Installation
- Sign in with an account permitted to install software.
- Right-click the setup file and select Run as administrator.
- Verify the publisher and confirm the Windows security prompt.
- Follow the installation wizard.
- Keep the proposed installation folder unless your system policy requires another location.

C:\Program Files\IBH OPC UA Server-Client
The setup installs the ibhopcua service, IBHOpcUATray.exe, the server/client runtime, the Web Configurator and Start menu entries.
Check the service and tray
Open services.msc. The IBH OPC UA Server-Client service, internally named ibhopcua, should be present and start automatically.
Administrative PowerShell commands:
Get-Service ibhopcua Start-Service ibhopcua Restart-Service ibhopcua

The tray application provides access to start, stop, the Web Configurator and diagnostics. If the icon is missing, start IBH OPC UA Server-Client from the Windows Start menu.

Open the Web Configurator
Open it from the tray menu or use:
http://localhost:48080
From another computer:
http://IP-ADDRESS-OR-HOSTNAME:48080
For an unchanged initial installation:

MQTT, the integrated OPC UA Client and online activation may require additional outgoing connections.
License activation
The former hardware-ID, email, serial-number and PIN workflow is no longer current.
Online activation
- Open System / Licensing.

OPC UA connection test
opc.tcp://IP-ADDRESS-OR-HOSTNAME:48010
Add the endpoint to an OPC UA client, verify the server certificate, select the matching security policy and authentication, browse the address space and read a test variable. Write only to variables explicitly intended for testing.
