openACN: ACN standard “ANSI E1.17 -2006 Architecture for Control Networks”


ACN standard “ANSI E1.17 -2006 Architecture for Control Networks”•

Open standard for control of devices, aimed at entertainment technology•

Developed by the Entertainment Services and Technology Association

(ESTA). See ESTA's

Control Protocols Working Group

•

openACN features: portable to different processors and IP stacks, support RLP, SDT

and DMP protocols, BSD licence

•

Currently openACN

must be built from source code which is maintained in a Subversion repository. Sourceforge


Typically runs over Ethernet•

The protocol is designed to be layered on top of UDP/IP

and therefore will run over standard, inexpensive Ethernet

and 802.11

(Wi-Fi) network links.•

ACN relies on UDP

in order to pass its messages. Where reliability is required, the Session Data Transport sub protocol allows semi-reliability of only the latest value for a particular "channel".

► Applications•

Commercial Building Automation and Control•

Home Automation and Control•

It may replace DMX

as the control protocol for lighting systems and will be used for controlling more complex devices like video playback servers (media servers)

and audio mixers

and has been proposed as the sole or primary transport for HD-MIDI.

Packets of data are transmitted at 120 kbit/s

with the packet being 14 bytes long with a four byte data payload. RF energy is only transmitted for the 1's on the data, reducing the amount of power required. Three packets are sent at pseudo-random

intervals reducing the possibility of packet collisions. Push switches also transmit a further three data packets on release of the switch push-button, enabling other features such as light dimming to be implemented. [4]

•

This technology also enables a wireless community of battery-free sensors to connect to transceivers that are powered for continuous operation. Therefore it can be used for wireless mesh networking

(nonstandard mesh protocol).►Hardware platform

•

Developed by

EnOcean GmbH

(a spin-off company of Siemens AG

Based around energy scavenging technology. An example is the ability to be powered from Peltier

devices with a minimum of 2 degrees Celsius temperature difference on each side of a 15 mm square Peltier

What is Ethernet AVB?

The IEEE 802.1 Audio/Video Bridging (AVB) is a comprehensive set of standards to enable high quality, low-

latency streaming of time-sensitive applications to provide bandwidth and latency guarantees for streaming and interactive applications. This includes wired (802.3) and wireless (802.11)

These standards specify a means of providing •

Time synchronization (IEEE 802.1AS, Level 2 1588)•

Resource reservation protocol (IEEE 802.1Qat)•

Forwarding and queuing rules (IEEE 802.1 Qav)

The market includes applications requiring Isochronous or streaming service such as Consumer Electronics, Professional Audio/Video, Telecom, Instrumentation, and Automotive.

Current OFDM-based solution has bandwidth problems•

CDMA UWB could be a long range solutions►

Zigbee•

Well suited for MCHAN in many instances but not suitable for all

applications including multiple family dwellings •

Recently partnered with Homeplug

at request of utilities to create a common applications layer for smart energy.►

Protocol Use and Trends in Building Control


Networking Trends in Building Control

Standards in Building Control Networking “Is a bag of hurt”

►Multiple transport layer standards are being promoted for Powerline

and Wireless

►Multiple application level standards are being promoted for Home Automation and Lighting Control

►Unclear application level standardization for Fire & Security and Metering

Building Control Networking Trends

Sub-Segment Wired Trend Wireless Trend

Fire & SecurityInstalled base is primarily UART and

proprietary based, with increasing trend toward Ethernet based systems

Security systems moving towards short range wireless to simplify

installation

Commercial Building Automation

Many existing systems are UART based, but a clear trend towards Ethernet based

BACnet

Wireless is used for hard to wire sensors. Use of existing WiFi

networks is preferred, but may

require too much power

Home Automation

New construction increasingly includes Ethernet, but existing homes are ideal for

Powerline. Lack of an established standard will slow adoption. X 10 is

declining due to low reliability

ZigBee

and Z-Wave compete for adoption as the dominant standard

Utility Meters Competing Powerline

standards for both utility and home connection

Competing standards for utility connection from ZigBee

to WiMAX, with slight trend towards ZigBee

in home connection

Lighting ControlCompeting UART based standards, all require additional connection. X 10 is

declining, and new competing Powerline

standards are slowing adoption

General interest in ZigBee

and Z-

Wave, even some Bluetooth

applications. Expect strong growth with LED lighting due to lower heat

Low level in system connectivity

Expect SPI and I2C to continue to be used for basic connectivity, with a trend towards USB and SDIO for more complex peripherals such as WiFi, firmware

updates, and mass storage
