Panels interface description
All of the panels have interfaces on the front and rear sides.
Front-mounted USB interface – standard USB 2.0
The USB interface is located at the front of the panel under the rubber cap. This interface
can be used, for example, to connect an external keyboard or an external mouse.
Although additional USB devices (memory sticks, floppy drives, etc.) can be used, they can
impair real-time capability (see the note below).

The user can read the effect on the system software on the "Latency" tab in the
SIMOTION P state tool. It displays there whether the installed software violates the real-time
conditions. In case of doubt, please contact your local SIEMENS sales representative.
Note
Using a distributed configuration with the Panel PC Remote Kit reduces the data rate at the
USB interface on the SIMOTION panel front.
