History of the InternetVIDEO ON THE TOPIC: Small Office Networking - Intro (series part 1)
The IIoT provides many benefits to machine builders and their customers, but new solutions are needed to reduce complexity and expense while maintaining a high level of security. Like many OEM machine and equipment builders, a California-based oven manufacturer needed to implement an industrial internet of things IIoT solution to meet customer demands, improve remote monitoring, and remain competitive in the marketplace.
The OEM builds ovens used in a variety of industrial and commercial applications, and it wants to differentiate its ovens from those of its competitors to increase sales.
Feedback from customers points to three ways to improve upon its established offerings: —Make it easier for customers to integrate the oven with the other process control systems in their plants —Add human-machine interface HMI options so customers can more easily monitor and control oven operation —Reduce customer costs, especially for operation and maintenance.
Initial investigation showed that achieving these goals promised to be difficult due to a number of challenges. One method was to develop drivers for intersystem communications, but because the process control systems already in service are proprietary, a custom driver would have to be developed separately for each.
This approach would also present future maintenance issues because many different versions of custom driver software would have to be supported, with each version requiring review and possible updates to keep up with changes to the corresponding process control system. Integration with existing HMIs would run up against the same problem. These ideas sounded possible but expensive to develop and maintain.
Reducing customer costs seemed even more difficult. If they could get operational data from ovens installed at their customer locations, they could analyze the information to improve oven efficiency. These data could also be used to reduce customer costs by providing a new level of service.
For example, the OEM could track burner ignitors, anticipate failures and contact the customer in advance to avoid unplanned downtime. Scheduled maintenance would likely be reduced as well, replaced by preventive maintenance—and even predictive maintenance—to determine the likelihood of failures before they might occur. Many IIoT or data-intensive automation applications end up being far more complex with more security risks than initially anticipated.
The result is that the final cost and human resources required are more than many companies can afford. Getting data from the edge of the network—from the sensors and actuators in factories, commercial buildings and remote sites—to the databases and people who need to use that data can be daunting.
Bi-directional communication for control can be even tougher. As soon as data moves outside the immediate network or off premises—for use in the company computer network, remote locations or on a tablet or smartphone connected to the internet—middleware requirements increase and security concerns balloon. A typical architecture to enable these communications requires many components and significant configuration and programming Figure 1. Caption: Traditional methods of exchanging data between field devices and cloud-based or on-premises applications require many components and steps.
Addressing challenges and issues Control system engineers are familiar with programmable logic controllers PLCs and programmable automation controllers PACs. Both have been used and improved over many years, incorporating capabilities formerly found only in proprietary SCADA systems, adding communications with Microsoft Windows-based HMIs, running on standard Ethernet networks and so on.
But for IIoT and other challenging applications, more is often needed from automation systems. For these and future applications, a new approach is needed to simplify connections and communication—a new product that does much more than a PLC or even a PAC.
This new type of controller can be referred to as an edge programmable industrial controller EPIC. An edge programmable industrial controller can be used to replace multiple hardware and software middleware components when transferring data from the field to cloud and on-premises applications. A manufacturing line or shipping department in a factory, refrigerated rooms or barcoded containers in a warehouse, pumps and pipes and storage tanks at remote sites—all are at the edge of the network, and all have data that can be used to improve processes and increase profits.
An EPIC device installed at the edge of a network actively works on the data as well by filtering out anomalies, by labeling, by storing and by transmitting only by exception to reduce unnecessary volume, and by converting values from one protocol to another. This data preprocessing makes operations, enterprise and business cloud applications more efficient. Because it is the single source of truth for data, an EPIC device can also securely share the data with software and equipment including other control systems, building management systems, databases, cloud services and others.
An EPIC device provides programming options, some of which reflect traditional automation tools, and others that come from the PC and internet world. It instead lets users leverage what they already know to create control, data exchange and HMI programs more quickly. Industrial: Controllers often have to operate in difficult environmental locations. One problem with using PCs in industrial automation is that an off-the-shelf PC cannot be trusted to stand up to harsh environments.
In contrast, EPIC devices incorporate real-world automation experience and are built to withstand tough conditions. Industrial-grade components like solid-state drives are designed for long life. Controller: At heart, an EPIC device is a real-time industrial controller designed to run control applications. The EPIC can be wired directly to sensors and actuators in the oven to provide control, monitoring, data processing, communication and visualization in a single unit.
The first of what are anticipated to be many EPIC devices on the industrial automation market comes from Opto 22 Figure 3. Their EPIC device was released in May , and quarterly software updates since then have added significant features. Perhaps the greatest advantage of an EPIC device for the OEM, however, is the ability to get the data needed from their ovens at customer sites, without causing security issues for their customers. The broker handles all data communications.
Each data source sends data to the broker only when it changes using report by exception. Equipment and software that need data subscribe to only the data they need, and they receive it from the broker only when it changes Figure 4.
Most important from a security standpoint, all communications are initiated outbound from the data source or subscriber to the broker.
Once initiated, data can flow in both directions. Security is maintained and IT involvement is reduced. EPIC devices can provide real-time control for all kinds of traditional automation applications, and also handle IIoT and data-based tasks. These devices offer a simple, secure, maintainable and cost-effective solution for IIoT data communication by flattening the architecture required to transfer data from the field to a cloud-based or an on-premises application.

Like fiber, Free Space Optics FSO uses lasers to transmit data, but instead of enclosing the data stream in a glass fiber, it is transmitted through the air. Historically, Free Space Optics FSO or optical wireless communications was first demonstrated by Alexander Graham Bell in the late nineteenth century prior to his demonstration of the telephone! The beams of light in Free Space Optics FSO systems are transmitted by laser light focused on highly sensitive photon detector receivers. These receivers are telescopic lenses able to collect the photon stream and transmit digital data containing a mix of Internet messages, video images, radio signals or computer files. Commercially available systems offer capacities in the range of Mbps to 2.

The history of the Internet has its origin in the efforts of wide area networking that originated in several computer science laboratories in the United States , United Kingdom , and France. In the early s the NSF funded the establishment for national supercomputing centers at several universities, and provided interconnectivity in with the NSFNET project, which also created network access to the supercomputer sites in the United States from research and education organizations. Commercial Internet service providers ISPs began to emerge in the very late s. Limited private connections to parts of the Internet by officially commercial entities emerged in several American cities by late and ,  and the NSFNET was decommissioned in , removing the last restrictions on the use of the Internet to carry commercial traffic. In the s, research at CERN in Switzerland by British computer scientist Tim Berners-Lee resulted in the World Wide Web , linking hypertext documents into an information system, accessible from any node on the network.
The IoT revolution, requiring a dramatic increase in strong, secure communication links, offers providers an opportunity to not only play a larger role but to create new value. The Internet of Things IoT has become increasingly visible thanks to the rise of intelligent thermostats, interactive fitness trackers, and the promise of autonomous vehicles. Such technologies are compelling because they make the things around us smarter and more interactive. Connecting all these devices is what turns isolated pockets of technology into a network that generates and pools data in ways that lead to valuable insights. Thanks to the central role of communications in many IoT deployments, how companies create value is often a function of the interaction between sensor technology and the network layer. Linking new and legacy sensors within an IoT ecosystem often means that companies seeking to realize value from the IoT need to work closely with their communication services providers CSPs. Such collaboration is unlikely to come easily to either party. Consumers of communications services can easily overlook the challenges associated with creating the sort of connectivity required to realize the full benefit of IoT technology. Providers of network services can be expected to have their own biases to overcome. The rise of the Internet separated communications services from the communications network they ride over.
