AI module provides predictive analytics from control data

08 July 2019

The new FactoryTalk Analytics LogixAI module from Rockwell Automation – formerly known as Project Sherlock – uses artificial intelligence (AI) to detect production anomalies and alert workers so they can investigate or intervene, as necessary.

This add-on module for ControlLogix controllers fits directly into a control chassis and streams controller data over the backplane to build predictive models. It can continuously monitor a production operation, detecting anomalies against its derived understanding and warning operators and technicians when things change in unexpected ways. 

For example, the module can help operators spot performance deviations in equipment such as mixers that could affect product quality or lead to downtime. It can also be used as a virtual sensor. Instead of taking a reading, like the humidity of a packaged food product, the module can analyse variables from line assets like sprayers, dryers and burners to predict a measurement, virtually.

Workers can then be notified of problems by configuring alarms on a HMI or dashboard.
