MQTT: Mission-critical fault tolerance

Posted by Josh Eastburn on Jun 16, 2020 9:01:50 AM

Our MQTT series continues with a deep dive into groov EPIC’s (and now groov RIO’s) features for high-reliability MQTT networks.

At its heart, MQTT was designed for unreliable networks. Back in the ’90s, ConocoPhillips (now Phillips 66) was looking for a way to improve telemetry reporting over its low-bandwidth dial-up and costly VSAT (small satellite dish) SCADA network. IBM partnered with system integrator Arcom Control Systems (now Cirrus Link Solutions) to develop a minimalist communication protocol that could gracefully handle intermittent network outages and high latency among many distributed devices over TCP/IP.

MQTT: Faster, better with Sparkplug B

Posted by Josh Eastburn on Feb 18, 2020 3:30:40 PM

In part 2 of our series, we look at how to set up groov Manage and Ignition Edge for publishing with Sparkplug B payloads.

MQTT is the darling of enterprise IoT because of its efficiency, simplicity, and flexibility, which makes it ideal for use in applications that communicate with resource-constrained edge-of-network devices. After being nurtured for years within IBM, and incorporated into their smart energy, health, and utilities solutions, MQTT has become the chosen messaging protocol across all the major cloud IoT platforms as well as highly scalable applications, like Facebook Messenger.

New Automation 101 video explains Sparkplug for MQTT

Posted by Janice Colmer on Dec 10, 2018 11:13:46 AM

The industrial MQTT communication protocol is a powerful tool that allows you to exchange device data freely among devices and applications, with little or no IT involvement.

Its simplicity and flexibility make it a popular choice for today's IIoT applications. Adding the open-source Sparkplug specification to MQTT adds even more structure and better support for industrial applications.
