DESCRIPTION

Opto 22’s groov RIO—remote Ethernet I/O for industrial internet of things (IIoT) and automation applications—solves two main problems with most remote I/O today:

First, specifying all the required components (rack, power supply, bus coupler, module types, and more) is time-consuming, difficult, and requires significant domain expertise.

Second, communicating data among field devices, control systems, company software, and cloud services is complex and costly, requiring PLCs, programming, and middleware.

groov RIO revolutionizes remote I/O by solving both problems.

One part number. A single part number includes built-in multifunction, multi-signal I/O; an I/O processor; power over Ethernet; and mounting without the need for a rack or chassis— in a compact industrial package.

Built-in processing and communication. Web-based configuration, flow logic software, efficient data communication methods, and multiple operations technology (OT) and information technology (IT) protocols simplify any IIoT or automation application.

groov RIO is Edge I/O

GRV-R7-MM1001-10

With groov RIO, you can:

Place the unit almost anywhere for remote I/O and data communications. groov RIO operates through a wide range of operating temperatures (-20 to 70 °C), is UL/cUL listed, and complies with the ATEX, Low Voltage, and EMC CE directives.

Supply power to groov RIO and field I/O through the ETH1 network interface, using Power over Ethernet (802.3af PoE Class 0) connections. Or use the power supply terminals to connect to a 10-32 V DC power supply.

Connect the two switched Gigabit Ethernet network interfaces in a daisy-chain configuration or in a standard star configuration. Both interfaces use a single IP address.

Connect additional devices like a Wi-Fi adapter, a USB memory stick (up to 32 GB), or a USB-to-serial adapter via the groov RIO’s USB host port (additional devices are user supplied).

Simplify field connections using the 26-pin removable field I/O termination connector with spring clamp wire retention.

Easily see the status of power, network, and I/O activity on the unit’s LEDs.

Use embedded software to quickly set up data communications between field devices and on-premises or cloud-based systems and software.

These features make groov RIO a new kind of I/O product—edge I/O. It does not require a PLC, PAC, or industrial PC, but is designed as an intelligent, distributed I/O device to meet the needs of IIoT projects, especially those that require data acquisition or communications.

Up and Running Faster

groov RIO’s single part number gives you everything you need for edge I/O, plus options. With Power over Ethernet, you can avoid the extra time and expense of routing power or adding a power supply dedicated to groov RIO. Just run a Category 5e or 6 Ethernet cable from a PoE-supplying network switch to ETH1—bringing power and networking over a single cable. PoE can also power field I/O (for details, see "Specifications" on page 8).

After you power up your groov RIO unit, open a web browser on a computer or mobile device to connect to your RIO's IP address or hostname. groov Manage—a web app that gives you command center-like access to your groov RIO—opens so you can configure, troubleshoot, and commission built-in I/O, networking, and security.

groov RIO as Edge I/O

Configure a Mix of Channels

The first product in the groov RIO family is the GRV-R7-MM1001-10, a 10-channel, multi-signal, multifunction edge I/O unit with over 61,260 unique field I/O combinations. (How is this possible? Take a look at the wiring diagram on page 16 to see all the available functions and input/output configurations. To understand how we calculated these combinations, visit info.opto22.com/61260.)

Through groov Manage, you select a channel, configure its I/O signal, select any function supported by the selected channel—such as counting, latching, clamping, and more—and then save your configuration. groov RIO begins converting signals into data that a computer can understand as soon as field devices begin transmitting signals.

groov RIO acts as edge I/O to exchange data between OT field devices (at bottom) and IT computers and software (at top).

Send Data Wherever You Like

Once the groov RIO unit is configured, continue to use groov Manage to directly send data wherever you need it, without requiring a PLC or middleware.

Configure and enable MQTT on RIO to securely send data—as Sparkplug-B or string payloads—to MQTT brokers on premises or in the cloud.

Create a data flow with the built-in Node-RED editor and runtime to send data to cloud services, databases, other I/O channels, and APIs through pre-built nodes.

Develop simple user interfaces (UIs) with Node-RED UI nodes and serve them directly from RIO to any mobile or web-based device.

Security

groov RIO provides several features to help keep your data secure.

User account management—groov RIO has no default username or password. You must set up a first Admin user account and remember its username and password, as these user credentials are secure and cannot be recovered. You can also create more users and set their passwords and permissions.

VPN client—You can securely connect to groov RIO using a VPN. Support is provided for OpenVPN servers.

Configurable firewall—Configure the device (or host) firewall in groov RIO for greater security. You can control which ports, protocols, and interfaces are open for incoming connections to the services listening on each port number. For example, you should disable the ports of unused protocols.

groov RIO in an Opto 22 Control Program

In addition to its use as autonomous edge I/O, groov RIO can also be used to expand the scope of existing control programs or industrial applications. You can add groov RIO units to monitor, control, and collect data from field devices:

In a PAC Control™ strategy—With PAC Project™ Basic or Professional Software Suite, add a groov RIO as an I/O unit, configure your I/O points, then download your strategy to a:

– groov EPIC

– SNAP PAC controller or SoftPAC running PAC Controller

firmware 10.3 (also requires PAC Project 10.3).

In a CODESYS® application—Download and install the Opto 22 Library Package for CODESYS Development System, version

2.0.0.0. Update your application and you’ll be ready to add a groov RIO and configure I/O points.

In a custom control program—You can access groov RIO I/O programmatically through OptoMMP or REST APIs.

processor running firmware version 2.0.0

Leverage Existing groov and SNAP PAC Knowledge

If you already have groov EPIC, a groov Box™, or SNAP PAC control systems, you can expand your I/O footprint with the addition of groov RIO units. groov RIO works as remote I/O with groov EPIC and SNAP PACs, and it uses many of the same principles and technologies found in your existing groov or SNAP PAC control system:

groov Manage for I/O configuration and other tools to help manage your groov RIO

MQTT to transmit Sparkplug or string payloads Node-RED for simple data flows OpenVPN client to connect to an OpenVPN server running a

virtual private network PAC Control for programming and I/O configuration Distributed control—I/O features like counting, latching,

totalization, and minimum & maximum values continue to run independently on the RIO unit, even if communication to the controller is lost.

PID Loop Control

A groov RIO unit can independently solve PID loops when any analog output is configured as the Control Output (CO) of the loop. PAC Control is required to configure the PID loop function. Up to four independent loops are supported, with configurable loop times.

More Ways To Exchange Data

groov RIO supports both OT and IT protocols and tools, making it easier to safely move data among field devices and computer networks. Choose the method that works best for you:

Modbus TCP/IP master—groov RIO is a Modbus TCP slave out of the box. Use your favorite Modbus TCP master device or software to poll RIO's I/O channels. A Modbus TCP calculator is built into RIO's groov Manage application, helping you quickly find the Modbus Unit ID and register for a memory map area.

C++ or .NET and free SDKs—With your favorite development tool and our free SDKs, you can programmatically access I/O values on a groov RIO by accessing the OptoMMP memory map locations of each channel. An OptoMMP calculator is built into RIO's groov Manage, making it simple to identify the MMP addresses of I/O channels and their features.

HTTP/S, JSON, and REST APIs—The developer community has embraced REST APIs as a method of accessing I/O with HTTP/S and JSON. Opto 22 provides REST APIs for groov Manage, which you use to access the I/O values on a RIO unit. A Swagger API document is built into RIO to quickly access REST API calls and evaluate responses.

internet of things (IIoT) applications. groov RIO has support for MQTT built in, requiring only a simple configuration to publish I/O data and subscribe to commands as Sparkplug-B or string payloads.

We know the idea of contemplating over 61,260 unique field I/O combinations is a bit much, so we created an online app to help you select the right combination and correctly wire your field devices to your groov RIO: The groov RIO Explorer.

With this web app, you can select which function you want on each channel, and then the app displays the corresponding wiring diagram. You can print out the wiring diagram or save it as an image for reference.

Reset Switch

This switch resets your groov RIO to factory defaults, erasing all the changes you made to your RIO device and setting the firmware to the version installed when it was shipped.

Discrete Channel Indicators

There are two columns of indicators on the face of RIO:

For discrete input channels, the column on the left indicates state. For discrete output channels, the column on the right indicates

state.

When a channel is configured for discrete input or output, its corresponding indicator lights up when the channel is on.

Terminal Connector

The terminal connector provides a spring-clamp wiring system to securely connect the wires from your field devices to RIO. To learn how to use a spring-clamp wiring system, see "Pinout and Wiring" on

page 15.

The terminal connector for GRV-R7-MM1001-10 is gray in color to differentiate it from groov I/O module terminal connectors, which have the same footprint as RIO. The difference in color helps you remember that this terminal connector is designed for the GRV-R7-MM1001-10 to accurately read thermocouple inputs.

Power Supply Connector

To supply power with an external power supply, Opto 22 recommends you follow these wiring guidelines:

Use a 10 to 32 V DC power source or supply. Use wire size 16 to 12 AWG. Keep the wires as short as possible.

Power Wiring Diagram

Before wiring the groov RIO to an external power supply, verify that your wiring cables conform to the requirements described previously.

Network Ports

The Ethernet ports are switched, which means you can network them in a daisy-chain configuration or in a standard star configuration using either Ethernet port. Both ports use the same IP address.

ETH1

The network ports support speeds of up to 1 Gbps. Check the category of your Ethernet cable to ensure you achieve the speeds you expect from your network.

The ETH1 port, when connected to Power Sourcing Equipment (PSE)—for example, a PoE switch—through a PoE-rated Ethernet cable, can power RIO. This eliminates the need for a separate external power supply. Opto 22 recommends you select a PSE that supports IEEE 802.3af and has sufficient power available for all the powered devices (PDs) connected to it.

USB Host Port

The USB host port can extend the capabilities of the groov RIO. You can connect a:

WiFi adapter to add wireless connectivity. USB-to-serial adapter to read and write data to serial devices. USB memory stick to expand the storage space; for example, to

increase data logging capacity.

The wireless interface WLAN0 (which becomes available when you plug in a WiFi adapter) does not provide access to other RIOs in a daisy-chain configuration because this interface has a separate IP address on a separate subnet.

Wireless Connectivity

The following WiFi USB adapters have been tested and proven to be compatible with groov RIO:
