System Error A_1#4.0 on a PP865a HMI
The fault is coming all the time and can only be reset by restarting the HMI
The system has being for several years without any problem, it seems to be something to do with memory, but what and how to solve?
the customer is far away and I don't have access to the HMI.

Hi!
Do you use a USB flash device for external storage?
High temperature or frequent write/erase cycles are limited.
Good luck!
