http www.lighting.philips.com main subsites dynalite index.wpd dynalite is a lighting and automation control system developed in sydney australia by a company of the same name . in 2009 the company was bought by phillips to become phillips dynalite . the system is commonly used for lighting control building automation home automation and room automation applications and is sold worldwide . contents 1 system design 2 areas and channels 3 communications 4 advantages 5 disadvantages 6 implementations 7 see also 8 sources 9 external links 10 references system design edit the dynalite system consists of user interfaces switches panels motion and heat sensors touch screens and recently ios devices panels are typically standard sized australian or european standard size wall switch plates but instead of normal rocker switches they have buttons of various designs usually with an indicator led inside . output devices dimmers relays led drivers and dali dsi and 0 10 volt controllers . the dimmers range anywhere from a single 240 v relay controller to leading and trailing edge 1 20 amp devices . network backbone devices network connectors extend the range of the network as well as providing integration with other technologies such as amx crestron etc. through the 100 bt device the communication network can be extended over tcp ip networks which also allows the use of computer systems which can integrate into the system . areas and channels edit the network components are all used to set a system of areas and channels . any given lighting fan louvre and relay circuit is a channel in an area . for example a house might have 3 rooms . each room is called an area . the kitchen may contain overhead lights a range hood fan and lights over the bench . these three are called channels . those areas and channels are in states called presets . in preset 1 typically all lights etc. are fully on in preset 4 all of the lights are off . this is all customisable either by the programmer or if it has been allowed by the end user as well . so sending area 3 preset 4 will turn off the lights in area 3 room 3 . sending area 3 preset 2 will set the lights to a low level which is customisable . channels can also be sent presets aside from the preset of the area to which they belong . area 3 preset 4 turns off the lights then area 3 channel 7 preset 1 will turn that light back on . communications edit dynalite components communicate using dynet . the physical layer consists of a modified rs 485 tia eia 485 a serial bus running along cat5 cable blue and blue white carry the hot and cold signal respectively orange and orange white carry 12 v dc green and green white carry 0 v brown and brown white are unused . end of line termination is required 1 dynet 1 is the most commonly used protocol over the bus being messages of 8 bytes of data the 8th byte being a checksum . commonly there are two types of message sent via dynet 1 logical and physical . logical messages talk to areas and channels and physical messages talk directly to the devices . these 2 are typically called 1c and 5c messages on account of the first byte of their message . a 1c message consist of 1c area data 1 oppcode data 2 data 3 join checksum area is the logical area the message is to control . oppcode defines the action to be taken on the area . join is a bitswitch which can be used to filter out selected channels . an oppcode of 00 to 03 means the action is to send the given area into preset 1 to 4 plus 8 times the value of data 3 over the time specified by data 1 and data 2 . an oppcode of 0a to 0d means the action is to send the given area into preset 5 to 8 plus 8 times the value of data 3 over the time specified by data 1 and data 2 . that gives a possibility of 8 255 presets . a usual job uses 4 to 8 and generally preset 4 is reserved to off or all to 0 % . dynet 2 is used mainly to upload data to devices on the network . it allows larger messages of data to be sent significantly reducing lag time . advantages edit each device contains its own programmable logic controller and follows the peer to peer model the main advantage of this is that there is no reliance on a single central controller the system is capable of a high level of resilience and therefore well suited to situations where total failure could be a safety issue such as lighting systems in public places . the message on change system only sends a message every time a lighting state is to change as opposed to the protocol dmx which is constantly streaming the entire data map . this allows for much more devices on a single bus but also leads to missed messages as below . as most of the dynet is openly published it is possible to integrate with third party devices . disadvantages edit the dynet protocol offers no error correction or transmission control each network message is sent on a best effort basis . this means that if a transmitted message is corrupted or missed by a receiving device there is nothing to pick up that the message was not received but also makes for much faster communication and response to user input in ideal situations . the design opens the possibility of devices missing messages . in the case of a user pushing a button to turn on a light this does not present a large problem as the user will probably notice and press the button again but if it is an automated message say from a timeclock there is potential for an important message turning on outside lights of a shopping center to be missed . the usual workaround for this is to simply send the important message twice or more . the previous dynalite programming software dlight 2 commonly in use up to 2011 and still sometimes used for older equipment was built progressively upon a windows 3.11 application and hides many undocumented keyboard shortcuts which are necessary to program a system . the envision editor was launched in 2010 and is designed to be more intuitive and easy to use . it is designed for programmers it is not expected that end users will be able to set up their own systems one needs training usually free provided by dynalite distributors .
