Quick start
The TwinCAT OPC UA Gateway is available for download as a separate setup. The setup automatically configures access to a TwinCAT OPC UA Server running on the same computer as the gateway.
If more than one OPC UA server is added to the gateway, or if the server is running on a different computer, the standard configuration has to be modified. Use the Configurator to configure these settings.
![]() | Configuration of the TwinCAT OPC UA Server Check the configuration of the OPC UA server and make sure that it is operating as expected before continuing. For further information regarding the configuration of the OPC UA Server, read the Quick Start in the chapter "OPC UA Server". |
Quick start – OPC COM DA
To connect an OPC COM DA Client to the gateway, start the client and establish a connection to the following ProgId:
UnifiedAutomation.UaGateway.1

When browsing the gateway, one or more OPC UA Servers will be visible in the namespace of the gateway.

Quick start – OPC UA
The gateway not only offers an OPC COM DA interface, but also allows the aggregation of one or more OPC UA Servers. The gateway also opens an OPC UA interface for this purpose. The gateway can be accessed via the following OPC UA Server URL:
opc.tcp://[HostnameOrIpAddressOrLocalhost]:48050

The namespace of the gateway then contains all underlying TwinCAT OPC UA Servers.
