Post by yannickasselin on How to sort JSON object in codesys ^{CODESYS Forge talk (Post)}
Just adding: sSubscriberdata := ''; Right before your memcopy should fix the extra characters. It is because your are copying 36 characters into a string which can contain more than 36 characters and there is garbage left in the extra characters. Regarding the parsing of json, I usually build a structure that mirrors the json data and use the available methods in the IIoT library to parse the data and fill the structure.

Post by corriibme on Setting array values with JSON Utilities SL ^{CODESYS Forge talk (Post)}
I have been trying to set an array value to a JSON structure of this form: {"key": [1,2,3,4]} While I have been able to create the key and set its value to an empty array, I've not had any luck in putting any value in that array. objindex:= fb_JBuilder.SetKeyWithArray("Key6", diParentIndex := diRootIndex); objindex2:= fb_JBuilder.SetValue(value:= iValue2, diParentIndex:= objindex); iValue2: ARRAY[0..3] OF INT:= [1,2,3,4]; The two lines of code above produce {"key6": []} . The second line essentially has no effect.

Post by mgengler on Recipe Manager - Not Creating Recipe Files ^{CODESYS Forge talk (Post)}
Recipe Manager will load windows explorer view and allow file name to be typed in or existing file selected but will not create a new file or overwrite an existing. Will not create a file in the default folder or even a defined folder like "c:\recipes\" although it does properly navigate to that folder location. I made sure the folder is not read-only. Can't figure out what is missing...

After creating a Function POU, it is not possible to then create an SFC POU. Steps to recreate: * Create a new Function POU. SFC is not allowed for Functions, so SFC does not show in the Implementation language dropdown. * Click Add Object -> POU... Function is selected for Type. * Select Program * SFC is not present in the Implementation language dropdown

Post by dkugler on Nema 17 Schrittmotor 2.7V kann das sein? ^{CODESYS Forge talk (Post)}
Ein Schrittmotor muss immer an einem entsprechenden Schrittmotor-Treiber/Kontroller betrieben werden. Mit welcher Spannung dieser Treiber versorgt wird(üblich von 5V bis zu 70/80V DC und mehr) und bei welcher Strangspannung der Nennstrom durch die Motorwicklung fließt, ist ein himmelweiter Unterschied. Genau das ist u.a. die Aufgabe des Treibers, die Spannung so zu regeln, dass die Motorwicklungen von dem aktuell notwendigen Strom durchflossen werden. Siehe https://de.wikipedia.org/wiki/Schrittmotor Stichwort Chopperbetrieb.

Post by paro on send appliaction files to wago plc (codesys 3.5) via ssh ^{CODESYS Forge talk (Post)}
Hi, it is enough to copy the files to /home/codesys/PlcLogic/Application and adding the lines [CmpApp] Application.1=Application to the eRUNTIME.cfg, if your Application in your program is also called "Application". Reboot -> Bootapp should be loaded. If not please check the log /var/log/runtime.log There should be a line which explains why the bootproject is not loaded.

Post by bartg on Open a POU in the editor via scripting ^{CODESYS Forge talk (Post)}
Hi, I would like to automate opening some specific pous and visualisations in the codesys environment I found out that I can open it by using : system.commands["42f6acb9-bd6e-42e7-94bb-6e2a03973b83"].execute() But the POU has to be selected in the Devices or POUs navigator. Does anyone know how I can select a specific POU in the navigator? Or how I can open a specific POU? I can retreive the guid of the POU. Thx

Post by greenwood on CODESYS Control Raspberry Pi mit Servotreiber T6 von StepperOnline ^{CODESYS Forge talk (Post)}
Hallo, und vielen Dank für die Antwort. Ich habe 'Modbus_Slave_COM_Port' in eine Watchliste genommen. Leider reichen meine Kenntnisse nicht aus, um aus dem Ergebnis irgendwelche Schlüsse zu ziehen. xBusy und xError wechseln zwischen true und false (im Gegentakt), der angezeigte Fehler ist 'Response Timeout'. iChannelIndex wechselt zwischen 0 und -1. Wenn ich das richtig verstehe bedeutet das wohl, das der Servotreiber auf Anfragen einfach nicht reagiert. Ich hänge einen screenshot vom Watchfenster an, vielleicht kann jemand mehr herauslesen als ich. Nochmal danke fürs Lesen und Überlegen!

Post by kris-samoy on Get Alarm status in Codesys ^{CODESYS Forge talk (Post)}
I am rather new to Codesys and I'm trying to figure out how to get the status of an alarm. This to interlock the start of a device until the alarm has been acknowledged... I am not sure if IAlarm.GetState (METH) can be used for this purpose. If yes then could someone please briefly explain how to use this? https://content.helpme-codesys.com/en/libs/AlarmManager/4.1.0.0/Interfaces/pou-IAlarm/GetState.html Thx & grtz, Kris

Post by swe-hob on call of a method of a function block in another program ^{CODESYS Forge talk (Post)}
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.

Post by hismoon on CodeSys SVN funktionert nicht ^{CODESYS Forge talk (Post)}
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.

Post by culius on Official MQTT-Client: MAX_RECEIVE_BUFFER_SIZE_EXCEEDED ^{CODESYS Forge talk (Post)}
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?

Post by tba123 on Script engine, git checkout, Project Environment ^{CODESYS Forge talk (Post)}
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.

Good morning, The problem I encounter is very disturbing, when I try to connect to my project, it asks me to put in my username and password, which I do. 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

Post by bitwitch on Einheiten umrechnen, Numpad und Eingabegrenzen ^{CODESYS Forge talk (Post)}
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?

Post by nano on How to access to variable value through symbolic string name ^{CODESYS Forge talk (Post)}
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

Post by pmolke on Datenkonvertierung für ein SPS-AO-Modul ^{CODESYS Forge talk (Post)}
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.
