Floor Level Network Controller
Description
The Floor Level Network Controller (FLN Controller) is
an integral part of the APOGEE® Automation System.
It is a user-programmable Automation Level Network
(ALN) device dedicated to serving as a coordinator for
up to 96 Field Level Network (FLN) devices. It
communicates on the ALN, passing information about
FLN devices to other ALN devices. Up to 100 FLN
Controllers can communicate on the ALN.
The FLN Controller is similar to the Modular Building
Controller (MBC); however, the FLN Controller does
not have termination modules for field input and output
points. All physical points controlled by the FLN
Controller must be terminated in FLN devices.
Information about the environment of your facility is
gathered by the FLN Controller via FLN devices such
as Terminal Equipment Controllers (TECs), Unitary
Controllers (UCs), Digital Point Units (DPUs), Fume
Hood Controllers (FHCs), and Differential Pressure
Monitors (DPMs). The FLN Controller can execute
control programs that handle operator commands and
requests, and make control management decisions.
Features
• Economical method to coordinate FLN
communication to all FLN devices
• ALN communication to all field panels and
Insight® workstations on the network
• Transparent viewing panel on the enclosure door
to view the status indicator LEDs
• Two industry-standard RS-232 ports supporting
connection of multiple operator devices, such as
modems, laptop computers, display terminals, and
printers
• Power receptacles at the box to provide ease of
use for modem and laptop computers at the field
panel
• Custom program sequences to match HVAC
equipment control applications
• Advanced Proportional Integral Derivative (PID)
loop tuning algorithm for HVAC control to minimize
oscillations and maintain precise control
• Built-in energy management applications and
Direct Digital Control (DDC) programs for
complete facility management
• Comprehensive alarm management, historical
data trend collection, operator control and
monitoring function
