Using MQTT to Stream OPC data to Digital Twins in Azure IoT Hub

3 min read

Cogent DataHub is always expanding its wide range of flexible connectivity options between different data sources such as MQTT, OPC UA, OPC DA, ODBC, DDE and so much more.  With the advent of IIoT and its increasing adoption across industries, connectivity to various traditionally non-IIOT data sources via MQTT is key.

If you're not familiar with the concept of a virtual or digital twin, it's the idea of virtual modeling a physical asset or system.  Ultimately, the key motivators for creating digital twins is having the ability to accurately model and predict what will happen with the real-world physical equivalent of that digital twin.  Digital twins are extremely beneficial towards predictive analytics used for pro-active maintenance and process optimization across industries.

In this next installment of our Cogent DataHub Virtual Training series, we will cover step-by-step how to easily connect and push data from OPC data sources to digital twins in the Azure IoT Hub including how to optionally do so through a network DMZ (DeMilitarized Zone) using an additional DataHub as a proxy server for even greater security.

Video How-To: Connect Non OPC-UA Clients to UA Servers with TOP Server

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.

Tech Support Corner: Protecting Your TOP Server OPC UA Process Data

6 min read

By Tyler Lindsey on May 14, 2020 2:00:00 PM


With the rising security demands of Industry 4.0, OPC UA provides us with the means to encrypt data as it is transferred between client and server. But what if encrypting data to prevent outside extraction is not enough? What if UA client applications become compromised? What tools do we have to protect against deliberate or even accidental manipulation or consumption of data?

Continuing our Tech Support Corner blog series, this post covers how to leverage the built-in TOP Server User Group Security settings, alongside OPC UA username and password authentication, for greater control over which users have read/write capabilities as well as what tags a user is permitted to access.
