Network Automation Engine

At the heart of the Metasys® system is the series network engine (SNE/SNC).  The SNE, available in nine options, enables internet connectivity and Web-based access to the Energy Management System.  It handles all of the site-level functions such as alarming, schedules, password, trending, and data storage.  Models are available to communicate via JCI N2, Lon, and BACnet/MSTP or BACnet/IP.  The user interface stays the same regardless of the model, and the onboard tools let you build the database and generate graphics.

SNC Engine examples

There are many information technology components onboard the SNE/SNC.  The operating system is the embedded version of Microsoft XP®, and the user interface uses the JAVA virtual machine.  The NAE will deliver Web services to other applications.  In fact, you'll find more IT-type vocabulary than you've ever seen before in the SNE/SNC Product Bulletin.


General Purpose Application Controllers (CGs), VAV box Controllers (CVs), Input/Output Expansion Modules (XPM's), and VAV Modular Assemblies (VMA's) for terminal boxes make up the controller product offering.  Check out the CG/CV Product Bulletin for more information.  The robust and powerful programming includes question and answer style for typical sequences and customization available to meet all programming needs.
