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.
Logging OPC Data with Custom Time Formats

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.
Exploring MQTT – Understanding Quality of Service (QoS) with DataHub

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.

If you’re an existing user of OPC Data Logger or in the market for an OPC logging solution, you likely agree that having a reliable and accurate record of your data is a top priority. One of the most valuable parts of investing in a data logging solution is being able to trust that all the data from your sources is captured. But what happens if you lose the connection to your database? What happens to the incoming data during that downtime? Software Toolbox offers several solutions for logging data and today we will focus on OPC Data Logger and its database logging capabilities.
Tech Support Corner: Using TOP Server Simulated Device Mode

If you're a TOP Server user, you're likely accustomed to connecting to a device configured in TOP Server that is sending real-time data through one of its many available drivers. But did you know you can setup devices in a "Simulated" mode for a variety of client testing purposes when a live device isn't available?
Continuing our Tech Support Corner blog series, this post covers how the "Simulated" device property works, why you might implement it into your testing and a brief walkthrough on connecting a variety of client applications to a simulated device in TOP Server.
