Issue due to daily sudden power off

Issue due to daily sudden power off

The customer is connecting PR21's power cable directly to the production line's power source, which is daily powered On in the morning, and powered Off in the evening. Due to this daily sudden power Off, PR21 is not performing well after being powered On next day (not able to to ping or communicate). PR21 can work well after being restarted. Howerver, the customer don't want to manually restart PR21 everyday.

Is there any document mentioning clearly that PR21 should not be suddenly powered off like this?

Thank you very much.

Hi Peter, thank you for your reply. There are about 50 devices PR21 installed in customer factory (not Bosch plant). These PR21 are connected to production line's power source properly as your diagram. However, everyday, the production line is powered On at 8:00AM and is powered Off at 6:00 PM. Hence, PR21 is powered Off without being shutdown properly by its own power switch. Some devices (PR21) works well next start, some device doesn't. The customer asked me to fix those PR21 which is not working on next start. I want to show to the customer that they are treating the device in improper way (power off the power source of the production line, without shuttingdown the PR21 properly). However, the customer says that there is no documents/user manual mentioning that.
