The Avi-on
BACnet Link


The BCS Link interfaces between Building Control Systems via BACnet IP to provide two-way building control integration.  An Internet connection to the cloud is not required.

Supported Data Types

Data Export:

Device Status

Send real time device status and dimming level changes from any Avi-on device

Motion Triggers

Send an update to the BCS any time a motion sensor is triggered

Daylight Values

Send an update to the BCS anytime a daylight sensor updates the dimming level on a group of lights

Fixture Energy Consumption Data

Send energy consumption data to the BCS every 15 minutes on all data points enabled with the appropriate energy monitoring Avi-on fixture controller (AVI-IFAC and AVI-XFAC)

Control import:


Adjust dimming levels or on/off status to groups of lights or individual lights, trigger scenes

Special Schedules

Turn on and off devices for groups or individual devices for special holiday or override schedules.

Demand Response

Enable pre programmed demand response modes from a BCS trigger

Emergency Mode Triggers

Trigger emergency lighting mode in emergency circuits from a BCS (or any BACnet IP compatible) control signal

* Raw readings in 15 minute increments

To get kWh/15 minute interval consumption it is necessary to subtract the latest reading from the prior reading.  A blank reading means data was not received for that interval.  If the reading was lost, but the device was operating, the next interval that reports will include all the energy used since the prior received interval, so lost intervals will not cause loss of data.  The interval is broadcast every 15 minutes at the end of the interval (latency <3 seconds).  The receiving system should time stamp based on local system time.

When a device register value exceeds 5242880 or on a power cycle, the register value will reset to 0 and start again.  Interpreting the data requires “rollover” logic to recognize these rollovers and produce a correct value.  This is standard logic in BCS systems designed to handle ordinary meter reading data.
