triggering lights

can somebody please tell me how to,
what i am trying to do is to cascade on 8 pairs of lights for a driveway, what i want to do is at a press of one button would be to start some kind of timer, the first pair of lights come on, then about 2 seconds later the next pair come on ect ect untill all 8 pairs of lights are on, in the installation i do have a mk 2 b/w touchscreen with logic, and a few dlt, i can use either or both.
thanks

 

You can do this sort of thing without having to revert to logic.

- Make sure all 8 pairs of lights are assigned to independent relay channels, but assigned to the same Group Address.
- Configure a key unit or your C-Touch to ramp the group address on over a 20 second period.
- Configure the turn-on thresholds in the relay so that the first channel turns on at minimum, the next channel turns on at 10%, the next channel turns on at 20%, etc.

As the group address ramps from 0% to 100% over 20 seconds, the first pair will turn on immediately, the next pair 2 seconds later, then next pair 2 seconds later... etc.

 

Ok, Finelly i'm getting around to do this now, and i've got it all done, but without me sounding dumb,
how do i assign the inderpendant relays to the same address group?
i can create the address group, but how do i assign then to it?

 

In the drop-down box for each channel you can select the C-Bus Group Address. All you need to do is select the same group for each channel using the drop-down boxes.

In the attached screenshot I've also shown how to configure the turn-on thresholds.
