Industrial-strength MQTT with Sparkplug B PostedWednesday, January 20,2021 at 6:16 PM Are you a system integrator, developer, engineer, or manager wondering if MQTT could help with your industrial internet of things (IIoT) application? If so, this white paper can give you some answers. It explains the fundamentals of the protocol, demonstrates how the Sparkplug B specification adapts MQTT to industrial applications, and shows you how to establish and scale MQTT networks using industrial edge computing.This approach creates a secure foundation for IIoT networks that scale up smoothly and operate reliably in support of mission-critical applications.Download: https://www.opto22.com/support/resources-tools/documents/2357-white-paper-industrial-strength-mqtt-sparkpl Read More
Building Industrial IoT from Edge to Cloud PostedWednesday, August 19,2020 at 7:02 PM Sharing process data has long been a goal of industrial automation, but traditional operational technology (OT) architectures are poor at scaling, priced prohibitively, and demand complex configuration and support. So how can we achieve the new, more ambitious goals of the industrial internet of things (IIoT)?Read this white paper to see how next-generation distributed I/O and control are opening new possibilities for connected infrastructure.

I/O for the IIoT PostedWednesday, April 22,2020 at 2:52 PM In an era of increasing connectivity and technical capabilities, it seems like simple ideas should be simple to achieve. But industrial internet of things projects, even simple ones, are still expensive, demand special skills, and involve many steps. This white paper introduces edge I/O, a new kind of product that simplifies IIoT applications. Opto 22's groov RIO is an example of an edge I/O product. Read More

Meet the Future: Edge Programmable Industrial Controllers PostedTuesday, March 26,2019 at 6:05 PM For today's controls engineers, new demands to use and share data present three main challenges: security, complexity, and expense. These IIoT or data-intensive automation applications typically require many steps and a lot of middleware: hardware, drivers, parsers, and custom software. Time-consuming to set up, difficult to maintain and change, they also open major security concerns.See how a new kind of industrial controller—an edge programmable industrial controller, or EPIC—can simplify and secure automation and IIoT projects, while reducing cost and complexity.

Edge Computing Primer PostedFriday, September 2,2016 at 1:06 PM Successful Internet of Things (IoT) applications send data from systems that monitor and control the physical world to information technology (IT) data processing systems. There the data can be analyzed and the results used to improve business capabilities: better inventory management, better predictive maintenance, reduced asset downtime, and much more.But first we need to solve 3 problems: how to connect the physical world to the IT world, how to handle the huge masses of data that physical systems produce, and how to efficiently structure the IoT.This white paper explores these problems and how edge computing can help solve them.
