Hello,

I am using a barcode scanner(wireless) Zebra DS3678 with USB type communication. I have connected the scanner to the USB port of Siemens TP1200 HMI. I have used an IO field to read the barcode data. Its working well. The problem is if I remove the scanner there is no indication that the scanner is disconnected form HMI. I want to create an alarm indicating the scanned is disconnected . Can anyone help me with this?. Thank you in advance.

Regards
