USB Link Controllino make reset when RaspPI3 ShutDown

[Vax]

Good morning, sorry for my poor English, I’m French !

All is in the title.

I use Controllino Maxi linked with Raspberry Pi3 by USB.

I use Pi with touchscreen for MMI (IHM in french). When I shutdown the Pi, the Controllino make reset and I try to understand how and why.

As I read in the User manuel :

“The main function of the USB port is to program the CONTROLLINO. Inside the CONTROLLINO there is a USB to UART converter which generates a virtual COM-Port on the PC. You can also use this port to give data to a terminal or another program.”

Maybe this USB to UART converter make a DTR signal when the USB link is closed…

Tanks a lot by advance.

Xavier.
