Permitted number of communications processors in the PG/PC
The driver software supports a maximum of 1 CP 5711 per PG/PC.
Connecting to the PG/PC
Before you connect the communications processor to your PG/PC, note the following
information:
USB cable
To connect the communications processor, use only the supplied USB cable or another USB
cable suitable for industrial use.
USB connection to PG/PC
To achieve the guaranteed configuration limits with all protocols and at all bus transmission
speeds, you should use at least a USB 2.0 high-speed connector.
You should preferably use the USB connectors located at the back of the housing of your
PG/PC. The front USB connectors usually have a lower signal quality.
We recommend that you do not use any additional USB hubs.

Delete existing configurations before you disconnect the communications processor from
your PG/PC.
You must also log off the communications processor reliably before you disconnect the
communications processor from the PG/PC. Click the "Safely Remove Hardware" icon in the
