Tips when using PAC Project with groov View, MQTT, Node-RED, RESTful API, and more

Are you wondering what else you can do to improve your PAC Project system’s performance? Did you optimize your SNAP PAC system and apply the same techniques to your groov EPIC system? There may be some other options you might not think of, like these:

Whether you’re running an edge device like groov EPIC or a classic SNAP PAC system, performance optimization is a balance among logic, I/O communication, and HMI responsiveness. You might find some time savers in the Optimizing PAC Project System Performance technical note.

Here are a few highlights from the tech note.

Learn how cutting-edge industrial devices using artificial intelligence (AI) are saving mining companies thousands through early leak detection.

Are you in an industry with strict regulations that require constant remote monitoring? That's what several companies are facing in Peru's mining region. 

With miles of mining pipelines in Peru, national regulations require continuous monitoring to prevent spills and ensure safe operation. For mining companies, this means the search is on for practical, cost effective, and sustainable solutions to meet these standards.

Watch recorded conference sessions for FREE and learn how to connect your systems with Node-RED.

Included in groov EPIC and groov RIO is Node-RED, an open-source software program that allows you to wire together devices, databases, cloud applications, and APIs (application programming interfaces) using simple logic flows.

Node-RED is being used in a wide range of mission-critical applications, from city utilities and semiconductor fabs to manufacturing lines and smart buildings.

Anywhere an engineer needs two systems to talk, Node-RED often shows up. It’s a visual way to move data, trigger actions, and link systems. Due to Node-RED's growing popularity, it's no surprise that last week's Node-RED conference provided some excellent resources and idea exchanges.
