While TOP Server for AVEVA™, formerly Wonderware provides connectivity to hundreds of device types and protocols, that is only part of how TOP Server helps with integrating industrial process data with external software such as AVEVA™ System Platform, formerly Wonderware and other client applications.

You're likely aware that TOP Server is an OPC UA server.  But TOP Server can also act as an OPC UA client for integrating with other OPC UA servers, as well.  For situations where you have a UA server to integrate but your client does not support OPC UA, but does support one of TOP Server's other client interfaces, TOP Server can be the gateway solution. This is especially valuable for AVEVA users who wish to keep using AVEVA Suitelink, OPC DA, or have not migrated to a version of AVEVA applications that support OPC UA Client functionality. 

In this video blog, I'll show you how to make a secure OPC UA connection from TOP Server to other OPC UA servers supporting the Data Access profile.  We cover the basics of configuring the OPC UA Client driver in TOP Server and making an OPC UA connection to another OPC UA server.

In addition to the hundreds of devices and protocol types that TOP Server can connect to with its available drivers, TOP Server can also connect to other OPC servers via the TOP Server OPC Client Connectivity Suite, including OPC UA (Data Access Profile) servers.  There are a number of key use cases for the OPC UA Client driver that we've discussed in detail here.

Watch this video to learn how to connect TOP Server to any OPC UA (Data Access Profile) server application, including basic setup, for integrating other systems accessible via OPC UA. In this example we'll connect to our own OmniServer as an OPC UA Server. Looking for other how-to videos for TOP Server?  Click here!
