Post by jampid on Codesys Codebase Library Update ^{CODESYS Forge talk (Post)}
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!

Hi! I am using abb ac500 in automation builder v2.7 I have a problem with a new project. In the normal mode I have no problems, but in safety mode i cannot go online. I get 'Communication Error (#0) Logout Performed' message. I have tried changing the adress (level 1) in communication parameters. I tried 0.0.0.0.0 and 0.1.0.0.0 and 1.1.0.0.0 but it did no difference. What do you think could be causing this? Thanks!

Hello, I have an EtherNet IP adapter (GoPxL) running with a virtual PLC. I have successfully connected the adapter with green icons next to it. On WireShark I can see the data coming from GoPxL but on CODESYS it shows up as all 0. My firewall is turned off and I have enabled the device to always update variables. I tested my set up with Profinet and I can receive the data. Please let me know if you have any suggestions!

Hi geoweil, have you tried to save changed values to remanent area or using a VAR RETAIN? After restart you have to initialize Counter with last remanent value. 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. May you could read this Thread to get further help: https://forge.codesys.com/forge/talk/Engineering/thread/31e1c8349e/#bf48

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)) ~~~

Post by thomas-moba on "sudo"-Befehle über die Funktion "SysProcessExecuteCommand2" ^{CODESYS Forge talk (Post)}
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?

Post by john-martin on Control SL Extension Package doubts ^{CODESYS Forge talk (Post)}
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.

Hi, jain. wir haben mit IFM gesprochen. Sie sagen es liegt an Codesys selbst. Die Daten seien anscheinend nicht konsistent wenn das Projekt zu und erneut geöffnet wird, sei ein probkem von SP11.

Wir haben zwar einen Workaround rausgefunden aber jenachdem was du in der Safety treibst geht dieser dann nicht mehr. schreib mir zur not eine PN wenn du mehr wissen willst.

Post by alexgooi on Disable OPC-UA server ^{CODESYS Forge talk (Post)}
Dear Forum, I recently updated to the newest Codesys IDE (3.5 SP19 patch 5) The program wouldn't download cause of the amount of OPC-UA server tags (see picture) I'm not planning on using the OPC-UA server and therefore I unchecked the "Support OPC-UA features" checkbox in the symbol configuration. But this didn’t solve the issue of the OPC-UA server exceeding its license. How can I disable the OPC-UA server while still maintaining the symbol configuration. Thank you in advance Alex

Post by dominggus on Recipe Manager - RecipeManCommands, load & write wrong values, Bug? ^{CODESYS Forge talk (Post)}
I still have the same problem even when updating to CODESYS Recipes 4.3.0.0. My scenario: I'm trying to save/load an array of structs using the Visu: - Execute Command > "SaveRecipeAs" works properly - Execute Command > "LoadWriteRecipe" works not entirely: the structs of array[6] and array[7] should have been empty but were duplicates of array[4] and array[5]... the struct contains 26 variables and the array's length is 30.. Maybe there is a upper limit on recipe variable count?

Post by androidzz on Json Builder problem? ^{CODESYS Forge talk (Post)}
Dear reader, I am using the codesys JSON utilities SL, 1.9.0.0 library. And then specifically the FB JSONBuilder. I need to create a main object with at least 2 objects in it. The first object is no problem, but I cannot insert the second object into the main object. See attached my code and the result I get. I am assuming that I am doing something wrong with the parent index but have tried a lot and can't get it done. Kind regards, Rob

Post by stuartjr on Disabling forcing of specific variables ^{CODESYS Forge talk (Post)}
Is there a way that I can create a variable in a GVL that I can control with logic but a user can not put a force on this variable. I have looked at the access rights but this seems to only limit editing the GVL or POU. This variable will only be assigned a value in one POU but it will be used throughout many other POUs.

Post by wind-11 on Simulation Modubus ^{CODESYS Forge talk (Post)}
Hallo zusammen, ich bin über die Arbeit auf ein Problem in der Simulation gestoßen. In einem Test-Projekt haben wir eine Modbus Verbindung aufgebaut. Dies wollten wir mit Test-Werten simulieren. Verbindung hat auch funktioniert, jedoch sind leider die Werte eingfrohren und melden keine "laufenden Daten". (Bild im Anhang) Da es meine ersten Berührungspunkte mit Codesys sind und mein Kollege an anderer Stelle weiter arbeitet, hatte ich gehofft, dass vielleicht hier jemand eine Idee hat. MfG und schon jetzt ein Danke vorweg.

Hello everyone, I encountered a problem in the simulation while working. In a test project we set up a Modbus connection. We wanted to simulate this with test values. The connection also worked, but unfortunately the values are frozen and do not report any “current data”. (Picture attached) Since these are my first points of contact with Codesys and my colleague continues to work elsewhere, I was hoping that someone here might have an idea. Kind regards and thanks in advance.

Post by timo on Backup / Restore über HMI? ^{CODESYS Forge talk (Post)}
Hallo, Über die Benutzeroberfläche von Codesys 3.5 kann ich unter Backup/Restore eine tbf-Datei erzeugen und laden. Ich suche nach Möglichkeiten beide Schritte über meine HMI durchzuführen, um z.B. ein Backup über die HMI auf der SPS oder einer SD Karte zu speichern und ebenfalls über die HMI ein Backup von dort oder von einer SD Karte zu laden. Ich habe bisher leider gar nichts im Netz dazu gefunden. Hat da jemand einen Tipp für eine Bibliothek oder ist das eher herstellerspezifisch gelöst, dass ich dort nachhaken sollte? Danke im Voraus.

Post by carohe on VisuNamespace != null ^{CODESYS Forge talk (Post)}
Hello, this error occured frequently over the past couple of weeks. I found out, when adding a webvisu, CODESYS added Visu libraries in the library manager. One of the libraries was the "VisuElemsAlarm" library. In my case it added this one with the version 4.3.0.0. However another library that also contained the "VisuElemsAlarm", used the "VisuElemsAlarm" with the version "4.4.0.0". After changing the Version "4.4.0.0" and uninstalling this version, the error has not occured anymore. Regards, carohe
