To change the background color i have a script in propriety->appreance->background-color. See below the script: let color; let AlarmChannel = Tags("DatiAnalogica.AlarmChannel").Read(); let AlarmHIgh = Tags("DatiAnalogica.AlarmHigh").Read(); let AlarmLow = Tags("DatiAnalogica.AlarmLow").Read(); let WarningHIgh = Tags("DatiAnalogica.WarningHigh").Read(); let WarningLow = Tags("DatiAnalogica.WarningLow").Read(); HMIRuntime.Trace(AlarmChannel); //runtime value = 0 HMIRuntime.Trace(AlarmHIgh); //runtime value = 0 HMIRuntime.Trace(AlarmLow); //runtime value = 0 HMIRuntime.Trace(WarningHIgh); //runtime value = 0 HMIRuntime.Trace(WarningLow);//runtime value = 1 if(WarningHIgh === true \|\| WarningLow === true) color = "255,255,0"; if(AlarmHIgh === true \|\| AlarmLow === true \|\| AlarmChannel === true) color = "255,0,0"; if(AlarmHIgh === false && AlarmLow === false && AlarmChannel === false && WarningHIgh === false && WarningLow === false) color = "242,244,255"; HMIRuntime.Trace(color); //runtime value = "255,255,0" return color; I dont't understand why the value returned is "255,255,0" but the background color of the button is not yellow but it is a default grey.
