Bitmaps and text in 8.6.3

[tmoulder]

Greetings!

I'm trying to place a bitmap of a grid (sic) on an HMI in a 570, and drop some text on top of it. The bitmap hides the text. I've fiddled with the draw order with no effect. I know I can make the text into text variables and it will show, but that's... clunky.

Is this a bug in the draw order, or perhaps something that can be changed?

Thanks,

TM

Hi,

It's not clear to me how you are trying to put the text on the screen and why do you not want to use the text variable.

Hi Stein,

In the image attached, the excel-looking cells are 4 copies of a .PNG file I created to get a nice, clean layout of a mass of servo-related data for display.

The text elements in this are not Text objects, they are binary text variables. If I place a standard (non-variable) text object over the bitmap, when I download it to the 570, the text is "hidden" behind the bitmap and invisible on the PLC screen.

If I use a text variable, linked to SB 0, then the text displays correctly as it does in the image I attached. But I don't like doing this, because it's a variable, when all I need is text.

I thought that the HMI Draw Order Utility would allow us to address this, by telling the PLC to draw the bitmap, then draw the text over it. Draw Order does allow me to change this, but it has no effect on what's displayed on the screen once downloaded.

Thanks,

TM

PS: I've discovered that Tahoma is a really great and legible small font for the 570. Just wanted to share...
