Use of USB devices

• Wait at least 10 seconds between the unplugging and replugging of USB devices. This

also applies in particular to touch control in control units with touch screen panels.

• When using standard USB peripherals, bear in mind that their EMC immunity level is

frequently designed for office applications only. These devices may be used for

commissioning and servicing. However, only industry-standard devices are allowed for

industrial operation.

• Peripherals are developed and marketed by individual vendors. The respective

manufacturers offer support for the peripherals. Moreover, the terms of liability of the

individual vendors or suppliers apply here.
