I'm trying to set visibility of an object inside a faceplate dependant on two separate tags. First tag is a byte, second tag is a bool.

I'm using TIA Portal v16, building a WinCC unified faceplate. The script I have so far is:

export function Rectangle_13_Visible_Trigger(item) {
let tag1 = Tags("tag1");
let tag2 = Tags("tag2");

let tagValue1 = tag1.Read();
let tagValue2 = tag2.Read();
let vis = ScreenItems("Rectangle_13")

if tagValue1 == 1 & tagValue2 == 0 {
     vis.visible = 1;
}

}

I'm a bit new to scripting in general, so any help would be appreciated.

Take a look at some of the script examples found here they may help:
