General Description:
Most main plant control systems within large buildings
require feedback variables such as temperature from the
Fan Coil Units (FCUs) or Variable Air Volume (VAVs) units
on each floor, to give the correct demand signal to the
Boilers, Chillers and Air Handling Units (AHUs).
In a typical building with over 500 floor controls, it is not
feasible to connect the feedback temperature from each
controller back to the main plant. This would
flood the backbone network with messages as each sensor
in the entire building transmits its data back to one controller
in the plant room.
The InfraTrol AVG 5x5 averaging module collects all the
temperatures for five individual zones and provides the
average value of each zone for transmission to the main
plant, greatly reducing network traffic on the backbone.
The unit also provides a relay function for a enable signals
from the main plant controls. A single enable message is
sent to each floor via the InfraTrol AVG relay function block
using acknowledged service, and the output of this network
relay function is connected to each floor control. The relay
can repeatedly (using a configurable heartbeat timer)
broadcast the signal to the floor controls without using up
network bandwidth on the backbone.
