Hi

I am trying use the Codesys Communication Manager to set up an Opc ua server with a custom information model. As a start I am using the Boiler model available on [Opc foundations github page](https://github.com/OPCFoundation/UA-.NETStandard-Samples/blob/master/Samples/Opc.Ua.Sample/Boiler/Boiler.NodeSet2.xml).  
I am testing with a Wago CC100 and using Codesys V3.5 SP19 Patch 6.

I get the following error:  
**Communication Manager [Device: PLC Logic: Application]: The information model [http://opcfoundation.org/UA/](http://opcfoundation.org/UA/) is required by [http://opcfoundation.org/UA/Boiler/](http://opcfoundation.org/UA/Boiler/) with a minimal publication date from 15/12/2023 but the device has only a model from 15/09/2021 installed. Probably the information model from 15/09/2021 is missing in the information model repository.**

The error message does not make sense to me. Should it not be “Probably the information model from 15/12/2023 is missing in the information model repository”?

Anyway, both versions are available in the repository. How to fix?

Hi @anlebr ,

Please use an older version of nodesets. It is also related to the device description.

Hello, I am working on creating a model and found that I needed to edit the XML after exporting from UA Modeler. I replaced the publication date and version to match the /UA/ model already installed in CODESYS.

PublicationDate=“2020-07-15T00:00:00Z” Version=“1.04”

After editing the XML, I reinstalled the XML in CODESYS and can add the model to the communication manager.

CODESYS SP19 Patch 7 , FW27
