Match DALI Group Levels

Hi All,

So in my setup I'm using DALI for all the Lights, interfaced with a Dali Gateway.

What I want to achieve is when I change the level of a Dali Group (which is mapped to a c-bus group), the individual dali channel level follows that group level. E.G. If I increase the Dali Group "All Lights", the Individual lights which are part of that group, should follow. (That way i don't have to turn a light "on" to turn it off).

I have a PAC which i can use to build some logic - What I'm conscious of is flooding the DALI network with confusing messages and it being even more painful. I'm guessing the best way is to put a 4second delay on the 'Once' logic so that the individual channels follow only once the current even is completed. Though this seems a little crude.

Or is there a way i can update the level- without actually sending the level to the DALI gateway?

Let me know if anyone has had any clever ways to deal with this. Noting that C-Bus scenes to control multiple DALI lights somewhat sucked.

 

Did you set the dali gateway way to use the lighting application or are you using the dali application?
I do what you mention without any logic using the lighting application (If I understand you correctly).

 

I'm using the lighting application with the gateway.
Effectively I'm trying to sync multiple group levels.. let me know your secret.

 

You can do what you explain with out logic
Have you programmed you DALI ECGs to be part of a group.
Each DALI ECGs has
A Unique short address
16 DALI groups it can be part of
16 scene levels it can go to
the C- Bus Group addresses can be mapped to these.
Results is that if you map a DALI group to a C-Bus group All the DALI lights in that group respond together.
So if your stuff aint working and reading what you say I presume that you have not programmed your DALI ECGs groups or mapped them to a C- Bus group
It may be that you have only mapped the Short Addresses hence controlling one light with one C-Bus Group Address

Colin has answered exactly what I was suggesting. Thanks Colin.

 

Ah- So I have it working this way already. What I'm trying to achieve is:
C-Bus Group 1 controls DALI Group 1
Dali Group 1 has 4 lights - Assigned to C-Bus Groups 2, 3, 4 and 5.

If I bring up C-Bus Group 1, the lights assigned to c-bus groups 2,3,4 and 5 all come on, however the level of those individual groups all remains at 0%. I want to make it so if C-Bus Group 1 = 100%, Groups 2,3,4 & 5 also = 100%

Hopefully that makes more sense...

 

As you can see in the attached picture, the kitchen dali lights A.36,A.37,A38,A33 are all part of the same dali group #9 and mapped in the dali gateway to a single c-bus group address

 

Have a read of this thread, I think it covers a very similar situation.

Exactly that, though there doesn't appear to be a solution. I'm thinking my best bet is to build some logic that pauses 5 seconds, then sets the corresponding lights to the same level.

Thx.

 

Sounds like a good plan, share your logic or ask for help, between us all we may come up with a good solution for you.

 

So my attempt at programming this logic was short lived...

What's the best way to detect "On Level Change" - at the moment I'm thinking along the lines of:

Code:

Once
(GetLightingLevel("Dali Broadcast") > 0%) then

Will this trigger every time it is changed above 0%?

My next stump was how do I set the group level to match another group level? Effectively I want to be able to say SetLightingLevel("LX Group - Lounge" = "Dali Broadcast")

Pointers greatly appreciated!

 

No. It needs to go back to 0% before it can trigger again. Try then HasChanged function.

Use TrackGroup

 

Ok - That made things super easy... It didn't seem to like having a Delay so I scrapped that concept - seems to work as expected. When the broadcast level changes, all the groups follow... then all the groups can be changed independent of that broadcast level.

Code:

{Match Dali Levels on Broadcast Change}
if HasChanged(GetLightingLevel("Dali Broadcast")) then
begin
TrackGroup(254, 56, "Dali Broadcast", "LX Group - Lounge");
TrackGroup(254, 56, "Dali Broadcast", "LX Group - Entrace");
TrackGroup(254, 56, "Dali Broadcast", "LX Group - Kitchen All");
TrackGroup(254, 56, "Dali Broadcast", "LX Group - Study");
TrackGroup(254, 56, "Dali Broadcast", "LX Group - Entrance");
end;

{Ensure Broadcast Level is 0 when all LX Groups are off}

once (GetLightingState("LX Group - Entrance") = OFF) and
     (GetLightingState("LX Group - Kitchen All") = OFF) and
     (GetLightingState("LX Group - Kitchen Bench") = OFF) and
     (GetLightingState("LX Group - Kitchen Hall") = OFF) and
     (GetLightingState("LX Group - Kitchen Room") = OFF) and
     (GetLightingState("LX Group - Lounge") = OFF) and
     (GetLightingState("LX Group - Study") = OFF) then
begin
  SetLightingState("Dali Broadcast", OFF);
end;

 

To test if a number of groups are off, create a scene with their values set to 0. Then just use the sceneIsSet function.

i.e. once sceneIsSet("Your scene") then ...
