Node-RED: The IoT Programming Language No One is Talking About
Sussing out the key pieces of the Internet of Things is usually accompanied by caveats ranging from the established uncertainty of the future, the security problems of the present, and the legacy system integrations of the past. Industry gurus and thought leaders predict growth in the billions – dollars, devices, deployments, Cloud applications, etc. Networking experts waffle on standardization. Hardware providers sprint to keep up. But one of the critical pieces of the Industrial IoT is something you won’t find jumping off front-page headlines – yet: Node-RED, the programming tool for wiring together hardware devices developed by IBM, is the power behind the IoT throne, and no one is really talking about it. Lost amid the noise about ‘smartifying’ the world is the practical reality that unless you can figure out a way to seamlessly connect the hardware devices that comprise a smart network, you are essentially relying on the Cloud to run an overwhelming number of disparate applications – and that is assuming your network is near invincible. Since the Industrial IoT relies, in theory, equally upon Cloud and Edge device processing, developing software applications that can effectively run in both settings is crucial. This is where Node-RED comes in. According to Nodered.org, the open-source Node-RED ” … provides a browser-based editor that makes it easy to wire together flows using the wide range of nodes in the palette that can be deployed to its runtime in a single-click … [making it] easy to wire together flows using the wide range of nodes in the palette.” The essence of this tool is that engineers and operating technicians can create and configure applications easily, in real time, on Edge devices. Ideally, the pieces of code being used to create programs are reusable, meaning that the process can be learned by field operators without the need for a degree in computer science. The code is built on Node.js, the JavaScript runtime that frequently pops up on Raspberry Pi platforms due to its ease of use. So, if it is so easy, and so important, why is no one talking about it? The ongoing problem for the IIoT is the Wild West mentality: the no-holds-barred land grab has resulted in disparate hardware and software products that often require a combination of proprietary and open-sourced solutions. As a result, the actual mechanisms that drive the building of an IIoT network are often less talked about than the tangible pieces that come together to build that network. There are several considerations to keep in mind. First, the idea of IT/OT convergence has only just started to gain traction, so legacy solutions (especially in certain industries) haven’t quite crossed the threshold of multi-function. Second, the changing demographic of the workforces in the industrial sector means that the traditional gatekeepers, often not versed in software or computer programming, have been loathe to adopt solutions that require a whole new skill set. The result is that the idea of programming between devices and Cloud applications is in a relative infancy. Third – and still related to the workforce demographic – creating an entire workforce of people versed in both hardware engineering and computer programming is impractical. Those factors, along with several others related to the need for network functionality and data analytics, means that a solution like Node-RED is still not completely understood, and perhaps even more pertinent, still not widely adopted by industry leaders on both the hardware and software side. But it also means that it is more necessary than ever.
Rugged Wireless Radios for International OEM Applications
For original equipment manufacturer (OEM) and military applications around the world, operational success requires reliable data delivery. This 100 percent achievable with rugged wireless radio solutions. As Industrial IoT pushes for more connectivity, coupled with the surge in commercial use of unmanned aerial systems (UAS), the pressure for around the clock command and control (C2) links is higher than ever – and it’s happening on a global scale. To support these growing needs, FreeWave has announced the general availability of the MM2-5 Watt 1.3 GHz (13X5W) integrated radio. Offered in a small package for ease of integration, the MM2-13X5W features an external 5 Watt output, making it ideal for UAS, OEM and military applications where reliability is paramount and space is at a premium. These solutions can be leveraged to deliver important data in the U.S. and abroad for a wide variety of mission critical applications. The MM2-13X5W has a lot to offer starting with it’s built in versatility and the ability to function as a gateway, endpoint, repeater or endpoint/repeater. Security is a priority – each MM2 13X5W is equipped with proprietary frequency hopping spread spectrum (FHSS) technology. It also features a line-of-sight range of up to 90 miles, and can be deployed in international settings where lifesaving communications and security are paramount. A number of these use cases include UAS applications, soldier training, environmental monitoring and other government and defense needs. Next Generation UAS Applications As the commercial drone market rapidly expands, the number of use cases is filtering into new markets. Beyond the military scope, commercial UAS applications have the potential to completely transform the monitoring, control and data analysis processes for many industries. The MM2-13X5W is equipped to support this next wave of these UAS applications, including: Pipeline monitoring as a service – drones can help maintain safe and consistent visibility of the pipeline and deliver that critical data to the network. The small form factor and proven reliability means uninterrupted data transmission in remote settings. Homeland security apps – recently, in the U.S., there have been many heated conversations around border protection. Many drone supporters believe that UAS can offer a cost effective way to monitor the nations borders. The U.S. border patrol even recently solicited contractors to build facial recognition drones. Drone delivery service – As we look at the future use of commercial UAS, drone delivery is a popular topic of conversation. We’re also seeing use cases where drones can deliver food and medicals supplies to high risk areas in third world countries. Precision Agriculture: Drones can enhance crop visibility, enabling smarter decisions and more food output. The potential impact of drones in precision agriculture is becoming recognized throughout the world. As the possibilities for commercial UAS continue to multiply, so does the need for secure C2 links for successful operations – and this is where the MM2-13X5W is an ideal solution. Additional Product Features The MM2-13x5W also features the following: 115.2 and 153.6 kbps selectable RF data rates TDMA, Super Epoch TDMA, and AES Encryption Performance tests from -40 degrees Celsius to +85 degrees Celsius Data link range up to 90 miles For more information about the MM2-13X5W, please visit: https://www.freewave.com/mm2-m13-series/
Remote Tank Level Monitoring and Automation
Industrial livestock operations have several critical needs in order to function smoothly, but perhaps most important is also the most fundamental: water. On remote sites, tank level monitoring and automation are tools that can essentially make or break the entire operation. In many of these situations, the needs of the site managers are different, so in order to maximize the technology being deployed to drive the automation process, they need to be able to customize the functionality. For operations using radio communication networks, those radios need to provide maximum programmability in order to host third party applications specific to the needs of the site managers. We recently finished a deployment that serves as an excellent case study for remote site tank monitoring deployments and included some interesting uses of radio programmability: The operator of a Rocky Mountain based livestock facility approached FreeWave to assist in remote data visualization of water tanks that are vital to its operations. The pain point was that the tank levels could only be observed visually on premise. After consideration of the terrain (mountainous, remote and big temperature swings), sensors and communications infrastructure, FreeWave engineers recommended ZumLink IPR with the Node-RED programming language for intelligent tank data visualization via browser or mobile device. The facility has minimal to zero staff most of the time. If a fault occurs such as a leak that prevents a tank from filling, the facility operators are unaware until they visually inspect the remote faulty tank, located a half mile from property headquarters. The operators wanted to reduce the number of trips to the tank facility and remotely monitor all tanks via web-based browser or mobile device.

Manufacturing in the Age of IIoT
Few industries can claim such a foundational impact on the United States as the manufacturing industry. Modern manufacturing began with the birth of the assembly line and the transformational effect it had on the automobile industry. Companies then adopted that approach to product manufacturing and logistics. The early phases of the next generation of manufacturing appeared as machine-to-machine (M2M) communication, a forbearer of the concept behind the Internet of Things (IoT). Eventually, IoT became so broad that specific designations were needed to differentiate between the consumer and industrial side of things, thus paving the way for the Industrial IoT (IIoT). Today, manufacturing companies, while often on the leading edge of automation technology, are still scrambling to adapt to the explosion of sensors, communication platforms, big data and high-speed analytics to maximize efficiency and future-proof their products or designs. Some companies are touting the idea of retrofitting – a concept that has existed for some time – but some plant engineers may be wary of the need for continual updating to a system that is bound to become irrelevant at some point. Still, the process can be relatively painless, and is quickly becoming necessary, as Plant Magazine notes: … Most food manufacturing and processing plants have motors powering essential equipment such as mixers, conveyors and packaging machines. But they’re just motors. They don’t play in the same league as other intelligent devices. With years of service to go, it’s difficult for plant managers to justify replacing motors that work just to make an upgrade with smart features. But motors can connect to the IIoT without a complete overhaul. Instead of investing in new, more intelligent/smart equipment, consider investing in sensors that provide similar functionality to connected devices. Smart sensors attach to almost any standard low-voltage induction motor. Sensor technology is sophisticated enough to be small, functional and energy efficient. For certain kinds of manufacturing plants, a complete overhaul may not be necessary, and a ‘simple’ retrofitting process might easily solve the first part of the problem. The second part of the problem, or challenge, is that along with smart hardware, plants also need the software and data processing capabilities to keep pace. Some plant engineers are solving these challenges by deploying programmable radios capable of hosting third-party applications so that the data can be transmitted in smaller, highly specific packets, making the transport both fast and easier to push into predictive analytics platforms. From there, software companies are building in the ability to process data in the cloud, essentially running all critical data and software operations through either a fog or cloud computing process. Cloud software services have the potential to be highly customizable based on the needs of the manufacturing plant. These technologies are good examples of the ongoing convergence between traditional information technology (IT) and operations technology (OT) needs in industrial markets. Currently, the manufacturing industry is sitting in an interesting spot: leaders in the M2M world, but still adapting to the IoT world. Where the industry ends up in the next 10 years could be a strong indicator of the economic and financial temperature of the domestic and international marketplaces.
7 Tips for OEMs to Improve SCADA Networking Communications
From remote field sensors to Supervisory Control and Data Acquisition (SCADA) and I/O modules, industrial wireless radios connect your device and sensor ecosystems with robust and reliable links. Furthermore, wireless data radio networking technology connected to I/O modules for SCADA applications have become faster, smarter and their firmware now easier to upgrade. More options and frequencies, including 2.4 GHz for short range I/O and 900MHz for long range data networking, continue to improve SCADA-based network communications for robotics, industrial automation, unmanned systems and heavy machinery. So what do Original Equipment Manufacturers (OEMs) need to know when deciding upon which technology to use? Below are seven tips for OEMs to consider when reviewing industrial wireless communication options. 1) Assess Technology Options for the SCADA Network Start first by identifying your needs, goals, and limitations. When it’s time to research technology options, observe what’s available today and what’s going to be available in the future, heeding the “buyer beware” saying. Communication products vary in many ways, and each manufacturer and/or technology has advantages and disadvantages. No single product—and likely not a single manufacturer—can meet all application needs. 2) Reduce Costs While some companies seek to continue to preserve existing investments of wired and wireless technologies, wireless options have clear advantages for SCADA systems. Most obviously, wireless installations reduce labor and material costs by avoiding hard-wiring remote assets. Speed of deployment adds savings. Wired systems can take days or weeks to be properly installed. Wireless networks generally require only the end points to be installed, saving substantial time and costs. Networks need to scale gracefully as the number of end points increases. After installation savings, scalability is the biggest advantage of wireless over hard-wiring, including slow integration into wired systems as it’s implemented. 3) Consider Hybrid Benefits Toss out any old perceptions. If you need mobile SCADA network access, find somebody that offers it. If you have a microwave tower place, use it. Piggyback slower licensed radio networks with faster 902-928 MHz frequency hopping, AES encrypted networks. Know that you can install I/O capable radios (analog and digital signal, 4 to 20 and 1 to 5) to relay contact closures or other data without adding a new Progammable Logic Controllder (PLC) or Remote Terminal Unit (RTU). 4) Maximize SCADA System Value With telemetry technologies, such as spread spectrum radios, the same radio used in RTUs can act as a slave device sending data back to the SCADA host, and as a repeater to other field devices or other RTUs. This allows almost limitless network expansion by using remote sites as a series of repeaters, and by using radios in the RTUs to poll the instrumentation. Polling the instrumentation creates a second network reporting wirelessly back to the RTU. This shorthaul network is the equivalent of a local area network (LAN). 5) Don’t Use a Proprietary SCADA System By using a non-proprietary SCADA system, users gain real-time access, control, and monitoring of their network (including all the devices and functions of their network). They can manage requirements of an ever-growing system allowing them to manage their network in real-time with fewer bodies and hours invested. Security and safety improves with better monitoring. For instance, some industrial systems don’t contain a process for monitoring the cathodic integrity for corrosion (like in water/wastewater and oil and gas) to avoid disaster. But with deployment of a wireless system, they can. They can begin by monitoring simple things, such as pump stations at wells, using I/O radios communicating back to the central SCADA system to get up-to-date information on the tanks’ or pipelines’ status. End users can more quickly resolve an emergency wirelessly, instead of manually. 6) Seek SCADA System Flexibility Advanced flexibility of radio communications offers benefits to new SCADA system deployments and upgrades performance of existing SCADA systems. For example, in water/wastewater industrial applications, there need to be generation/distribution, lift stations, system monitoring, and treatment facility systems in place (or planned) to meet the expanding growth of a community’s population and/or service areas to meet future requirements. Each year, many industries deploy more frequency hopping spread spectrum (FHSS) SCADA solutions to help monitor and manage critical infrastructure. Several manufacturers (including FreeWave Technologies) offer FHSS radios capable of retrieving data from remote locations. And although wireless IO (input/output) has been available, only recently have both capabilities been offered in one communication solution. 7) Seek Easy-to-Use SCADA Software OEMs implementing and using a SCADA network systems for data communications want a simplified, rapid setup and easy management of a network. That includes ability to manage multiple frequencies and multiple networks within one system. A centralized storage and management center provides easy access to system configuration and diagnostics data. Technicians in remote or harsh weather environments need robust reporting capabilities. Software like FreeWave’s ToolSuite can manage data communication diagnostics and configuration.
Connected Oil Fields in Peru
China National Petroleum Corporation (CNPC) is one of the largest energy companies in the world with operations in 28 countries. In May 2017, CNPC announced it would invest $2 billion in an oil and natural gas block in the southern part of Peru. Beyond the recent investment, CNPC has had a presence in Peru for more than 20 years, including oil fields in the northern portion of the country. To optimize operations in 2009, CNPC ran a pilot test in Piura, Peru to find the ideal communication solution for monitoring, collecting and transporting data. Piura is a coastal city located near the equator where the average temperatures hover around 95 degrees Fahrenheight. To connect the oil fields into the Supervisory Control and Data Acquisition (SCADA) system, CNPC needed a communication technology built to withstand harsh weather, such as high temperatures, large amounts of rain, wind and a variety of other environmental factors. The goal of the pilot was to have several test sites reporting to a gateway and then into a SCADA system to monitor several pumping devices and equipment including: Pump of Controller (POC), Pump Cavity Progressive (PCP), Balance Oil Recovery System (BORS) and plunger lift. FHSS for Oil and Gas In the Piura test case, the distances between links weren’t long, but depressions, canyons and steams made line-of-site (LOS) a challenge. CNPC, who tested multiple Machine-to-Machine (M2M) communication solutions in Piura, found that FreeWave’s Frequency Hopping Spread Spectrum (FHSS) technology solutions offered the most reliable connectivity in comparison to other solutions used during the test. FreeWave solutions also use repeaters that helped establish and maintain connectivity despite the lack of LOS. Additionally, the links were established easily and fast in comparison to other solutions that were a part of the test. During the entire three-month pilot, the FHSS-based M2M solutions did not lose communication or the ability to send data to the SCADA system. Industrially hardened, ruggedized FHSS technology has proven to be reliable in in many oil and gas installations around the world. As the Industrial IoT (IIoT) drives connectivity, we continue to see the demand for reliable communication links in environments like Piura that can have challenging conditions. FHSS technology offers not only a reliable, easy to install communication link, but it easily integrates into today’s modern IIoT networks.

Do You Have Intelligence at the Edge?
Smart devices have added a level of convenience to our lives that we couldn’t have imagined 20 or 30 years ago. Through applications we can manage our bank accounts, check email, listen to music, read the news, pay our bills — and that’s just the tipping point of what’s available today. Now, imagine a business being able to intelligently control the devices at the outermost edge of its communication network through third party applications that operate in a similar fashion to those used on our smartphones. With the Industrial Internet of Things (IIoT) emerging across markets, it is clear that we are heading toward a common goal of complete connectivity across a network – from Sensor-2-Server (S2S). The ability to collect data from any point in the network and transport it where it needs to go creates an opportunity for operational efficiencies driven by advanced data collection and analytics capabilities. Now, with the use of third party applications, it becomes easier to tie components together at the edge of the network and create actionable intelligence.

The Glue that Holds Our “Connected” Dreams Together
Image courtesy of Flickr Creative Commons The visage of our “smart” or “connected” destiny is often presented to us in broad strokes: self-driving vehicles, connected homes, logistics, wearables – the list continues on with each piece of evolving and maturing technology. Smart cities have a bright future, and the application possibilities seem expansive, but often lost in the conversation is the technology that actually enables the connected world. Within a smart city – or even at a micro level – within one specific industry deploying smart technology, are a wide range of considerations: how much data are we transporting? How will we transport that data? How can we make our system intelligent? Where do we need to install these intelligence-driving platforms? How can we connect our data, operational technology and information technology to the necessary access points? Who/what has access to this data and control over these machines? These are only a few of the considerations that companies must address that are responsible for the industrial services driving cities and municipalities. While security is indeed a critical piece of this landscape, before any kind of connected or smart city can be achieved, the literal communication platform upon which that connectivity is deployed must first be implemented in a way that is not only compatible with current technology, but that will also be compatible with future technologies as well. From our perspective, there are five critical elements behind a smart city connected infrastructure: Robust Cloud Services Infrastructure designed to support all consumers of smart city deliverables Core Network Architecture that can rapidly expand in bandwidth and reach Extended Access Layer network architecture that incorporates a wide range of wired and wireless technologies to reach every sensor and device or that needs to connect to the smart city infrastructure A wide range of reporting devices such as sensors, visibility devices and other end points that create the data that makes a smart city work Distributed intelligence technology that allows for local execution of applications at the access layer plus global communication of data/analytics and information While each one of these tools is important in its own right, there is a common, underlying thread that connects them: each facet depends on a robust, reliable and secure communication platform. For smart cities, these communication platforms must be capable of enabling multiple methods of connectivity, but most importantly, they must be able to provide industrial-strength Wi-Fi. Wireless connectivity is the backbone of communication between the sensors that power all facets of the connected industrial infrastructure and the big data transport that is critical to the analytics that power “smart” enterprise. Not all industrial Wi-Fi platforms are created equal, and one of the major questions facing the ongoing development of smart infrastructure centers on how to ensure that these networks are secure and compatible across multiple, and sometimes proprietary, technologies. This certainly opens up a veritable can of worms, including the idea of standardization, but without the driving force of reliable and robust communication technology, most smart city dreams will remain just that – a dream.
