Post by mainak on Opaque NodeId in the OPC UA server ^{CODESYS Forge talk (Post)}
Hello all, I am using the OPC UA server with my custom information model. I have used the communication manager to add my information model under my application and created instances from OPC UA types. I see that the created instances in the OPC UA server has some opaque nodeid (attached screenshot) and I want to change that. Therefore I have the following questions: 1. Is there a way to configure the NodeIds of instances in the OPC UA server? I tried to edit it using the UaExpert client but got error "BadNotWriteable". is it possible to configure it somewhere so that the nodeids can be changed using an external client? 2. Is there a way to define the rule for creating instance nodeids within the codesys IDE? 3. Is it possible to create the instances before e.g. using a modelling tool like UaModeler and import them as part of the information model and use them later? Using the communication manager, I can only create instances from types. I couldn't find a way to map my existing instances to plc tags from my application. It would be nice if someone could help me with these issues. Thanks in advance. :)

Post by joel214 on OPC-UA / Unterschied Symbolkonfiguration, IEC-Symbolveröffentlichung und Informationsmodell ^{CODESYS Forge talk (Post)}
Hallo liebe Community, im Rahmen einer Studienarbeit gilt es ein OPC-UA-Informationsmodell in eine existierende CODESYS-Steuerung zu implementieren. Dabei sind wir auf die Frage gestoßen welcher Unterschied zwischen den folgenden Objekten besteht: - Symbolkonfiguration (veraltet?) - IEC-Symbolveröffentlichung - Veröffentlichung über zuvor erstelltes Informationsmodell In unserem Verständnis erfüllen alle Objekte die Gleiche Aufgabe nur mit unterschiedlicher Vorgehensweise und Darstellung im OPC-UA-Server. Während durch die Symbolkonfiguration die Variablen und Instanzen über lange und verschachtelte Pfade abgelegt werden, wird durch die IEC-Symbolveröffentlichung ein Ordner im Pfad der Objekte erstellt. Dort sind die Variablen und Instanzen anschließend zu finden. Bei der Verwendung von Informationsmodellen hingegen, werden die Instanzen direkt unter den Objekten abgelegt. Für welchen Anwendungsfall ist welche Vorgehensweise am besten? Vielen Dank vorab und viele Grüße Joel

Post by peterned on Programatically restart Codesys OPC UA server? ^{CODESYS Forge talk (Post)}
Hi, I'm using a Festo Codesys PLC (CPX-CEC-C1-V3), which is connected to a HMI panel. Both exchange data via OPC UA. Occasionally, the HMI stops displaying data, and looks as if there is no connection. If the HMI stops, the only way to make it work again is to restart the PLC. Restarting HMI has no effect. When the PLC is restarted, HMI starts working normally again. Is it possible to restart the OPC UA server from PLC code? I hope this will make fixing the HMI possible without a PLC restart. Thanks

Post by alimans on OPC-UA Server, Symbol Set: Raise an error: Object reference not set to an instance of an object. ^{CODESYS Forge talk (Post)}
Hi everyone, I just created a very simple library without any code and, added it to my very simple project. after adding this library, I get an error when I try to open "Symbol Set" in "OPC UA Server" in "Communication Manager". Here is the code of my POU in the library: FUNCTION_BLOCK POU VAR eCommand : (CMD_NONE:=0, CMD_RESET:=-1) INT := CMD_NONE; END_VAR Attached is the error that I get. I also noticed that by removing the enumeration variable above (eCommand), I can open the "Symbol Set" again. Anybody has any idea why this error is raised and how could I use enumeration variables without error in "OPC UA Symbol Set"?
