Overview

This manual is an online reference and also contains general information about how to use the UaGateway. Please read the Introduction to UaGateway first before you start.

The UaGateway is a high-performance wrapper and proxy for easily migrating “classic” OPC products to the “new” OPC Unified Architecture (UA) technology and vice versa.

Using the Configuration Tool (UaGateway’s OPC UA client), connections to OPC UA, COM AE/DA/HDA, and XML-DA servers can be added. The address spaces of these underlying servers are mapped to the address space of the UaGateway’s OPC UA server. Thus, OPC UA clients can access the information provided by “classic” OPC servers. Moreover, the UaGateway can be used to aggregate information and serve as a single point of access.

In addition to that, the UaGateway contains an OPC COM DA and an OPC COM AE server. It’s possible to configure connections to underlying UA servers and make their information available to “classic” OPC Clients.
