Front interfaces
Introduction
A USB interface is located on the front side. For more information, please refer to the
chapter "Operation." Attach an external keyboard or an external mouse, for example, to the
USB interface. The front-side USB interface supports the standard USB 2.0.
Caution
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.
Notice
When the cover over the USB interface is opened in order to connect a USB component, the
degree of protection for the device is no longer guaranteed.
When using standard USB peripherals, please bear in mind that their EMC immunity level is
frequently designed for office applications only. These devices are adequate for
commissioning and servicing purposes. However, only industry-standard devices are
allowed for industrial operation.
The 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.
