USB port baud rate
For scan times faster than 50 ms you need to increase the baud rate of the USB port. The default
baud rate of 9600 gives a read write cycle of about 45 ms. By increasing the baud rate to 38400 this
time is reduced to 7 ms, which makes it possible to use scan times down to 10 ms.
To change the baud rate you
–configure the baud rate in the BaudRate attribute in the Arduino_Uno object.
–change the baud rate value in the Serial.begin() call in the pwr_arduino_uno sketch and upload the
modified sketch to the board.

I/O Configuration
Don't use digital channels 0 and 1, which seems to interfere with the USB communication.
The card is configured in Proview with the rack object Arduino_USB and the card object
Arduino_Uno.
