USB 2.0 host "USB1", "USB2" (X9)
The two USB host ports are made for attaching USB peripherals. They provide a max. current of 0.5 A each.
Pin wiring:
NOTE
USB port overload by excessive power consumption
Machine failure and/or data loss
Only attach USB peripherals whose total power needs do not exceed 0.5 A or supply
external power to the USB peripherals by adding an active hub to the line, for example.
NOTE
Electromagnetic interference in industrial environments
Machine failure and/or data loss
Mind that the USB interface is not designed for use in industrial environments but just as
a service interface for loading software updates or data up into or down from the control
unit.
USB sticks
USB stick users should consider the following points:
The USB port is mechanically designed to support up to 1,000 plug/unplug operations.
Pulling off a USB stick during operation is allowed only when no more file operations are being performed.
Failure to comply may render the USB stick useless!
If a program still has a file open when the USB stick is pulled, you will find it impossible to close the directory
that the file belongs to. In this situation, the system will not respond to any file or directory operation requests
because it would be expected to read from a device that is no longer available. Therefore, before pulling off
the USB stick, you should always ensure that no program still has an open file loaded from the stick.
