Post by pedrorgd on SFC Exit Action during SFCReset Flag ^{CODESYS Forge talk (Post)}
I have an SFC POU with an SFCReset Flag that I use to restart it from the beginning. It works properly. During an Action Step I set one variable to TRUE and I reset it to FALSE during the Exit Action. My question is if this Exit Action will be activated -and the variable reset to FALSE- if I get out of the active step using the SFCReset Flag.

Hi George, I do not know what the problem is with the syssocket implementation, but when i read the forums it seems the Net Base Services library is the recommended way to go. There is another more extensive example here: https://forge.codesys.com/prj/codesys-example/plc-chat-nbs/home/Home/ I have just tested this example and it works very well, also with closing and opening the connection from hercules... good luck!

Post by timo on Visualisierung: Tastatur vergrößern? ^{CODESYS Forge talk (Post)}
Hallo, Ich nutze den Stil White Style 3.5.16 mit ein paar farblichen Änderungen über den Stileditor. Was ich gerne machen würde, wäre die Tastaturen zu vergrößern, die sich auf dem Touchpanel öffnen wenn ein INT oder STRING eingegeben werden muss. Gibt es dafür "fertige" Variablen im Editor des Stils oder in Codesys selbst, mit dem die Größe hochskaliert werden kann? Oder muss ich jede Taste einzeln anpacken? Danke im Voraus :)

Post by reiterf on Visualisierungs-Stil White style, 3.5.16.0 verursacht Überseztungsfehler ^{CODESYS Forge talk (Post)}
Hi, ich möchte ein kleine Testaufbau visualisieren und hätte mich für den Stil "White" entschieden. Nun ist es allerdings so, daß dieser Stiel einige Fehler beim übersetzen erzeugt. Ich habe dann versicht auf den Basic-Style zurückzugehen -- dann sind auch die Fehler weg. Leider wird dann auf der WebVisu (nur am Gerät) kein Druckknopf mehr angezeigt. Ich habe die gleichen Fehler auf 2 Codesys-Installationen (Gleicher Software Stand, 2 PCs) Kann mir da jemand weiterhelfen?

Post by hismoon on Inheritence of struct, ^{CODESYS Forge talk (Post)}
Using a UNION instead of a STRUCT alone should give you that flexibility and only occupy memory once. And if you want to be really elegant, you could use an FB, which only holds PUBLIC VAR. Because a POU can use "EXTENDS"/inheritance. In CODESYS V3, an FB has a lot in common with C++ classes. Using ANY or ALIAS is rarely a good idea. It neither won't be pretty, nor have good readability and requires you to create a lot of error-prone things around it.

Post by imdatatas on Problem of assigning physical addresses to variables of type ARRAY OF ARRAY as MW and QW ^{CODESYS Forge talk (Post)}
Hello, I am encountering an interesting problem as below in SP20patch5 variable definition area. I think this is a bug. As can be seen in the attached screenshot, it assigns the same %MW or %QW address to all elements of the array. I hope Codesys team can solve this problem in the next version. Best regards, Imdat

Moin, kann es sein, dass dies auch schon wieder veraltet ist? Ich habe aktuell die 3.5 SP20 Patch 4 mit einem Paspberry 5 64bit SL am laufen und es wird leider nix geloggt. Muss man da etwas am Filter einstellen damit etwas geloggt wird? WÄre echt cool, wenn Codesys anfangen würde, Info´s in Form von Text einzupflegen....dann könnte man es auch nutzen. Brauche das Log bzgl. eines anderen Problems mit der "SysProcess.SysProcessExecuteCommand2", leider auch nicht gut kommentiert.

Bonjour DIEGORAMONM, très recemment,je pense avoir résolu un problème similaire en allant dans le Placeholder (Espace réservé) du Gestionnaire de bibliothèque. Dans cette nouvelle fenêtre, je sélectionne la bibliothèque qui pose problème, et dans la colonne du milieu je clic pour définir une bibliothèque de version inférieure. à la compilation, je suis passé de 484 erreurs à 0. :) J'espère que ce sera également le cas pour toi. Bon développement JM

Bonjour Diegoramonm, Je pense avoir eu un problème similaire. Je l'ai résolu en dégradant la version de la bibliothèque qui me posait problème après également une mise à jour. Ouvrir le gestionnaire de bibliothèque / Ouvrir l'onglet Espace réservé / La fenêtre Placeholders s'ouvre. Sélectionner la bibliothèque voulue puis double cliquer sur la bibliothèque(carré jaune)concernée et choisir une autre version. puis recompiler. Pour moi cela a marché du 1er coup : chance! Bon développment!

Depending on changes per cycle and the possibilitiy of your control unit to write remanent storage. Otherwise you need a buffering system to ensure save backup of last PI_Counter value.

Post by andrax on Stop Programm geladen Ausnahmefehler ^{CODESYS Forge talk (Post)}
Hallo, ich habe seid neustem ebenfalls dieses Problem auf den Raspberry. Codesys 3.5.18 Nach dem Download geht die SPS in STOP und es blinkt schwerer Ausnahmefehler. Der Fehler kommt sporadisch und ist nicht reproduzierbar. Es passiert beim kompletten Download, aber auch bei Änderungen. Wie kann ich den Fehler eingrenzen? Nachtrag: Wenn der Fehler kommt, ist die Runtime auf dem Raspberry nicht mehr ansprechbar. Der Raspberry selbst schon. Für einen neuen Download muss ich den Raspberry neu starten. Das selbe ist auch in der Programmierumgebung, die Software hängt sich auf.

Post by rpostwvu on Shared Memory Access Issues ^{CODESYS Forge talk (Post)}
I got the shared memory example. I'm pretty sure I'm successfully created a memory space, CreateResult returns 18. szName:='CodesysDataShare'; hShm := SysSharedMemoryCreate(szName, 0, ADR(uxiSize), ADR(CreateResult)); I'm trying to access this memory with a C# application, but I get "Unable to Find Specified File". I suspect that Codesys and/or Visual Studio code alters the name I choose? Being in Windows, I cant find a way to see the mapped memory list. ~~~ using (var mmfRead = MemoryMappedFile.OpenExisting("CodesysDataShare",MemoryMappedFileRights.ReadWrite)) ~~~

Hello, I need to execute "sudo" commands via CoDeSys 3.5 SP 19 P5 using the "SysProcessExecuteCommand2" function. Commands without sudo are no problem, but as soon as sudo is used in a .sh or a single command, it does not work. Command=AllowAll is entered under "SysProcess" in CODESYSControl.cfg. Nevertheless it does not work. Does anyone know what the problem could be? Greetings, Thomas

Hallo Herr Schwellinger, vielen Dank für die Antwort. Leider hat auch das weglassen des "sudo"-Befehls kein Erfolg. Folgendes passiert: Bild 1: Befehl in der Konsole eingegeben ohne sudo; Uhrzeit wird nicht gestellt (keine Berechtigung). Bild 2: Befehl mit sudo ausgeführt, Uhrzeit wird gestellt. Bild 3: Befehl ohne sudo von CoDeSys aus ausgeführt; Rückgabewert gibt die Uhrzeit an, die eingestellt werden sollte, Uhrzeit wird jedoch NICHT eingestellt. Haben Sie noch eine Idee was es sein könnte?

Hello everybody, I'm trying to understand the SL control extension package, more specifically, the external IODriver example, because C integration is very easy and I just made my first C component successfully. Ther External IODriver has no documentation and it's not clear how to proceed. Furthermore, there is no information on how to modify the device descriptor, which is necessary to import the device into the Codesys repository. Any advice ? Thank you in advance and best regards.
