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. :)

One workaround is to create a second application which is started after the rested of the main application. The second application starts the main application after time x and is rest after done start of the main application. No problems during the fieldbus re-start by this workaround.

Post by sachem on SysFileGetTime problem ^{CODESYS Forge talk (Post)}
Good morning. I'm working with a Weidmuller controller using Codesys. My project use OPC-UA to communicate an application in my pc with the controller. Yesterday, I installed the license of the controller and test it, and the communication works perfect. I use the communication with anonymous login, and works fine. But, hours later, the anonymous login don't work, and the controller only allows connection via OPC with username and password. Someone know why this happend? Thanks
