Software Toolbox Technical Blog

Today's industrial automation users have a need for fast, responsive, easy-to-configure Human Machine Interfaces (HMI) that can economically deliver a rich user experience and make sure critical plant production information can be securely accessed by everyone in their organization from anywhere at any time.

Cogent DataHub® WebView™, a feature offered within the Cogent DataHub IT/OT data integration software, is an advanced HMI solution tailored to seamlessly integrate with your live data streams and eliminate any delays typically associated with HMIs that are dependent on databases. As a comprehensive solution that combines real-time data delivery, a robust web server, and an HMI designer into a self-contained package, DataHub WebView provides an excellent alternative for those seeking a cutting-edge HMI for process monitoring without committing to a significant investment in a complex SCADA system.

DataHub is a solution in Software Toolbox’s portfolio of software that integrates various IT and OT data sources, and is particularly strong in working with a wide range of OPC standards, secure multi-layer data tunneling, databases, historians and more. If you've ever worked with DataHub, you've probably seen the "Scripting" tab shown in the image below with some sample scripts. Perhaps you've wondered what this scripting can do or were curious about the language that DataHub scripts use. With that in mind, in this week’s blog we will cover the "what" and "why" of scripting in DataHub, and point you to "where" you can find more resources of "how" to take advantage of the DataHub scripting engine, included free with all DataHub licenses.

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.

Round-trip InfluxDB Integration using OPC Router

Software Toolbox offers a variety of tools for integrating with InfluxDB.  Today we focus on OPC Router, a solution that enables visual workflow integration of traditional OT data sources with time-series databases such as InfluxDB.  The InfluxDB connector provides for reading and writing to InfluxDB (local or cloud-based). OPC Router's workflow engine provides visual data mapping, for ultimately extracting analytics and results from InfluxdB and making them available to the plant floor in OPC UA (or other) format.

In a prior blog post regarding redundancy, we learned how critical it is to plan for redundancy in the Industrial Automation space. We covered how the TOP Server Media-Level Redundancy Plug-In  facilitates duplicate or backup systems used to maintain reliable communications with the critical components in your environment which in turn minimizes data loss and increases the availability of your critical industrial data.

If you're a SLIK-DA/UA OPC Server development toolkit user with your own custom OPC UA Server applications or have worked with any of our other OPC UA enabled solutions, you may have noticed properties or configuration options in your software by the name of Local Discovery, Discovery URL, Discovery Servers, or Discovery Domain. Clearly, there is a recurring theme here of “Discovery”. Taking this even further, you may also have a Windows Service running on your PC called “OPC UA Local Discovery Server” (LDS), but we often encounter users who don’t know what a UA Discovery Server is, how to leverage it with their custom SLIK-DA OPC UA Servers, or why they should even consider it. Proper usage and implementation of an OPC UA Discovery Server will make it easy to find and connect to your UA Servers from your UA Client software applications such as HMI, SCADA, MES, & Historians if they also support OPC UA Discovery.

Tags, nodes, points, items, symbols – in our industry, we often see these terms thrown around, but in most instances, we’re all talking about the same thing. From the TOP Server OPC Server's perspective, we refer to them as tags. A tag is an OPC Server software application’s representation of a device address to use for communication. This is how your HMI, SCADA, MES, historian, or other client application is able to consume data. If you’re a TOP Server user, you know that you are required to configure tags to get data from your device, but did you know there are multiple options of how to accomplish this?

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.
