Hi there,
I have a PPT50 secured by a password. After leaving application (e.g. by the default gesture) the password dialog is displayed, but touching the “Update” button the update script is called without requesting the password.
Is there some setting to avoid starting the unwanted update process?
Thank you
Hello Lubos,
There is no way to disable the update button on the service page password pop-up. An update is only executed if a valid update is found on a USB and it’s only possible to install signed images by default for security. If having the update feature more secured is a requirement for your application here are some other steps you can take to make it harder to access:
- Disable opening service page with a gesture. By doing this the only ways to access the services pages is by connecting a USB mouse and pressing left and right buttons simultaneously or changing the start mode. B&R Online Help: Service Page Gestures
- Physically block the USB ports so a USB drive can’t be inserted unless allowed.
Hope this information helps.

Hi Ryan,
Thanks for the information - you confirmed what I suspected.
I didn’t want to turn the gesture off, I don’t always have a USB mouse with me when I’m servicing a customer.
And you are correct that Update is only done with valid USB media, so in practice it should not overwrite the Image.
The suggestion to suppress the USB interface is interesting. Do you mean blocking it via some Automation Studio function? What would that be?
Thanks, Ryan
Hi
I want to reply to it: the keyword was “physically”, so specifically not with AS or in software generally, but with actual hardware. Google keyword (I don’t want to advertise any specific product) is “usb port lock”
Hope that helps as well
