    Hi Guys
    i am trying to define a Constant array in Var Constant....

    i initialise it like this:

    intEntranceControl : ARRAY [0..5, 0..1] OF DINT     := [-1000,  20, 1400,   70100,  71427,  72532   ,
                                                            80,     100,1200,   1200,   100,    80      ] ;

    but then i get weird values, some missing, some twice and the order seems completely wrong... can you please point me in the right direction?
    Thank you

    Seems specific to your setup.
    on CODESYS Control Win V3 x64 3.5.17.20 I get the expected results (see attached).
    What are you running it on?
    Also a possibilty, is nd having an array out of bounds problem, writing to memory it shouldn't.

    hmm, kinda weird... unfortunately not the first time i got weird behaviour on codesys for raspberry pi....

    i'll do a test with a empty project to make sure i have no other issues that can interference...

    hmm, the problem seems to sit a little deeper, i just tested on Raspberry pi 4.2.0.0, in SP16.60 and SP17 in a empty project... works fine on both.

    there must be a issue with my current project.
    this is how i initialize all constants. do you see a error here?

    VAR CONSTANT
    dintPositionTolerance : DINT := 10;
    dintControlTolerance : DINT:=800;
    intSpeedLimit : INT :=1100; 
    intSpeedLimitEntrance : INT := 320;
    intFix : UDINT :=   10023072;
    intBottomStationPos : UDINT :=  1255875;  //position of the Bottomstation for reset Position manual pos in cm  +10000 /0,008 
    intTopStationPos    : UDINT := 10185625;  //position of the Topstation for reset Position manual     pos in cm +10000 /0,008   

    intEntranceControl : ARRAY [0..5, 0..1] OF DINT     := [-1000,  20, 1400,   70100,  71427,  72532   ,
                                                            80,     100,1200,   1200,   100,    80      ] ;
END_VAR

    btw. if i init like this:

        intEntranceControlP : ARRAY [0..5] OF DINT  :=  [-1000, 20, 1400,   70100,  71427,  72532   ];                                      
    intEntranceControlS : ARRAY [0..5] OF DINT  :=  [80,    100,1200,   1200,   100,    80      ] ;

    that works...

    Can you post a project which reproduces it?
    Your latest declaration works fine on my Pi. (screnshot)
