // Instruction Section
  ;
END_FUNCTION_BLOCK

Hello Ken
Sorry i typed an error i ment:

REALs : ARRAY[1..10] OF REAL := 0,0;
DINTs : ARRAY[1..10] of DINT := 0;

The name DINT or DINTs is not used twice.



hello L D[AR2,P#0.0]
I tried to comile it in a new SCL file and it worked just fine,
In the old file the lines were whitin an STRUCT area, maybe that is not allowed.

But anyhow, my problem is solved, Thanks guys.
