It’s not a PLC. It’s not a PAC. It’s not a PC.
It’s an Edge Programmable Industrial Controller (EPIC),
and the acronym says it all.



Now you can collect, process, view, and exchange data where it's produced—at the edge of the network. When you work with data at the edge, you don’t have to worry about latency, and you have one single
source of truth.

Securely share data among databases, cloud platforms, web services, PLC systems, and other systems
and equipment, using open, modern communication standards.

Move data efficiently, decrease network load, and reduce IT reliance by using MQTT/Sparkplug communications.

Visualize data on the controller’s integral touchscreen, an external HDMI monitor, or from any
web browser or mobile device.

Now you have new programming options:

+ Program with the field-proven, flowchart-based, multi-chart control language PAC Control.
+ Use the IEC 61131-3 compliant CODESYS Development System and CODESYS runtime.
+ Exchange data using the visual, flow-based editor and runtime Node-RED, with its free pre-built nodes for databases, web services, and more.
+ Run your own C, C++, Java, Python, or other custom-developed application on an open, Linux-based automation system, using secure shell access.

From plant floors to remote sites, the edge demands industrially hardened equipment. Now you don’t have to worry about processing power in challenging locations.

groov EPIC has:
Stainless steel processor and I/O chassis with a secure, screw-down design
+ Industrial quad-core ARM processor and solid-state drive
+ Industrial high-resolution color touchscreen display
+ UL Hazardous Locations and Class 1 Div 2 approval
+ Wide -20-70ºC temperature range
+ ATEX compliance

You can rely on real-time control and I/O from an automation manufacturer with 45+ years of experience. Opto 22’s worldwide reputation for quality was built on solid state relays and I/O, and all their experience is poured into the design of groov EPIC.

You’ll appreciate:
Integral touchscreen for local configuration, commissioning, and troubleshooting–no PC required
+ Real-time, open-source Linux operating system
+ Multi-tasking real-time control engine
+ Dual independent Gigabit Ethernet network interfaces to help securely segment your control network from your business network
+ HDMI port for optional local monitor
+ USB ports for keyboard, mouse, Wi-Fi dongle, serial connections
+ Intelligent, hot-swappable, guaranteed-for-life I/O
+ Spring-clamp field wiring up to 14 AWG, with an integrated wireway and adjustable cover
+ Multicolor LED for I/O module quality, plus channel indicators for discrete I/O
+ Integrated power supply options


 The Challenge of IIoT

Getting data from the edge of the network—from the sensors and actuators in factories, buildings, and remote sites—to the software and people who need to use it is hard. It involves:
- Complexity
- Security
- Cost
Field devices understand electrical signals, but computers and mobile devices don't. Most control systems are proprietary or specific to automation—EtherNet/IP, Modbus, Profibus, serial, OPC. But computers and mobile devices use standard Ethernet or WiFi networks and open protocols like TCP/IP, HTTP/HTTPS, JSON. It takes a chain of middleware to translate data between these systems and move it where you want it. Hardware, drivers, parsers, and custom software are costly to purchase, install, and maintain, and every link in the chain opens security concerns.

For example, here's a typical IIoT setup:

IIoT problem: too much middleware
We need a simpler way. We need an EPIC improvement—an Edge Programmable Industrial Controller.
Opto 22's groov EPIC eliminates middleware and shrinks the steps to get the data we need:
How does groov EPIC solve the challenge?

An edge programmable industrial controller, groov EPIC is much more than a PLC or a PAC.
It has been designed from the ground up as both a reliable real-time industrial controller and a processor to collect, process, display, and exchange data.
+ groov EPIC talks directly to field devices, other control systems, databases, cloud services, and a lot more.
EPIC helps solve the challenges of complexity, security, and cost.
+ One industrial unit takes the place of all that middleware. Encryption, user authentication, and communication options help you implement a
more secure system.
+ Getting data where you need it is faster and easier
with built-in, easy-to-use software.

Frequency Converters

Certain equipment cannot operate on the wrong frequency. This can cause damage or premature wear on the equipment, for example, 50 Hz designed equipment cannot operate at 60 Hz. If you force the equipment to operate outside its design criteria, there will be trouble. More often than not, the equipment will be damaged immediately. If not immediately, it will fail over time from fatigue and overheating.

With our ever growing global economy, equipment from other parts of the world are being used more frequently in countries that they were not manufactured in.

This usually results in the need of a Frequency Converter. This will change the local utility’s frequency (and sometimes its voltage) as needed. As a result, it will be compatible with the power requirements of the equipment you are trying to operate.

Soltec is a leading supplier of excellent Frequency Converters > choose 50, 60, 400 HZ in or out > both single or three phase models.

MasTec supplies to Oceania many of these Soltec frequency converters each year.

Typical applications are for converting NZ 230VAC 50 HZ power to USA 110VAC 60HZ or 230VAC 50HZ to 230 VAC 400HZ aircraft power or the other way around.

Almost all Soltec products can be ordered with an extra transformer to make the output Galvanically Isolated.

We have supplied models up to 20 KVA with these very heavy transformers. In Labs and some factory systems this is essential for stable operation of a Control system or IT system.

The large Industrial ALP UPSs are always galvanic isolated and are modular growing up to 200KV+.

  Current Transformers

Current transformers are instrument transformers. Instrument transformers scale the large values of voltage or current to small, standardized values that are easy to handle for measuring instruments and protective relays. The instrument transformers isolate measurement or protection circuits from the high voltage of the primary system.

A current transformer provides a secondary current that is accurately proportional to the current flowing in its primary. The current transformer presents a negligible load to the primary circuit.

Current transformers are the current-sensing units of the power system and are used at generating stations, electrical substations, and in industrial and commercial electric power distribution.
