Making the switch: SNAP PAC to groov EPIC

New technical note helps current SNAP PAC users decide if, when, and how to migrate to the new groov EPIC system.

movingOpto 22 customers have been relying on the SNAP PAC system for their controls and automation applications for over 10 years. But now you keep hearing about the new technology of the groov EPIC system. How is it different? Should you make the switch? What would be the benefits of upgrading, and what issues would arise from making the change?

These are typical questions asked of our pre-sales engineering team, so we've put together a technical note that provides some detailed explanations: Migrating from SNAP PAC to groov EPIC.

The groov EPIC (Edge Programmable Industrial Controller) can add a range of new capabilities to your existing SNAP PAC system so that collecting, processing, displaying and exchanging data becomes much easier. The tech note covers the different migration paths available:

  • Adding an EPIC as your primary controller and keeping existing SNAP PAC I/O units as remote I/O
  • Using the EPIC as remote I/O within a SNAP PAC system
  • Adopting the EPIC for its many capabilities but not using it for I/O

The technical note also explains the specification differences between SNAP I/O and groov I/O. And you'll get an overview of features in the available HMIs: groov View vs. PAC Display.

Before deciding about migrating to groov EPIC, you'll want to spend some time reviewing the comparison chart (page 5) to see the similarities and differences in your current controller and a groov EPIC processor.

Remember we're always here to help you decide and to make the transition as simple as possible. Contact our pre-sales engineering team for any additional questions or concerns you might have.


Keep calm and groov on!
