DESCRIPTION
The Edge Programmable Industrial Controller is an embedded Linux®,
real-time controller with gateway functions.
The modern design of the groov EPIC processor offers a compact,
industrial computer that features a resistive-touch, high-resolution
LCD display. The LCD display lifts to provide easy access to the power
button, power supply connectors, network interfaces, ports, and
status LEDs.
Dual, independent Gigabit Ethernet network interfaces securely
segment trusted networks (like your control network) from
untrusted networks (like the Internet).
Dual USB ports for serial interfaces, WiFi adapters, and keyboard,
mouse, and touchscreen controls.
HDMI port connects to an external monitor for displaying
configuration and groov View HMI on an external large screen,
which is also useful for OEM applications where the EPIC system is
built into a machine.
The processor can operate through a wide range of operating
temperatures (-20 to 70 °C) and with its industrial design, it can be
used in a large variety of applications and operating environments.
The CPU is an industrial, quad-core ARM® processor running opensource Linux with real-time extensions.

CODESYS Runtime Engine for running IEC 61131-3 compliant
programs created with the CODESYS Development Environment.
All IEC 61131-3 languages are supported, including Function
Block Diagram (FBD), Structured Text (ST), Sequential Function
Charts (SFC), and Ladder Diagram (LD). (Requires the free
CODESYS Runtime Engine License, GROOV-LIC-CRE.)
You can run complex control programs on the groov EPIC processor
developed with:
PAC Control, a flowchart-based programming language
CODESYS Development System V3, an IEC 61131-3- compliant
programming language
Python, C/C++, JavaScript, and other popular software
development tools (requires free SSH License, GROOV-LIC-SHELL)
The groov Manage app gives you central command-like access to your
groov EPIC system, helping you configure, troubleshoot, and
commission your system. The consistency in interface design
between the groov Manage app running on the groov EPIC processor
and the groov Manage app running on your computer, smartphone,
or tablet ensures a seamless experience between devices. You don’t
have to remember to do something different for each device to
achieve the same result.
groov View offers easy browser-based, mobile-ready development of
a custom HMI with trending, events, and user notification.
Communication is secured with user authentication and TLS
encryption. And, because the HMI is web server-based, what you
build can be viewed on any authorized device with a web browser.
OptoSupport Remote Support Service (RSS)
Support has never been closer! With OptoSupport RSS, you can create
a secure, encrypted connection between your groov EPIC controller
and Opto 22's support team so they can remotely help diagnose and
troubleshoot any issues. The remote connection can only be started
by you, and only after you and an Opto 22 support team member
have determined that the best way to help you is through a remote
connection.
programs, or custom developed applications with popular
software development tools.
Connectivity and Data handling. Acquire, move, and share
data from industrial systems, legacy equipment, business and IT
systems, and the cloud through a variety of connecting
technologies like Node-RED, REST API, Ignition SCADA,
OptoDataLink, and OptoOPCServer.
Visualization. Securely monitor, control, and use data as you
need it—locally, on premises, or from anywhere using groov View.
Authorized users can view your operator interface on the groov
EPIC processor, a mobile device, a computer, or anything with a
web browser.
The groov EPIC system builds on decades of field-proven design and
modern open standards to give you reliable industrial automation
plus a full internet of things (IoT) suite of tools and technologies,
built in.
The system includes processor, software, I/O modules, chassis, and
power supply.
The chassis holds the power supply, processor, and selected, modular
I/O modules you need for your application. For more information, see
the groov EPIC Chassis Data Sheet (form 2247).
Power supplies are available for AC power, DC conversion, and passthrough connections from a DC power supply you already own. For
more information, see the groov EPIC Power Supplies Data Sheet
(form 2246).
The groov I/O modules connect a variety of field devices to your
groov EPIC system. The table on the following page lists the available
I/O modules and the form numbers to learn more about them.
The groov EPIC system
The GRV-EPIC-PR1 is part of the groov EPIC system, which provides a

STATUS
Indicates link speed (Off = 10 Mbps,
Green = 100 Mbps, Orange = 1000 Mbps)
Indicates link status or activity
(on/solid = link present, blinking = link present and local activity)
Indicates status of power (Green = on;
Red = on, resetting)
Indicates whether the unit is running with full
functionality. (Green = all normal; blink green
and red = starting a restore to defaults)
Independent Ethernet network interfaces
The Ethernet network interfaces are independent, which means they
are not connected internally. Each requires its own IP address, and the
two interfaces must be on different subnets.

More about Opto 22
PRODUCTS
Opto 22 develops and manufactures reliable, easy-to-use, open
standards-based hardware and software products. Industrial
automation, process control, building automation, industrial
refrigeration, remote monitoring, data acquisition, and industrial
internet of things (IIoT) applications worldwide all rely on Opto 22.
groov EPIC® System
Opto 22’s groov Edge Programmable
Industrial Controller (EPIC) system gives
you an industrially hardened system with
guaranteed-for-life I/O, a flexible Linux®based processor with gateway functions,
and software for your automation and IIoT
applications.
groov EPIC I/O
groov I/O connects locally to sensors and
equipment with up to 24 channels on each I/O module. Modules
have a spring-clamp terminal strip, integrated wireway, swing-away
cover, and LEDs indicating module health and discrete channel status.
groov I/O is hot swappable, UL Hazardous Locations approved, and
ATEX compliant.
groov EPIC Processor
The heart of the system is the groov EPIC processor. It handles a wide
range of digital, analog, and serial functions for data collection,
remote monitoring, process control, and discrete and hybrid
manufacturing.
In addition, the EPIC provides secure data communications among
physical assets, control systems, software applications, and online
services, both on premises and in the cloud.
Configuring and troubleshooting I/O and networking is easier with
the EPIC’s integrated high-resolution color touchscreen. Authorized
users can manage the system locally on the touchscreen or on a
monitor connected via the HDMI or USB ports.
groov RIO
groov RIO revolutionizes remote I/O by offering a single, compact,
PoE-powered industrial package with web-based configuration,
commissioning, and flow logic software built in, plus support for
multiple OT and IT protocols.
Standing alone, it meets the needs of small, variable I/O count
applications, especially those that require
data logging or data communications,
commonly found in IIoT applications.
groov RIO can also be used with a
Modbus/TCP master or as remote I/O for
a groov EPIC system.
Older products
From solid state relays (our first products)
to world-famous G4 and SNAP I/O, to
SNAP PAC controllers, older Opto 22
products are still supported and still
doing the job at thousands of installations worldwide. You can count
on us to give you the reliability and service you expect, now and in the
future.
QUALITY
Founded in 1974, Opto 22 has established a worldwide reputation for
high-quality products. All are made in the U.S.A. at our manufacturing
facility in Temecula, California.
Because we test each product twice before it leaves our factory rather
than testing a sample of each batch, we can afford to guarantee most
solid-state relays and optically isolated I/O modules for life.
groov EPIC Software
Software included in the groov EPIC processor:
PAC Control engine to run PAC Control and PAC Display
CODESYS Runtime engine to run IEC61131-3 compliant programs
built with CODESYS Development System
Optional access to the Linux operating system through a secure
shell (SSH) to download and run custom applications
groov View for building your own device-independent HMI,
viewable on the touchscreen, PCs, and mobile devices
Node-RED for creating simple logic flows from pre-built nodes
Ignition Edge® from Inductive Automation®, with OPC-UA drivers
to Allen-Bradley®, Siemens®, and other control systems, and MQTT
communications with Sparkplug for efficient IIoT data transfer
