When I simulate it from my PC on the web server(changed the path) when I insert the USB to the PC port the led that I have inserted works correctly but when I connect it to the screen does not work the led that I put. Thanks in advance '' export async function LED_usb_ENCENDIDO() { let rutaUsb = "/media/simatic/X61"; // Ruta de la unidad USB específica de la pantalla HMI let ledUsbConectado = Tags("Led_USBConectado"); function verificarUSB() { HMIRuntime.Trace("Verificando conexión del USB en la ruta: " + rutaUsb); HMIRuntime.FileSystem.Browse(rutaUsb, "", true).then( function () { ledUsbConectado.Write(true); // Activar LED HMIRuntime.Trace("USB detectado: Conexión exitosa."); } ).catch( function (errorcode) { ledUsbConectado.Write(false); // Apagar LED let errorMsg = HMIRuntime.GetDetailedErrorDescription(errorcode); HMIRuntime.Trace("USB no conectado o inaccesible: " + errorMsg); } ); } HMIRuntime.Trace("Inicializando verificación de USB."); ledUsbConectado.Write(false); verificarUSB(); } PD: TIA V18 HMI SCREEN V17.0.0 (MTP 1500 UNIFIED COMFORT 6AV21283QB060AX1)

But it is available in V18 and later. Kind regards Stefan
