Issue
This is related to PO2021 as OPCUA server.
It was observed that no objects (tags from PSO) found when connected EPO OPC UA server with 3rd party OPC UA client (Ex: Matricon OPCUA exploer)
Notice in below window do objects under 'BrowseProvider'
But for objects under 'Server' is working well:
Also you might observe below error when double clicked on 'BrowseProvider'
Environment
EcoStruxure Power Operation (EPO) 2021
Matrikon OPC UA Explorer
Cause
Under the below circumstances you may observe this issue
1> In a single cluster machine, if computers DNS Name is not configured in the project.
2> In a Multi-Cluster project with several computers, only the first computer defined DNS Name in the project and other computers are empty..
3> If primary networking model for the PO machine is selected as 'Stand alone'
Resolution
1. While defining Computers in the project, each computer must have a DNS Name which should be the Windows computer name (or localhost if you are running on a standalone computer), which is used for validating security certificates.
To know windows computer name: Select Start > Control Panel > System > About >Rename this PC (Advanced)
2.Accordingly configure the Network Addresses > Address filed (with IP address or windows computer name), if in case machine has multiple network cards add a network address for each card in each computer with its IP address which you want to communicate.
Note: "Localhost" and a fully qualified domain name (complete domain name for a computer) are not supported.
After this save the project and compile.
3. Open the Computer Setup Wizard > Network Setup > make sure to select "Networked"
Now in the OPC Clietn tool, we can find the corresponding objects under ‘BrowseProvider’
