Hello,

i try to use the function to invert (toggle) a boolean. It doesnt work.

Here is my code. What is wrong?

export function Schaltfläche_3_OnKeyDown(item, keyCode, modifiers) {
let tag1 = Tags("Motor1_Hmi.swtManual");
tag1.write( !  (tag1.read() ) );
}

Best regards,

Wolfgang

 let tag1 = Tags("Motor1_Hmi.swtManual");
tag1.Write( ! tag1.Read() );

The .write() needs to be .Write() and .read() needs to be .Read()

welcome to the fun of javascript :)
