Opto 22 enhances groov® Industrial Edge Appliance with OPC-UA drivers for Allen-Bradley® and Siemens® PLCs, plus MQTT
New additions position groov as a complete edge appliance for industrial automation and Internet of Things applications
Temecula, CA - October 24, 2017 – Industrial automation manufacturer and Industrial Internet of Things tools developer Opto 22 today announced a new version of groov, embedding key IIoT technologies MQTT and OPC-UA drivers directly into its industrial edge appliance. Added to the groov View software for web and mobile visualization, and the open-source Node-RED development environment, the new release offers engineers, technicians, and developers a comprehensive set of tools for edge deployment in industrial environments.
These new embedded capabilities are made possible through forging close partnerships with technology providers Inductive Automation® and Cirrus Link Solutions®, and are part of the Ignition Edge Onboard™ program.
A typical use case for the new groov edge appliance is gathering data from plant floor devices or from remote plants. A customer places groov near a machine or process, uses the built-in drivers to connect to existing control systems, analyzes the data, and publishes the results back to a central server or broker on premises or in the cloud. Applications like Ignition Enterprise or any MQTT/Sparkplug-compliant software can subscribe to the data.
This scenario eliminates complex networking architectures like VPNs, firewall configurations, and remote desktop software, because all communications to the broker use a secure outbound connection from control systems, whether publishing data or subscribing to it. Additionally, because groov is a complete computing appliance, a PC is not required.
Other use cases for groov:
• A controls technician who needs to see Allen-Bradley CompactLogix™ variables on her smartphone for access from anywhere she is located
• An OEM machine builder whose machine must periodically send operational data to a central location for predictive analysis and machine learning
• A SCADA engineer who needs to efficiently control and acquire data from a large number of geographically dispersed locations over a cellular or other bandwidth-constrained network
• A facilities engineer who needs energy use and HVAC status data transmitted to a cloud database for historical logging
Ignition Edge in the groov appliance includes both a built-in OPC UA server and MQTT module. The built-in OPC UA server includes drivers to popular PLC brands, including Rockwell Automation® Allen-Bradley PLCs, Siemens S7 PLCs, and Modbus® TCP devices. Other drivers are available at additional cost. Embedding these drivers and OPC UA at the edge eliminates the cost and complexity of commissioning and maintaining a Microsoft® Windows®-based computer for translating PLC and device data to OPC UA, the only method available until now. MQTT is a bi-directional, lightweight event- and message-oriented transport protocol with a publish/subscribe architecture. This architecture decouples devices from applications, allowing users to reduce reliance on traditional IT networking resources. MQTT’s pub/sub architecture also reduces network traffic, because data is published and sent only when it changes. Supported over the MQTT transport is Sparkplug, a freely available, MQTT-based payload definition for industrial applications, which greatly simplifies implementation by defining topic namespaces and payload, and managing the state of devices in the field.
