Introduction
A USB port 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
port. The front-sided USB port 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 port 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

The USB peripherals are developed and marketed by individual vendors. The respective
