nLight ECLYPSE Reference Manual

nLight ECLYPSE™
BACnet Object Quick Reference Guide

The nLight ECLYPSE™ controller is a BACnet Building Controller (B-BC) certified device that acts as the IP interface for an nLight lighting control system,
including support for both nLight and XPoint Wireless devices. It provides a BACnet interface (optional) that is BACnet Testing Laboratories (BTL) listed for
system integration to a building management system through BACnet/IP and BACnet MS/TP.

The following chart provides the available BACnet object types and description of each object.

occupancy sensor is occupied or unoccupied (e.g. nCM PDT 9,
XPA CMRB). For multi-pole occupancy sensors (e.g. nCM 9 2P),
two BACnet objects will be available.

The relay state provides feedback on whether the relay in a
device is open or closed (e.g. nPP16 D, XPA CMRB).

The dimming output level provides the intensity of a dimming
devices (e.g. nPP16 D, nLight Enabled Fixture, nSP5 PCD, nIO
D, XPA RL1).

The measured light level provides an analog foot-candle
reading from a device with a photocell (e.g. nCM ADCX, nWSX
LV, nCM PDT 9, XPA SBOR).

When a photocell device is programmed to turn lights off or
inhibit lights from turning on, photocell
inhibiting provides indication when the photocell has provided
this “off/inhibit” command. This point is available with nLight
devices only (e.g. nCM PC).

The active load provides an analog power consumption reading
of the lighting load connected to a device with the current
monitoring feature (e.g. nPP16 IM, XPA RL1, XPA SBOR).

The dimming input level provides an analog reading of the
input percentage on the signal to an input device. This point is
available with nLight devices only (e.g. nIO 1S).

The online status provides indication whether a device is
communicating with nLight ECLYPSE controller or not.

The system profile object provides feedback on whether a
profile is active/inactive.

Aggregate state of all occupancy sensors broadcasting on
an occupancy channel: Unoccupied = all occupancy sensors
on the channel are unoccupied. Occupied = one or more
occupancy sensors on the channel are occupied.

The channel relay state provides feedback on whether the
relays in a channel are open or closed.

This value represents the average of all dimming output levels
on the respective switch channel. Writing to this value is the
equivalent of sending an nLight switch “go to level” command.

This setting is only exposed if a valid license for ADR has been
added to an ECLYPSE. This value represents the current status
of a system responding to demand response.

Px = Indicates device pole. Most devices only have a single pole

(P1), devices with secondary pole will display P1 and P2.

NOTE

1. A BACnet object is available after a user has completed
programming of the initial artifact (profile, channel, etc.).

BV = Binary Value

BI = Binary Input

AV = Analog Value

2. nLight AIR requires that a switch be associated with output
devices in a group before channel objects will be created.

AI = Analog Input

COV = Object is capable of providing “Change of Value” notification

MS = Multistate
