Floor Level Network Controller (FLNC)
Date Last Saved: 12/13/2007 8:59:24 AM

Product Name(s): Floor Level Network Controller (FLNC)
Product Description: The FLNC is a Supervisory Interface (SI) device that is similar in memory capacity to the Modular Building Controller (MBC) primary controller, but without on-board I/O capability. The FLNC resides on the primary ALN network, supervises communications, and hosts controllers on the secondary FLN.
Product Application(s): The FLNC can be used as a standalone SI to support secondary controllers or can be paired with newer-generation MEC primary controllers to add custom programming and I/O strategies (the latter similar to the functionality of the MBC, but with fewer options). As a supervisory interface, the FLNC provides central monitoring, control, and global energy management functions for up to 96 secondary control units on the FLN.

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? Trend storage is limited to available RAM.
What is the controllers role in trending? Programming resident within SI gathers and stores trend data on-board. At set intervals, data is sent by the SI to workstation or called by the 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? Old data is overwritten if controller trend data memory fills before being called by archive workstation.
