Use of USB devices
• Wait at least ten seconds between removal and reconnection of USB devices.
• When using standard USB devices, bear in mind that their EMC immunity level is
frequently designed only for office environments. These USB devices are adequate for
commissioning and servicing purposes. Only USB devices suitable for industrial use are
permitted for use in the industrial field.
• USB devices are developed and marketed by their manufacturer. The manufacturer
provides support for these USB devices. The terms of liability of the individual vendors or
suppliers apply.
Note
Functional problem with USB port
Malfunctions may occur if you use a potential-free system structure and connect an external
USB device with its own power supply to the USB interface. In this case, use external USB
devices without their own power supply or a non-isolated system structure.
Excessive rated load on port
A USB device with too high a power load may possibly cause functional problems.
Observe the values for the maximum load of the USB interface. You can find the values in
the section "Technical specifications of the IFPs (Page 109)".
