N30 Supervisory Controller
Date Last Saved: 1/26/2004 10:59:08 AM

Product Name(s): N30 Supervisory Controller
Product Description: The N30 Supervisory Controllers are designed to monitor and supervise controllers on the secondary N2 network. They communicate with workstations and with each other using the primary peer-to-peer, BACnet/IP. The N30 meets BACnet Conformance Level 4, providing data sharing and alarm management with non-JCI BACnet control systems
Product Application(s): The N30 regularly polls all connected N2 controllers to update information and share points as needed, and then coordinates building-wide control functions via commands to these SCUs. The N30 has the capacity to execute pre-programmed and custom routines for global building control. It also performs trending, totalization, and alarm processing functions.

Additional Information
* Items in NV memory are not lost upon power or battery failure. Other types of NV memory such as EPROM, NOVROM, etc. do not directly impact system performance.
Can trend data be stored in this controller? Yes
How many total trend values can be stored? Up to 1 MB RAM limit
What is the controllers role in trending? Programming resident within N30 gathers and stores trend data on-board. At set intervals, data is sent by the N30 to workstation for archival.
Can controller be programmed to 'push' data to archive or are trends 'pulled' from controller?
When full, does controller automatically send up trend data, overwrite data, or stop logging data? Information not provided

Programming Method(s)

(See also 'Software' Form)

The N30 uses Facilitator M-Tool, the programming toolset for N30 and related ASCs. (This software replaces Configuration Tools/Winpro)

Scheduling

(See also 'Software' Form)

The N30 provides the schedule for itself and connected secondary controllers. Events can be programmed for any day of the week, holiday, or calendar date.
