You can try this setup: DINTVar := SHL(INT_TO_DINT (Low_Word_INT_Var),16) + INT_TO_DINT(High_Word_INT_Var);
Why will it retain the sum value from the last call? This is how PLC work. Usually variables only get initialized after a download or a reset (i.e. power loss). RETAIN variables are saved in a special kind of RAM and keep their value after a power loss. To initialize variables on every call of your FB use the VAR TEMP block. VAR_TEMP sum : INT; END_VAR
I need to connect 2 computers on the same network that are running codesys, so that they can receive and change variable values from each other. This connection must preferably be made using Modbus.

Hello everyone, I have a working SPI connection (with transferExt) between a Raspberry master with Codesys and an ESP32 slave. I would also like to use a few GPIO pins. Is there a problem with using SPI AND GPIOs? Environment: Raspberry Pi 4+ with Raspian from Oct 23 Codesys V3.4 SP19 Patch 5 with Runtime Version 4.10.0.0 Device: GPIOs B+/Pi2 My problem: The status is displayed as “GPIOs : not running”. And also during mapping the message “The bus is not running. The values shown are perhaps not...
Ok yes now the loop has stopped when I set sum to zero before the for loop. Why will it retain the sum value from the last call?

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...
