Post by mdetrana on VPLCs Tab 'Grey-ed Out', Cannot Create VPLC ^{CODESYS Forge talk (Post)}
When evaluating Codesys functionality, I found that the VPLC tab under Deploy Control SL > Operation > VPLCs is 'grey-ed out', see attached image. I'm trying to evaluate how my infrastructure will interact with Codesys on a Raspberry Pi 4, so I'm trying to demo running it before purchasing licenses. I was going through the Codesys tutorial here, and it never shows the tab as grey, so I do not know how to proceed. Let me know if I can get any additional information that can help. This could be related to an Info message that's sent when connecting- [INFORMATION] Connected successfully! [INFORMATION] Successfully connected to target (<ip_address>) [INFORMATION] No supported container engine found on device. You have to install a supported container engine to use Virtual Control. Please contact the Administrator of the device. [INFORMATION] Finished reading device information</ip_address> I'm not exactly sure what I would need to do to install a 'supported container engine'.

I have to enter the owner password from time to time, even though I haven't closed the project yet. Is there a way to disable this option? So I only have to enter it once when I log in to the project, and that's it.

Post by marsmaennchen on MQTT,mehrere Topics publish/subscribe ^{CODESYS Forge talk (Post)}
Hallo zusammen, ich habe im Grunde dieselbe Frage wie in diesem Thread: https://forge.codesys.com/forge/talk/Deutsch/thread/85372a6daf/ Leider hat der Threadersteller das Problem selbst gelöst, ohne seine Lösung zu teilen. Mein Setup: Ich möchte von einer WAGO PFC200 Daten per MQTT an HomeAssistant übertragen. Die Grundkommunikation steht bereits. Angenommen, man hat 50 Lichtschalter und 50 Lampen. Wie ist das übliche Vorgehen, um 50 einzelne Bool-Werte (Lichtschalter ein/aus) effizient zu übertragen? Ich finde einfach kein Beispiel, das ich als Vorlage nutzen könnte. Muss wirklich für jeden Lichtschalter ein eigenes MQTT-Topic und somit ein eigener Baustein in CODESYS angelegt werden? Also z. B. Topic/LS1/state, Topic/LS2/state usw.? Oder gibt es eine gängige, professionellere Methode, mehrere Schalter effizient zu übertragen? Zur Eingrenzung: Ich nutze die CODESYS IIoT Libraries, da die Janz Tec MQTT Library für mich bisher zu komplex ist. Kann mir jemand bitte erklären, wie Profis so etwas lösen? Vielen Dank schon mal für eure Tipps! Gruß Patrick

Post by cihangur on C0138: No matching 'FB_Init' method found for instantiation of VisuClientObjectMgr ^{CODESYS Forge talk (Post)}
This "FB_Init" error has become very annoying lately. It's usually related to webvisu and is resolved by deleting all objects and related libraries. Of course, you need to re-add the deleted objects. Lately, we've generally been managing by not upgrading, but this problem persists in every version since SP20 and should be resolved. I updated a project from SP 19 to SP 21 and found 116 similar errors. [ERROR] alarmmanager, 4.7.0.0 (intern): ReplaceAlarmPlaceholdersConverted: C0138: No matching 'FB_Init' method found for instantiation of CharBufferString [ERROR] visuelemsalarm, 4.7.0.0 (system): protDrawRowHeader [VisuFbElemAlarmTable]: C0138: No matching 'FB_Init' method found for instantiation of CharBufferString [ERROR] alarmmanager, 4.7.0.0 (intern): AnalyzePlaceholders2 [Alarm]: C0138: No matching 'FB_Init' method found for instantiation of CharBufferString If you have an ERROR related VisuClientObjectMgr you can try to disable "Visualization Manager - Settings - Support client animations and overlay of native elements " selection "C0138: No matching 'FB_Init' method found for instantiation of VisuClientObjectMgr" etc

Post by rene2 on How can you get the active frame index from a frame ^{CODESYS Forge talk (Post)}
I think I struggle with the same issue. I tried the currentVisu variable but this is the active Visualisation. I have a dialog with a frame with frame configuration like in the picture. I would like to use the index te be used to make a button look like it's pressed/selected.

Hi Everyone, As we didn't have client for IEC - 104 - only server server is available , so because of that we are trying to make establish the communication between the external simulator as a Client and codesys itself as a server. We are looking for the variable behavior from CODESYS has to change according to the message triggered by the CLIENT (we are using simulator Application like Redisant). We are able to see the log data as the status of triggering the SCS from Client received to the Log data of the codesys device(attached screen shot of it) and in simulator panel we had set the details to trigger the data from Redisant to Codesys. Current Status: The project builds and runs successfully, but I need guidance on how to connect this to an external IEC-104 simulator for testing and visualization by using demo mode.
