One of the primary appeals of the Industrial Internet of Things (IIoT) is the promise that existing data-rich devices can be connected for greater data analysis and insight. To date, however, this promise of integration has not been so easy to achieve. Instead it has often led to IIoT systems composed of multiple software technologies, communications protocols, legacy controllers and I/O, and a variety of gateways.
“These kinds of IIoT solutions are expensive to build, difficult to troubleshoot, require multi-domain expertise and are unsustainable over the long term,” says Benson Hougland, Opto 22 vice president of marketing and product strategy. “That’s why we’ve developed the groov EPIC (edge programmable industrial controller) system to help solve these problems by combining I/O, control, data processing and visualization into one secure, maintainable, edge-of-network industrial system. groov EPIC lets engineers and developers focus on delivering value, not on triaging loosely connected components.”
By combining what Opto 22 calls “reimagined, intelligent I/O” with an embedded Linux real-time controller, gateway functions and an integrated display in one device platform, groov EPIC enables the connection of legacy systems, and control of processes and machine automation, as well as enabling subscription to web services and creation of mashups. It also provides the ability to acquire, publish and visualize data wherever it is needed—in business systems and to mobilize operators. Opto 22 notes that groov EPIC also helps simplify commissioning and wiring for rapid development and deployment.
“The groov EPIC system incorporates in one unit everything needed to connect and control field and operational devices and data, through on-premises IT databases, spreadsheets and other software-to-cloud storage and services—and back again,” says Mark Engman, Opto 22 CEO. “The ability to easily exchange data and use it where needed opens opportunities automation engineers have not had until now.”
Opto 22 expects the groov EPIC system to be of particular interest to engineers in charge of process control, machine control, manufacturing, SCADA/RTU and Industrial Internet of Things (IIoT) applications, as well as to OEMs. Hougland says that OEMs will be interested in groov EPIC's optional access to the Linux operating system through secure shell (SSH). "This access, along with toolchains and interpreters for Java, C/C++, Python, JavaScript/Node.js, and more allows OEM developers to execute their own custom developed applications on this ruggedized, edge processing control system," he says.
groov EPIC system hardware features include:

“We are a company of engineers and innovators inspired and driven to create products that unleash our customers’ imaginations,” adds Engman. “groov EPIC is a culmination of that mission, a response to user requests to integrate IT and OT technologies, simplify development and deployment, and provide a platform for long-term growth now and well into the future.”
