Integrate external information models
This guide is based on the Process Automation Device Information Model (PA-DIM), a companion standard used in the process industry. For other information models the procedure would be similar.
-------------------------------
I’m using UaModeler from Unified Automation and created a very simple NodeSet that only contains some basic data types (Int, UInt, String, Bool, Byte).
I saved the file under:
/opt/plcnext/projects/Default/Services/OpcUA/NodeSetsThe new Address Space appears in UAExpert , but the data nodes for the basic data types (one node per type) are not shown.
I’m quite new to OPC UA, and after some debugging I found two possible issues:
The RequiredModel http://opcfoundation.org/UA/ on the PLCnext has version 1.05.02 , while in UaModeler it’s already 1.05.05
- .
- In the tutorial, the new instance is mounted under “DeviceSet” , but in my XML it is directly under “Objects”.
Could either of these be the reason my project isn’t working? Thanks for any kind of help.

Project background:
We’re using WebIQ for HMI development.
Our goal is to create templates for the HMI — for example, a “room” template with data points for A/C, lighting, etc.
I want to create a custom Information Model and import it into PLCnext.
After the PLC program is finished, I’ll just need to map the OPC UA nodes.
This way, HMI and PLC development can be done separately and in parallel.
