Dali Light secuence - josep - 06.02.2017

Hello,

We are doing a temporary project for an exhibition and I need to make a script that sends different values of regulation during a specific time to create light effects in an installation,

(for example. initial value 20% -> (10sec) -> 60% -> (10sec) -> 75%)

these sequences will have to be repeated without stopping when turning on the LogicMachine.
I would like to know how I can do these LM regulation ramps and how do I run it at startup?

Thank you very much.

Hi Josep,

Try this in a resident script, interval time doesn't matter.

Code:
outputaddress = '1/1/1' -- byte object

-- set step values

value1 = 20

value2 = 40

value3 = 60

value4 = 80

value5 = 100

-- set init value

value = value1

-- set delay

delaytime = 10

-- loop always

while true do

  -- check if value 1 needs to be written

  if value == value1 then

    value = value2

    grp.write(outputaddress, value1)

  -- check if value 2 needs to be written

  elseif value == value2 then

    value = value3

    grp.write(outputaddress, value2)

  -- check if value 3 needs to be written

  elseif value == value3 then

    value = value4

    grp.write(outputaddress, value3)

  -- check if value 4 needs to be written

  elseif value == value4 then

    value = value5

    grp.write(outputaddress, value4)

  -- check if value 5 needs to be written

  elseif value == value5 then

    value = value1

    grp.write(outputaddress, value5)

  -- fallback when value not valid

  else

    value = value1

  end

  -- delay loop 

  os.sleep(delaytime)

end

When changing one of the declared values you need to restart the script.

If you reboot LM the sequense starts automaticly again as long as your resident script is having the active state.
