control,

“sleep

mode”

control,

or

any

other

types

of

control.

In

an

exemplary

embodiment,

control

logic

module

414

operates

based

off

of

information

stored

in

one

or

more

databases

of

control

computer

252

and

stored

in

memory

404

or

another

memory

device

in

commu

nication

with

control

computer

252.

The

database

may

be

populated

with

information

based

on

user

input

received

at

graphical

user

interfaces

and

control

logic

module

414

may

continuously

draw

on

the

database

information

to

make

con

trol

decisions.

For

example,

a

user

may

establish

any

number

of

zones,

set

schedules

for

each

zone,

create

ambient

lighting

parameters

for

each

zone

or

?xture,

etc.

This information

is

stored

in

the database,

related

(e.g.,

via a

relational

database

scheme,

XML

sets

for

zones

or

?xtures,

or otherwise)

and

recalled

by

control

logic

module

414

as

control

logic

module

414

proceeds

through

its

various

control

algorithms.

[0049]

Control

logic

module

414

may

include

any

number

of

functions

or

sub-processes.

For

example,

a

scheduling

sub-process

of

control

logic

module

414

may

check

at

regular

intervals

to

determine

if

an

event

is

scheduled

to

take

place.

When

events

are

determined

to

take

place,

the

scheduling

sub-process

or

another

routine

of

control

logic

module

414

may

call

or

otherwise

use

another

module

or routine

to

initiate

the

event.

For

example,

if

the

schedule

indicates

that

a

zone

should

be

turned

off

at

5

:00

pm,

then

when

5:00

pm

arrives

the

scheduling

sub-process

may

call

a

routine

(e.g.,

of

wireless

interface

module)

that

causes

an

“off”

signal

to

be

transmitted

by

master

transceiver

258.

Control

logic

module

414

may

also

be

con?gured

to

conduct

or

facilitate

the

completion

of

any

other

process,

sub-process,

or

process

steps

conducted

by

control

computer

252

described

herein.

[0050]

Referring

further

to

FIG.

4,

device

interface

module

410

facilitates

the

connection

of

one

or

more

?eld

devices,

sensors,

or

other

inputs

not

associated

with

master

transceiver

258.

For

example,

?eldbus

interfaces

416 and 420

may

be

con?gured

to

communicate

with

any

number

of

monitored

devices

418 and

422.

The

communication

may

be

according

to

a

communications

protocol

which

may

be

standard

or

proprietary

and/or

serial

or

parallel.

Fieldbus

interfaces

416,

420

can be

or

include

circuit

cards

for

connection

to

process

ing

circuit

402,

jacks

or

terminals

for

physically

receiving

connectors

from

wires

coupling

monitored

devices

418 and

422,

logic

circuitry

or

software

for

translating

communica

tions

between

processing

circuit

402 and

monitored

devices

418

and

422,

or

otherwise.

In

an

exemplary

embodiment,

device

interface

module

410

handles

and

interprets

data

input

from

the

monitored

devices

and

controls

the

output

activities

of

?eldbus

interfaces

416

and 420

to

monitored

devices

418

and

422.

[0051]

Fieldbus

interfaces

416 and 420 and

device

interface

module

410

may

also

be

used

in

concert

with

user

interface

module

408 and

control

logic

module

414

to

provide

control

to

the

monitored

devices

418

and

422.

For

example,

moni

tored

devices

418

and

422

may

be

mechanical

devices

con

?gured

to

operate

a

motor,

one

or

more

electronic

valves,

one

or

more

workstations,

machinery

stations,

a

solenoid

or

valve,

or

otherwise.

Such

devices

may

be

assigned

to

zones

similar

to

the

lighting

?xtures

described

above

and

below

or

controlled

independently.

User

interface

module

408

may

allow

schedules

and

conditions

to

be

established

for

each of

devices

418

and 422

so

that

control

computer

252

may

be

Apr.

10,

2014

used

as

a

comprehensive

energy

management

system

for

a

facility.

For

example,

a

motor

that

controls

the

movement

of

a

spinning

advertisement

may

be

coupled

to

the

power

output

or

relays

of

a

controller

very

similar

if

not

identical

to

con

troller

204.

This

controller

may

be

assigned

to

a

zone

(e.g.,

via

user

interfaces

at

touchscreen

display

254)

and

provided

a

schedule

for

turning

on and

off

during

the

day.

In

another

embodiment,

the

electrical

relays

of

the

controller

may

be

coupled

to

other

building

devices

such

as

video

monitors

for

informational

display,

exterior

signs,

task

lighting,

audio

sys

tems,

or

other

electrically

operated

devices.

[0052]

Referring

further

to

FIG.

4,

power

monitor

450

is

shown

as

coupled

to

?eldbus

interfaces

416

in

an

exemplary

embodiment.

However,

power

monitor

450

may

also

or

alter

natively

be

coupled

to

its

own

controller

or

RF

transceiver

451

for

communicating

with

master

transceiver

258.

Power

moni

tor

450

may

generally

be

con?gured

to

couple

to

building

power

resources

(e.g.,

building

mains

input,

building

power

meter,

etc.)

and

to

receive

or

calculate

an

indication

of

power

utilized

by

the

building

or a

portion

of

the

building.

This

input

may

be

received

in

a

variety

of

different

ways

according

to

varying

embodiments.

For

example,

power

monitor

450

may

include

a current

transformer

(CT)

con?gured

to

measure

the

current

in

the

mains

inlet

to

a

building,

may

be

coupled

to

or

include

a

pulse

monitor,

may

be

con?gured

to

monitor

volt

age,

or

may

monitor

power

in

other

ways.

Power

monitor

450

is

intended

to

provide

“real

time”

or

“near

real

time”

moni

toring

of

power

and

to

provide

the

result

of

such

monitoring

to

control

computer

252

for

use

or

reporting.

When

used

with

power

monitor

450,

control

logic

module

414

may

be

con?g

ured

to

include

logic

that

sheds

loads

(e.g.,

sends

off

signals

to

lighting

?xtures

via a

lighting

?xture

controller

network,

sends

off

signals

to

monitored

devices

418 and

422,

adjusts

ambient

light

setpoints,

adjusts

schedules,

shuts

lights

off

according

to

a

priority

tier,

etc.)

to

maintain

a

setpoint

power

meter

level

or

threshold.

In

other

exemplary

embodiments,

control

logic

module

414

may

store

or

receive

pricing

infor

mation

from

a

utility

and

shed

loads

if

the

metered

power

usage

multiplied

by

the pricing

rate

is

greater

than

certain

absolute

thresholds

or

tiered

thresholds.

For

example,

if

daily

energy

cost

is

expected

to

exceed

$500

for

a

building,

control

logic

module

414

may

be

con?gured

to

change

the

ambient

light

setpoints for

the

lighting

?xtures

in

the

building

until

daily

energy

cost

is

expected

to

fall

beneath

$500.

In

an

exemplary

embodiment,

user

interface

module

408

is

con?g

ured

to

cause

a

screen

to

be

displayed

that

allows

a

user

to

associate

different

zones

or

lighting

?xtures

with

different

demand/response

priority

levels.

Accordingly,

a

utility

pro

vider

or

internal

calculation

determines

that

a

load

should

be

shed,

control

logic

module

414

will

check

the

zone

or

lighting

?xture database

to

shed

loads

of

the

lowest

priority

?rst

while

leaving

higher

priority

loads

unaffected.

[0053]

Referring

now

to

FIG.

5,

an

exemplary

control

activ

ity

for

a

system of

controllers

as

described

herein

is

illus

trated,

according

to

an

exemplary

embodiment.

As

described

in

FIG.

2B,

lighting

?xtures

(or

more

particularly

controllers

for

lighting

?xtures)

can

be

grouped

into

zones.

Rather

than

reporting

motion,

ambient

light,

or

other

sensed

conditions

back

to

master

transceiver

258

for

processing

or

action,

con

trollers

such

as

controller

204

may

be

con?gured

to

broadcast

commands

or

conditions

to

other

RF

transceivers

coupled

to

other

controllers

in

the

same

zone.

For

example,

in

FIG.

5,

lighting

zone

I

includes

four

controllers.

When

motion

is

detected

by

sensor

210

of

controller

204,
