DALI devices feedback statuss

[AlexLV]

Hello,

begin working with DALI - did not find on forum how to receive feedback from DALI devices.

I need status of lamp - is it ON or OFF, if ON - receive to LM dimming level. With other gateways also possible receive status of DALI ballast - is it working or not, also error if lamp is broken. What we can do with LM DALI bus and RS485/DALI interface?? Found DALI commands, but may be somebody can provide examples or a little more details??

Also recommend to developers add 2 possibilities to DALI interface - broadcast FLASH command - all lamps will flash with interval 0.5 sec as example..(Possible make script but I still learning LUA). Very need for first startup - we will see which lamps not receive DALI commands or not added to interface (but for this not sure - may be in broadcast mode all DALI devices will flash, even thous which still not added in device list in LM??). Second possibility - when we found devices and begin to set up them - Flash possibility for selected device fill help us to see we work with device we need. Manually switch on/off not so comfortable, I have more 250 lams in my project, installation of them made other persons..

Hi,

Just curious:

Why don't you use a KNX DALI gateway like MTN6725-0001 that has all the features you need already included in the application?

Also the DALI processes are then located into another device and definitly result in a much more robust setup of your project.

Is it only to save some small extra investment?

BR,

Erwin

Ervin,

you are correct   These devices I know VERY WELL - want recommend to all of us... I have site where working more than 100 pcs such devices, more than 3300 lams are connected.. During 10 years of sucessful working only 3 may be 4 have some problems.. Now at home I use newest gateway from Merten/ Schneider with letter IP - newest generation of good DALI gateways...


Ervin, you correct twice, just in my new project are used 6 RS485/DALI gateways from LM. A little specific, so I need a little help

You can use this command to get the current value of each ballast (change GW and ballast addresses as needed):

Code:

require('user.dali')
res = dalicmd('internal', 'queryactual', { addrtype = 'short', address = 0 })
if res then
  grp.write('5/0/1', res:byte())
end

The same way you can use querystatus and other commands that have reply mark in this table:

Flashing can be done via a resident script:

Code:

dalicmd('internal', 'arc', { addrtype = 'broadcast', value = 254 })
os.sleep(1)
dalicmd('internal', 'arc', { addrtype = 'broadcast', value = 0 })
os.sleep(1)

If you want to flash a single ballast, just change the addressing parameters to use short address instead of broadcast.

Thank you very much, tomorrow will try to use your code.

But for last a little not understand - I have one RS485 interface. On it I have 6 RS485/DALI gateways from GW0 to GW5. How to address GW I need? As example - how flash all lamps through DALI line connected to GW3 in my case?

First parameter of dalicmd is gateway address, for external ones use gateway id number:

Code:

dalicmd(5, 'arc', { addrtype = 'broadcast', value = 254 })
