Post by jzhvymetal77 on IecVarAccessLibrary.IBaseTreeNode methon ^{CODESYS Forge talk (Post)}
I got this code working again. 3S/CoDeSys, your level of obfuscation and lack of documentation turns a simple task into a monumental complex challenge. The issue was that at some point the IecVarAccessLibrary changed and no longer allowed using IBaseTreeNode to retrieve a child or the number of children. The attached code has been updated to use IIecVarAccess6.VarAccBrowseGetChildByIndex instead. The code was also cleaned up but is still a work in progress. The current example only works one layer deep. This means native data types, arrays, and single-layer structures are supported. However, structure arrays and nested structures are not yet supported.

Post by preimesbergert on Raspberry Pi 4 B HW 1.5 Codesys control 4.10.0 stopps after a few seconds ^{CODESYS Forge talk (Post)}
Wanted to play a bit with a raspberry Pi 4 Model B HW 1.5 and Codesys. Regardless of the image (tried 32bit / 64bit version from Raspberry Pi Imager) and with all tested Codesys Control versions (4.2.0, 4.8.0, 4.10.0) and regardless if single core / multicore / 64 bit variant, always is the runtime stopped after about 30sec with the nice message: ooops... this runtime was built for RASPBERRYPI. Hardware version or firmware version not supported! (-7, 0x00000BB8, 0xFFFFFFFB) Whats wrong with it?!?!? I read a lot about the issue in topics from 2020-2021 but it always was stated with new Codesys control version issue will be fixed (4.4 for example) but still it is there.

Post by sebastian-hk on Codesys auf einen Cortex M4 lauffähig machen ^{CODESYS Forge talk (Post)}
Hallo, wir spielen mit dem Gedanken, Codesys auf einen AT SAM E54 Xplained Pro lauffähig zu machen. dieser besitzt einen Atmel ATSAME54P20A mit einem Cortex M4. Meine Fragen hierbei: Was muss portiert werden, wenn die Zielhardware momentan noch nicht unterstützt wird? Gibt es ggf. Anleitungen, um die Laufzeit auf solch einen Controller zu bringen? Muss hierbei ein eigener Interpreter entwickelt werden, der den compilierten Code "übersetzt"? Wie lauffähig ist der rübergespielte Code, gibt es irgendwelche Einschränkungen bei der Programmierung in Codesys? (Verwendung von bestimmten Datentypen nicht möglich?) Was für Lizenzen werden für den Controller benötigt? Vielen Dank im Voraus Sebastian

Post by ewi04 on Recipe Manager - RecipeManCommands, load & write wrong values, Bug? ^{CODESYS Forge talk (Post)}
Hello, according to Codesys, the problem should be solved with version 4.3.0.0. After the update to version 4.3.0.0 I had the problem that the recipes weren’t saved correctly, but loading was okay. Return to the version 4.2.0.0 didn’t change the behavior. Strange… So I uninstalled the update, cleaned the project and built it new. The known behavior of version 4.2.0.0 was back. Update to version 4.3.0.0, clean and build it new, it works. Even with version 4.2.0.0. Strange, but okay. Notice: ManCommands.LoadRecipe() no longer writes into the PLC. Just as it should be. As of now, I can use the new version.

Post by eschwellinger on Zielsystem stimmt nicht mit dem verbundenen Gerät überein ^{CODESYS Forge talk (Post)}
na ja es gibt halt einfach die Möglichkeiten: 1. Man installiert Raspberry PI OS 32Bit -> dann geht PI SL und PI MC Multicore als Target 2. Man installiert Raspberry PI OS 64Bit dann muss es PI64Bit sein falls der Übersetzungsfehler nicht in einer Bibliothek ist (die du vielleicht nicht ändern kannst) https://faq.codesys.com/pages/viewpage.action?pageId=128253958 Hier der Hinweis was man tun muss das dein IEC Code für 32Bit als auch 64Bit Targets funktioniert Also entweder zurück auf Raspberry PI OS 32 Bit: nur zur Info noch was im Config file steht für welche Plattform/Produkt [CmpRasPi] Architecture=aarch64 (-> 64Bit PI) oder Architecture=armv7l (-> PI MC Multicore) oder Architecture=armv6l (-> PI SL Single Core)

Post by mp9876 on Device User Logon ^{CODESYS Forge talk (Post)}
Following up on the invalid user authentication on the target Not 100% sure what the problem was but following my post I managed to create an administrator level user. Then my next issue was that I could not connect to the device. I might have flipped the device from a 64 bit version to a 32 bit version so I did UPDATE DEVICE back to the 64 bit version; still could not connect somehow. Then I did two things at the same time that fixed my problem: Wiped the Codesys Control Win 64 bit version and installed the 32 bit version Installed latest Codesys Control Win V3.5 SP20 (released today) I wish I knew which one of these actions fixed the problem but at least the problem is solved. Hoping this post may help someone one day

Post by reinier-geers on License problem gateway ^{CODESYS Forge talk (Post)}
Epis doesnt want Softmotion. I thought it was about the price. If it was possible it would be working already and i dont need an extra licence. Thats the problem of codesys. The software is running but hangs on its license. Epis made it posible to see the stick. I can see the license. Softmotion is there from 3.5.14.Xx Like is said And Motion control is alrady posible 15 year ago. And i only need a Sync of 2 drives. I want a good solution not a refund. Dont point to the manufacturer. The software is made by 3s not by epis .

Post by salvadegianluca on SysPlcCtrl23 and C0338: The library 'cmperrors interfaces, 3.5.5.0 (system)' is supported just in 32 bit applications ^{CODESYS Forge talk (Post)}
Good afternoon to everyone; I'm stuck with this error and I don't know how to get out from it... I tried several time googling for alternative systems to control the PLC applications and resets but without success. I would like to realize the possibility to reset the CPU and to start/stop the applications as it was possible with the SysPlcCtrl23, but this library is no longer supported in 64 bit systems and it seems due to the cmperrors interfaces sub library that was included in the above said one. Someone found a work around for this issue?

Post by pernockham on Unable to deploy "Control for Linux SL 4.18.0.0" ^{CODESYS Forge talk (Post)}
The option to update "Control for Linux SL" is not shown in the "deploy control SL tool", I can see and update the gateway but not the control (3.5.21 SP4). Has the way to update control SL changed? In the process of fault finding I removed the control SL entirely from my target, then I had to revert to version 3.5.21.0 SP 1 to re-install "Control SL 4.17.0.0". So I thought it was just a matter of using SP1 to update also to 4.18.0.0, but after installing the files for 4.18.0.0 in the SP1-version, the behavior was identical to SP4, ie no Control for Linux SL shown in the deploy tool.. See screenshots.

Post by manuknecht on Detect "Cancel" Press in FileOpenSave Dialog ^{CODESYS Forge talk (Post)}
Thanks for your response! It seems like the VisuElems library has updated functions to the ones you used but apparently these older ones still work, even if I couldn't find them in the library documentation and they are also not suggested automatically by Codesys (when using Ctrl + Space). However, its precisely what I was looking for and it works. Thanks!

Post by derpaul on Official MQTT-Client: MAX_RECEIVE_BUFFER_SIZE_EXCEEDED ^{CODESYS Forge talk (Post)}
Hello, my PFC200 has run for a few month now without problems. But now it freezed 2 times a day. LEDs were green but the PLC was not reachable. After power off -> on. I found that the MQTT had an error: MAX_RECEIVE_BUFFER_SIZE_EXCEEDED. And MQTT hadn't reconnect since then. I tried a cold and a warm reset but nothing helped. How can I solve this? Regards, Paul

I've post the Versions in the Attachments. It seems with htop, that there is a very high CPU Load. In the Log I can see nothing, as mentioned above I've to restart the PLC with Power off/on and the log in codesys was deleted. Or what do you mean with plclogger?

Thanks for your responses. The close listener sounds like an interesting approach, will have to see what I can do with it. I actually solved it as suggested by sturmghost by setting an enum variable to a certain state as soon as I open a dialog. This way I always know which dialog was opened last.

Hallo zusammen, seit dem Update des Packages Codesys LB/FBD von Version 4.2.0.0 auf 4.3.0.0 bekomme ich beim compilieren folgende Fehlermeldung (siehe Screenshots). Hat jemand eine Idee was die Ursache sein könnte? Der rechte Baustein ist eigentlich ein FB aber die Instanz wird beim compilieren einfach entfernt. Edit: Wenn ich die Ausführung des rechten Bausteins in einem Execute mache, dann wird fehlerfrei compiliert.
