Software Toolbox Technical Blog

Welcome back to our Summer of IoT blog series! In this third installment, we continue our journey through the fascinating world of IoT, delving deeper into the transformative technologies Software Toolbox has to offer for shaping our connected future. Today, we will be highlighting the TOP Server MQTT Client driver and demonstrating how it can effortlessly integrate real-time data from MQTT brokers into your existing industrial automation systems, such as your HMI, SCADA, MES, or Historian.

Welcome back to our Summer of IoT blog series! We hope that last week’s introduction to the series created excitement as we continue to explore how our IoT solutions can help you achieve even greater success with your Industry 4.0 and Digital Transformation initiatives.

In today's video blog, we will be integrating REST with MQTT by using OPC Router to connect to a RESTful API service and publish data to HiveMQ's MQTT Broker. Although we will use a public webservice to illustrate the concept, the steps we take would be the same for any OT or IT data source that can serve data via a RESTful web service/API.

Welcome to the kickoff of Software Toolbox’s Summer of IoT blog series! Over the next few blog posts, we’ll discuss how our products can play a role in the exciting world of Internet of Things (IoT), but more importantly, how they can be used to further your success in Industry 4.0 and Digital Transformation initiatives. The IoT landscape has grown exponentially over the past decade, transforming industries by connecting devices, systems, and people in unprecedented ways. IoT is reshaping how we interact with technology. At Software Toolbox, we recognize the power of IoT and are committed to providing solutions that facilitate this technological revolution.

Originally developed by the American Heating Refrigerating and Air Conditioning Engineers, BACnet (short for Building Automation and Control Network) is a communications protocol primarily used in building automation systems to control the data exchange between different devices and components. If you're reading this, you’re likely familiar with the building automation and control industry and might have a BACnet controller being used in your industrial process.

In the ever-changing landscape of industrial control, the ability to establish connections and facilitate efficient data exchange between different technologies is crucial. With digital transformation, the industry requires robust integration solutions more than ever before. If you’ve been keeping up with our previously released OPC Router blogs, you're already aware that OPC Router is a flexible middleware solution that provides an array of functionalities for exchanging and integrating data across different technologies. It facilitates seamless interoperability by acting as a connection point between various data sources, protocols, and applications such as OPC DA/Classic, OPC UA, databases, REST, ERP, SAP, and more with a visual workflow editor, templates, and imports for scalable configuration.

If you are new to OPC Router and want to learn more, our OPC Router Learning Resources are a great place to get started.

Knowing when your systems are online and functional is key to the success of your business. In large operations, it could be someone's full-time responsibility to mitigate problems and fix them when they inevitably occur. This makes it critical for the right people to be alerted in a timely fashion so they can take corrective action. To facilitate this need, what if you could also have real-time updates from your process and other systems through email notifications? Rather than rely on human detection and reaction, what if your actual processes and business systems could message you via email when a connection goes down (possibly a critical system is down, or a tank is approaching a critical level)?

In this blog post, we'll cover the steps necessary to use OPC Router to integrate your variety of connections with email notifications, empowering you to stay informed about downtime occurrences and expedite critical decision-making processes for your business.

The TOP Server OPC server is known for its ability to collect real-time data from a wide range of devices, using off-the-shelf industry standard protocols. However, challenges arise when not all devices can consistently share data in real-time due to limitations in connectivity mediums or networks. This is particularly evident in critical SCADA-heavy industries like Power & Utilities, Renewable Energy, Oil & Gas and Water/Wastewater, where precise control of polling is crucial due to their limited bandwidth availability. With traditional cyclic polling, for example "once an hour", you can end up with high bandwidth utilization at the top of an hour and the communications link being idle the rest of the time. Rather than do that, it's better to spread that usage out over the full hour.

The TOP Server Scheduler Plug-In is used to accomplish this spreading out of polling. With it, users can create a customized polling schedule for these devices for any TOP Server driver, which in turn optimizes communications between your SCADA, HMI, MES, or Historian and devices in the field. This eliminates the need to rely on your client applications or direct device configurations to achieve reliable collection crucial operational data from field devices.

Sometimes we are approached by users and integrators with very specific business demands, and an off-the-shelf OPC client solution isn't always the answer to their problems. As they explore the fully customizable development toolkits on the market, they are often concerned that their OPC expertise is inadequate for writing their own OPC client application. How should states and client objects be handled? When would an OPC group need to be created and have items added? What about timeouts, keep-alive intervals and more? Isn't PubSub (as in OPC UA PubSub) a deli sandwich from a popular grocery store called Publix in the US region we live in? Look – we hear you – and its problems like this that Software Toolbox has been solving since 1996. Let's start by saying this up front – you do NOT need to be an OPC expert or understand the internal complexities of OPC connectivity. Our OPC client development toolkit handles all of that and so much more for you. Let's learn more. 

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.
