Getting Bits From Integer

Ignition
1

I am working in Ignition 8.1.44

I am trying to build a screen where I can show the status of 16 bits from an integer. The integer is a "status" word from a drive, each bit has an individual function.

Right now, I have configured the display to have a custom property of type integer, that way I can use the same screen repetitively. Inside the block, I have laid out 16 labels. Each label has a link established on the background color property. The link is attempting to change the color from black to green.

I have been trying to use a property expression to extract the data I wanted, with the code:
getBit({Root Container.STW1},0)

I am greeted with the error message:

Some older threads I read suggested it was because of needing an update from version 7, but that should not be the issue in this case. I have also tried to use a straight, getBit(3,0) to test - and receive the same error message. I'm open to suggestions on how to tackle this problem.

Try something like this,

if(
	getBit({Root Container.STW1}, 0),
	color(200, 0, 0),		// red
	color(0, 200, 0)		// green
)

The color properties are expecting Java color data types, not integers.
I'm not working in Vision much and I don't know what might not work in version 7.

That works, thank you. I would not have thought to try and script the colors manually.

It's better if you can use a theme where you set the colors in one place for application across the whole project and then select the theme option from the expression. This is easy in Perspective using CSS style classes. I can't remember what the technique is in Vision. Someone will chip in.
