For second issue regarding 4PP281, please download the user manual from our website because the size of the doc is bigger than 10MB so I can’t attach that to your post:

Could you share with us all product name and the serial number?
Thanks
Ciao

This is HW with CompactFlash. If you are lucky, maybe only the CF is broken. So you can try unplugging the old one and plugging in a new one (but for this you need the original project with your application), or restore it from a backup image.

That is what you can do. Otherwise, you need to contact the machine producer. B&R can help you restore the CF card, but you still need the project or image.

Hi @Jarek , what is status of your topic, can you update us?
