The new updates provide developers of custom OPC client applications new options to interact with even more OPC UA servers or more richly with existing OPC UA servers. This blog post teaches you how OPC UA PubSub security is different from regular OPC UA security, how to improve JSON/OPC UA PubSub interoperability with a new utility, and why you might care about OPC UA File Transfer.

In our ongoing Exploring OPC UA blog series, we have shifted the focus from general concepts about how OPC UA certificates and security work to looking at practical usage of OPC UA in specific Software Toolbox solutions. Last time, we focused on configuring TOP Server for OPC UA connectivity.
In this fifth post of the series, we will focus on OmniServer, our solution for getting data from non-standard devices into OPC UA and other client applications. We'll step through what the settings are in OmniServer and how to get your OPC UA client applications connected.

So far in our ongoing Exploring OPC UA blog series, we have primarily taken a general look at OPC UA Certificates and security and how they are used by OPC UA clients and OPC UA servers to keep industrial data secure.
In this fourth post of the series, we take the series down a more specific path by starting to look at the settings and configuration of OPC UA for specific Software Toolbox solutions. This post focuses on TOP Server for AVEVA. We'll step through what the settings are in TOP Server and how to get connected both for your OPC UA client and servers.

Developers of custom OPC client applications have new options, enhanced troubleshooting tools, runtime configuration flexibility, and improved utilities to help them in the recently released 2021.1 (5.60) version of the OPC Data Client Toolkit.
In this technically hot blog post, we will cover the release highlights with links to documentation, and, as always, the full detailed release notes are available in our knowledge base. Also if you did not see the 2020.3 (5.59) release post, that one was packed with technical details.

While the recent winter storm in Texas and its rolling energy shortages has brought the subject of the availability of affordable energy and deregulation of power markets to the forefront of the conversation, this has been a problem in many areas of the world for a long time. This is mainly because of the large fluctuations in the price of energy that both residents and businesses have to endure.
It's ultimately the law of supply and demand driving such issues - when energy supply is eclipsed by extraordinary demand for it, an inconvenience during the best of times becomes a crisis in the case of extreme situations such as unexpected winter weather, devastating storms, hotter than normal summers and other unpredictable situations.
In the case of manufacturing and other industries that rely on energy as an input for operations, the cost of energy can literally determine whether a production run is profitable or not. This post discusses methods for monitoring energy costs in real-time from your HMI, SCADA or MES system using OPC UA or OPC DA, for decision support to prevent avoidable losses.

IoT, IIoT, MQTT, Connectivity of Things, Big Data, The Cloud - I'm sure you've at least heard these terms in the course of your day (whether in the scope of your job or in an advertisement during a football game you happen to be watching). Maybe you're even working on a project requiring you to push and/or pull important process or business data to/from a cloud solution - possibly for big data analytics applications ranging from predictive maintenance to "smart" manufacturing, amongst many other use cases.
And Amazon© - well, I'd wager there isn't a single person out there who doesn't know who Amazon is. But did you know they have their own cloud solution called Amazon IoT Core©? And maybe you didn't also know that Amazon AWS (Amazon Web Services©) IoT Core acts as an MQTT broker for storing and sharing important data in a secure cloud along with artificial intelligence and analytics and many other IoT services.
But how do you go from your data sources to AWS IoT Core? In this post, we'll step through how you can configure "things" in Amazon AWS IoT Core and connect them to your process and business data sources with the Cogent DataHub IoT Gateway©.
