Shutter Relay & DLTs

I want to set the DLT text to "open" and "close" when using a shutter relay, it puts the group DLT text in both gangs.
Is there a better way then having to use variants ??

Labels are specific to a Group Address and they apply to all units using that group. The mechanism for being able to have different labels on buttons controlling the same Group is Variants.

In your case, you have 2 buttons controlling the same Group. To set this up you assign the 'Open' label to the first key, change the second key to variant 2 and then click the edit label button to change the text label for the second button to 'Close'.

Which part of Variants doesn't exactly meet your requirements?

 

Hi Newman
Which part of Variants doesn't exactly meet your requirements?

Its the number of them, have over 70 shutters and that many DLTs and some of the shutters appear on more than one DLT.
So that a lot of data entry and if config has to be change more typing, not sure by fingers that long.

The variants are stored in Toolkit ???
So if I set var1 to "open" and var2 to "closed" when I use the same shutter group in second switch will it use the store data ??

That works, just means i have to use the drop box but save a lot of typing.
That will do me

Yep

 

Newman
Even better will add to my Toolkit generator program,
if App = shutters jam in the var1 and 2 DLT Text.
Then I not have to type anything.

makes a big difference when you have someone to toss ideas around.

yep

got my system changed and all works fine, forgot to tell you it updated over the 2 networks.

Cool

 

Shutter Relay and DLT
If I have a shutter relay and want to control it from C-Touch and DLTs and want to use a one button and 2 button options.

The C-touch and 2 button option is under control, also you may not be able to see the blind from the DLT position.

So looking at some way to indicate on the DLT which way it going to operate, like change the text.

Would it be true to say changing the text counts in the burn total

Is there a ?get shutter status? command

Can I change the variant text without a burn

Or does the text have to stay fixed and the user run around the corner to see which way blinds going after pressing a button

tks dave

 

I assume you're concerned about EEPROM wear-out. If that's the case, then you're living in the old days, Dave. The EEPROM that stores all the DLT labels is rated for millions of reads/writes. Wear-out is not an issue. You can re-label it to your heart's content.

Changing the in-use Variant is a commissioning-time configuration parameter and it is done on a per-key basis. If a mechanism was introduced to enable the variant to be changed on-the-fly it would also need a mechanism for addressing a specific key on a specific unit.. which we already have... and it's called Toolkit commissioning.

Not specifically, but what you're looking for may be able to be achieved via another means...

If you use the Shutter Relay in Proportional mode instead of Level Translation mode, then the level of the group is an approximation of the position of the blinds. Now, to do this the ramp rate in the key unit and the fail-safe time-out in the Shutter Relay need to be configured so that they're a pretty close match for the run-time of the motor, but once you've got that sorted you can infer the blind position from the group level.

Now, if you're using a single button on a DLT to control a blind like this you'd configure the button as a single-key dimmer. Short presses would fully open/close the blind and you'd get position feedback on the slider of the DLT. Press-and-hold would keep opening/closing the blinds until you released the key, whence the blinds would stop.

The direction of the arrow on the slider shows you which direction the blind will go next. Because the key is configured as a dimmer key, after 15 seconds since the last press the dimming/blind direction will default to dimming downwards/closing the blinds.

If you really, really want the DLT text to tell the user which way the blinds will go next (i.e. the arrow direction on the slider is not sufficient for you) then you still have an option. If you're watching and tracking all these state changes on the group in something like the logic engine, and monitoring how long it was since the last bus event on the group, it would be possible to update the group label appropriately.

Its my heart the I am worried about, guess I will have to move to Townsville.

The rest about to test.

thanks again

I hear a glass of red is good for that from time to time too.

Oh, and the other neat thing about Proportional mode is that the wiper position on the slider bar of the DLT also approximates the blind position.

 

Hi
Have got the DLTs set for 1 and two button control, DLT text on 1 button option still a work in progress.

tks for your help
