Two USB host interfaces are available at the operating device.
Operation of the USB ports at the operating device
When using input devices not intended for industrial use (e.g. key-
board, mouse), the operational safety is limited. Input devices inten-
ded for home or office use are also part of the devices not intended
for industrial use.
Connect only USB devices that meet the USB2.0 specification.
For the specification of a suitable cable, refer to "Universal Serial
Bus Specification Rev. 2.0".
The max. cable length is 2.5 m.
