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).

Note
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
When using standard USB peripheral devices, please bear in mind that their EMC immunity
level is frequently designed for office applications only.
Such devices are suitable for commissioning and servicing purposes; however, industrial
components are recommended for normal operation in industrial environments.
NOTICE
IP65 degree of protection can no longer be guaranteed for an externally connected USB
device. You can only assume a degree of protection IP20. This also applies if the rubber
seal on the front-mounted USB port is damaged or missing.
