Good morning, I'm new on Codesys Forge, so I'm not sure if this is the right place to talk about my problem. When I open my WebVisu pages with Microsoft Edge, or Chrome, the background and also some rectangles blinking without reason!!! The application is developed with Codesys 3.5.17.10 and run on Codesys HMI, same version (3.5.17.10). After several experiments I discover that the problem happens when I made dynamic the "End of area" property of a meter object, but I can't understand why this blinking...

Aufgrund einer Schnittstellenänderung muss ich meine Messagebuffer erheblich vergrößern. U.g. Konstante bestimmt die Größe einer Byte-Array-Definition, die in einer Struktur für 9 Botschaften verwendet wird. Ich benötige also 177372byte zusätzlichen Speicher in dem Modul in dem die Struktur als lokale Variable angelegt wird. Dynamisches Allokieren zur Laufzeit möchte ich vermeiden, damit ich nicht während des Betriebes Fehler aus dem Allokieren behandeln muss. Für ein Reservieren des Speicherbereiches...

I am adding elements of an ARRAY using pointer to access each element inside a FOR loop and the FOR loop does not stop! What is the right way to use pointers in such case?? I have another loop that is not using pointer and it stops but the loop using pointer keep on adding. METHOD FB_Init: BOOL VAR_INPUT bInitRetains: BOOL; // TRUE: the retain variables are initialized (reset warm / reset cold) bInCopyCode: BOOL; // TRUE: the instance will be copied to the copy code afterward (online change) END_VAR...

Leider habe ich keine Lösung für das Problem gefunden. Glücklicherweise konnte ich die "CODESYS Control for Raspberry Pi MC SL" wieder auf dem 32bit OS zum Laufen bringen.

with every call of the FB500 it keeps adding the INTs of the array to the sum variable. set sum to 0 before you start the loop.
