Secure data transmission between the Operational Technology (OT) and Information Technology (IT) layers is a critical concern in industrial automation. Traditional methods often expose critical systems to vulnerabilities by opening ports on the OT level when leveraging standard OPC deployments. While OPC UA has streamlined industrial communications by eliminating the complexities of DCOM configuration and its associated security risks, the continued use of open ports still leaves potential vulnerabilities for attackers to exploit.

DataHub Tunneling has often been viewed as just another way to bypass DCOM or an alternative to OPC UA, but it is much more than that. In this blog post we’ll explore four ways Cogent DataHub, a versatile middleware software solution, can address these security challenges by leveraging its advanced tunneling capabilities and more.

Welcome to the next installment of our Data Storage Deep Dive series! For years, Software Toolbox has been synonymous with terms like “device connectivity” and “data integration” thanks to our variety of connectivity solutions that help collect real-time data for all your industrial automation operations. Beyond just real-time data, our team recognizes the value of historical data within the industry, and we aim to help businesses make larger data backed decisions over time.

Continuing our Summer of IoT blog series, we'll delve into the exciting new release of Cogent DataHub V11. For those that may have missed our previous post on Cogent DataHub V11 Features to Be Excited About, the entirely revamped security profile provides a Secure out-of-the-box experience for V11 users that opens a variety of customized options. Today we take a deep dive into a part of the security improvements, and next month we’ll take a second deep dive into security.

As we continue our Summer of IoT blog series, this week we'll turn our focus to the V11 release of Cogent DataHub, a powerful platform known for its ability to seamlessly connect to a wide range of data sources including OPC, databases, MQTT, and more. DataHub Version 11 builds upon this foundation, empowering users with enhanced security, improved usability, and expanded connectivity options. This blog post dives into the key new features that make V11 a significant upgrade over its predecessors.

Cogent DataHub enables users to integrate diverse data sources quickly and efficiently within their industrial automation ecosystems. By providing multiple ways to consume, organize, and deliver data, handling multiple inputs is a strong suit of DataHub.

CSV import functionalities are available for a variety of plug-ins including OPC DA & UA Clients, MQTT Client, External & Local Historians, Bridging, and Modbus. In this blog, we'll delve into the format and import options of OPC UA items specifically tailored for DataHub's OPC UA Client configuration, but the concept is the same for all CSV imports in DataHub.

When logging data to a database or text file, the way that data is presented is essential due to the implications it has for who, or what, is reading this data to make decisions. Without the correct configuration of the data’s timestamps, records can easily become misinterpreted or sorted in non-chronological order by further systems. It’s critical that your data logging solution provides flexibility to get your data when you want it, how you want it, and stored the way you want it. Providing full control of the timestamp format for many users is not just a feature of our OPC Data Logger, but a requirement based on other connected systems and standards. Customizable Time Formats is the focus of today’s blog, but it is just one of the OPC Data Logger’s many flexible features that have our fans raving over it.

MQTT continues to grow in popularity and implementation within the industrial automation community. For those who are still new and learning about this protocol, MQTT is a light-weight transfer protocol built around a publish/subscribe architecture. In simple terms, MQTT can be compared to a mail envelope, providing structure and a common appearance with a supported delivery system, while the actual content of that envelope can vary widely.

Because of the ambiguity of message content, implementations of MQTT can be utilized for various needs across segments in our industry, though the varying message content presents its own issues that are outside the scope of this article. There are multiple solutions for providing structure and standards around the message content that we will discuss in future posts.

This blog will primarily focus on the reliability of message delivery based on the concept of Quality of Service (QoS). We will be utilizing the Cogent DataHub to showcase these options, as it can act as both the MQTT Broker & Client. It is important to note that this information can be applied to various MQTT implementations, including other Software Toolbox product offerings with MQTT, such as OPC Router or the TOP Server MQTT client driver.

Storing process data almost always comes with varying project requirements, making it difficult for users to find solutions that cater to specific configuration needs. Luckily, the wide variety of configurable functionality in OPC Data Logger allows for creating unique projects to fit your needs.
