Post by swe-hob on call of a method of a function block in another program

Hi, Let's assume following: PRG_1 fb_1 : fbExample1; fb_1.method_1 do something... PRG_2 fb_2 : fbExample2; fb_2.method_2 if xTest then PRG_1.fb_1.method_1(); end_if; Is there a reason why runtime hangs when I call the method_1 in PRG_1 from a method in PRG_2? Both programs run in the same task. No chance that any other program calls the method. What I practically do there is that in the program PRG_2 I add a structed object into a buffer. In PRG_1 I just process the items in the buffer.

Das CODESYS SVN AddOn hat Minimal-Versions-Vorgaben. In SP9 funktioniert wohl die neueste SVN Version nicht. Da mal am besten im Store auf die Release Notes auf der Download-Seite schauen. Da steht meistens, ab wann Minimal-Versionen erhöht wurden. (Required CODESYS version) V4.2.6.0 vom SVN AddOn scheint die letzte zu sein, die mit SP9 offiziell funktioniert. Eigentlich sollte das der CODESYS Installer / Package Manager abfangen, aber hmm.

Hi, I am trying to access active alarms in code(As alarm count variable updates only when we go to to alarm table frame in visualization). I wrote following code but it is not working: VAR iCountActiveAlarms : INT; parritfActiveAlarms : POINTER TO ARRAY[0..0] OF IAlarm; itfAlarmManagerClientAll : IAlarmManagerClient; END_VAR AlarmManager.g_AlarmHandler.GetActiveAlarms( itfAlarmManagerClient :=itfAlarmManagerClientAll, iCountActiveAlarms => iCountActiveAlarms, parritfActiveAlarms => parritfActiveAlarms); The Value is always 0. Please help.

Thank you very much for your reply. That helped, it is editable if the library is at root level. Unfortunately, I noticed that I am not using the MQTT client SL, but the AzureMQTTClient from the Azure IoT Hub Client SL library. At first glance, there is no parameter to increase the message size. Does anyone know how to increase this in the library or is it simply not possible here?

Hi, I clone a git repository with VersionUpdateFlags.SilentMode, works fine But now I want to checkout a specific commit (with branch_copy command). When using the branch_copy command there is no VersionUpdateFlags and I get this annoying "Project Environment" prompt, blocking further execution of my script without user input. I already tried something like system.prompt_answers[???] = PromptResult.Cancel but I don´t know the string I need here.. The goal is to have a script that clones a repository and compiles every tag + create compiled libraries.

However, I cannot connect and it restarts. the window to rewrite my identifiers. However it is the correct identifier and password I do not understand why. When I try to put false identifiers there strangely it tells me that these are not valid identifiers. There is something what can I do? Sincerely

Das Codesys-Objekt 'Einheiten umrechnen' wirkt auf timeVar (TIME) z.B. innerhalb eines Visu-Rechtecks und funktionier in den Grundfunktionen einwadfrei. Die Ausgabe der Std. von timeVar läuft. Beispiel: Bei t#3d2h10m wird wunschgemäß 74h (volle Std-Anzahl). Die Grenzüberwachung Max= 10 funktioniert nicht, da die Angabe scheinbar ms erwartet (arbeitet mit 10ms). Irgend wie muss man jetzt codesys davon überzeugen, dass auch für Min und Max die Einheitenumrechnerei wirken soll, wobei die Eingabe der Grenzen in Std erfolen muß. Hat jemad einen TiPPPPPPPPP?

i know, this is the reason for us either. PLC-Handler is to big, and only available with additional Contracts/Costs. OPC-UA is to slow for us. As described, there is a solution available, but im not allowed to post them here. i would prefer you send a message at codesys store by "have a question" or similar called. Not sure. Or, if an Codesys-Official Member allows to share that informations, i can give you the right hints.

also, wenn du noch lscpu output posten konntest, wäre das super genauso angaben über die im detail verwende pi-hw-version. das logfile sagt keine nennenswerten fehler. der logger ist wohl aber auch nicht voll aufgedreht. auch könntest du codesys via console starten im debug-mode hoerzu ins opt/codesys/bin berzeichniss wechseln und dann ./codesyscontrol -d dann spuckt codesys (weil ohne configfile gestartet, alle ausgaben in der shell. spätesrens hier sollte die ursache zu sehen sein. die 30 sekunden ohne logfile deuten darauf hin, das die runtime meint nicht auf der zielplattform installiert zu sein

Hallo, du solltest dir angewöhnen Präfixe für die Datentypen zu nutzen. Dann ist das auch lesbarer. Aus value wird rValue für ein REAL oder wValue für ein WORD. Daher ist jetzt nicht ersichtlich mit welchen Datentypen du dort arbeitest und was die Bausteine an den EIN- und Ausgängen erwarten. Du kannst aber explizit eine Typkonvertierung durchführen indem du am Ausgang noch einen Baustein "TO_WORD" setzt.

Hallo pmolke vielen Dank für Deinen Hinweis. Natürlich kann man alles nachbauen, das hat Vor- aber u.U. auch Nachteile. Ich würde mir aber gerne die Macros ansehen. Hast Du einen Link? Wir wollen eine Standardlösung einsetzen, sofern sie dann funktioniert, und sind da auf dieses CodesysObjekt gestoßen. Bisher haben wir da unsere Zweifel an der Implementierung oder der Dokumentation, so werden Bereichstypen bei ganzen Zahlen scheinbar auch nicht korrekt verarbeitet.

If anyone still has the ecoPlus21 installer or knows where it can be downloaded, please let me know. It’s needed only for recovery and migration of an existing project. Thanks in advance,

Hi I recently started learning Codesys SoftMotion. At first, I mainly used YouTube videos. I stopped at two videos where the same problem keeps recurring. fbReadPos( Axis := X_Axis, Enable := TRUE, Position => gAxes.lrActualPos); <- axis cannot move I checked the entire code line by line. Zero errors. GPT spits out nonsense, throwing up increasingly worse errors. And when I copy its code, it says the code is wrong and gets stuck in a loop of its own stupidity. Can anyone explain why it doesn't work? Link to the video below: https://www.youtube.com/watch?v=CYa2HvYZgbM&list=PLsEhEcYjG7na0OveU7cqFXBx7ATyGGn0A&index=3

From what I can find online it's got to do with electronic records and validation. Has anyone developed any software using this or are there codesys librarys that can make my life easier in writing this code

Ich habe eine Wallbox, die ich gerne per Modbus ansteuern würde. Die Normale Modbus-Kommunikation, um ein paar Werte auszulesen klappt auch. Wenn ich aber Zugriff auf bestimmte Modbus-Register haben möchte, benötigt die Wallbox ein TLS-Zertifikat. Das Zertifikat habe ich bereits erstellt und im Security-Sreen unter Eigene Zertifikate hochgeladen. Weiter komme ich aber nicht mehr. Wie baue ich eine TLS-Verbindung mit der Waalbox auf? Vielleicht hat das ja schonmal jemand gemacht und ein Beispiel für mich. Ich bin über jede Hilfe sehr Dankbar!

You can definitely pull the actual system time into CODESYS without too much trouble. Take a look at the SysTimeRtc or SysTime library—both let you read the current date and time from the Raspberry Pi. You can call SysTimeRtcGet() or SysTimeGetTime() in your PLC code and then format the hours, minutes, and seconds into variables that feed your 7-segment visualization. Once you’ve mapped those values, your Visu display will update automatically each cycle. It’s a pretty common approach for clocks in CODESYS, so you should be able to get it working quickly. golf hit

Let's say I have a CODESYS controller (PLC) with a runtime version around 3.5.19. If I use development software version 3.5.21.40 or a later version that will be released in the future for programming, could there be any problems or malfunctions in the controller's program execution or in the execution of the new, updated function blocks from the newer software? I mostly work with servo-based motion applications, so please keep that in mind when answering, and provide a detailed answer so I don't have to email you again about this topic.

Create an array of STRING and 1 INT variable, e.g.: asMyString : ARRAY[0..9] OF STRING; iIndex : INT; Then place a "Table" object in the visualization: - link this to the string array variable. - Check the option "Use Template" - Then in the Input Configuration - add the "Write Variable" command Somewhere else add a "Combobox, array" - link this to the same array. - And link the index to the INT variable. In the Combobox, you can then select one of the strings from the array. The index variable will indicate which selection has been made.

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND or OR.
