Change DLT Lable Variant Via Logic

I have been using the following command via HG to change DLT labels:-

SetStringIBSystemIO("Label Group Text", 254, 56, "WIN BED 4", 0, 'Vlux Open');

This has worked fine, until we have alter some other key lables to a custom font size, now the labels changed by HG are at a different size to the rest.

So the question is can the above command be altered to set the font size along with the text.

Or

I have made 2 variants for the group in question 1-Vlux Open 2-Vlux Closed is there a way to make the dlt alter the variant displayed via logic ?

To Recap

Sorry for being a bit slow but the xmas partying has left my head a bit scrambled, to get it straight in my head.

So if you alter the label text via logic with the command above you can only use 1 font and size.

And you cannot get the dlt to swap to a different variant via logic on the fly

 

That's correct.

As Ashleigh says, any custom font size/style is implemented in the DLT as a bitmap. Only the default font size/style is treated as text. When HG bashes out the new label it is sent across the bus as a text string, which the DLT applies the default font/style to when displaying. The DLT has a fairly small processor and having enough memory and grunt to run all the fancy font footwork would definitely push the price up.

You can't switch variants from within HG. It's a Toolkit-commissioning setting in the DLT on a per-unit basis.

 

To recap

And I take it there is no way to alter the default font in the dlt ?

 

Nope, it's compiled into the code that runs in the graphics processor.

Do the public docs for labelling explain how to send a label bitmap over the bus? If so, then you may be able to do it that way.
