<div class="markdown_content"><p>Hello @ <a href="https://geometry-dashscratch.com" rel="nofollow">geometry dash scratch</a>, <br/> 1. In OPC UA, NodeIds are supposed to be stable and unique, but in CODESYS the runtime usually generates them automatically for instances created via the Communication Manager. That’s why you see those “opaque” / numeric NodeIds. <br/> 2. What you can do is control how your application variables are mapped into the OPC UA address space (via symbol configuration). Those NodeIds will usually follow the namespace and symbol path, which is more readable.<br/> 3. Yes — this is the more structured approach. You can create ObjectTypes, VariableTypes, and instances directly in UaModeler, export them as NodeSet2 XML, and then import that XML into CODESYS as an information model.</p></div>

<div class="markdown_content"><p>This seems to be because when creating 'OPC UA' with 'Communication Manager', the 'IdentifierType' of 'NodeId' cannot be configured as' String 'type. This issue is not an isolated case. For this issue, CODESYS seems to have not provided guidance to users on how to proceed. We can provide feedback on this issue in the 'My Question' section of the 'CODESYS Store' to make CODESYS take it seriously.</p></div>

<div class="markdown_content"><p>Same for me. I have problems with UAExpert too. <br/> Can't see the Current Value of Enum and can't control. <br/> Did some Tests with Python opcua library. Not working with the communication manager so far. </p></div>
