Struggling to build an expression

Ignition

Last time, I learned about BinEnc. I'd like to take it a bit further and need help with the syntax.

I have 2 DINTS...
If DINT 1 > 0... 1
if DINT 2 > 0... 1
Then, BinEnc(DINT 1 Result, DINT 2 Result)

How do I write that? I'm using it to change the color and text of a multi-state indicator.

binEnc(
	DINT_1 > 0,
	DINT_2 > 0
)

However, you might want to use this state elsewhere. If these 2 DINTs are part of a UDT (which they probably should be, since it seems like they are related), you can make an expression tag and bind to that to control your style customizer.

To expand further,

case(
  binEnc(
    DINT_1 > 0,
    DINT_2 > 0
  ),              // value to inspect
  0, "Off",       // case 0, return 0
  1, "Running",   // case 1, return 1
  2, "Fault",     // case 2, return 2
  "BAD STATE!"    // default return
)

This would work, if you wanted to do a binding for each property, but I think @brians.laptop just wants the resulting INT so he can use it in a style customizer (or at least that's what he should do).

Brians should probably add the vision or perspective tag to his original question!

Thanks to both of you. Its pretty simple stuff... but I'm trying to copy the functions on an existing Red Lion HMI, on a similar plastic sheet extruder. One DINT has 32 warnings, and the other DINT has 32 alarms. Green: No Alarms, Yellow: Active Warnings, Red: Active Alarms. If there are both, warnings and alarms, then the flasher flashes Yellow and Red for 1000 ms each. Thanks again for the info.
