USB support of the operator interfaces has been introduced for releases from RTSetup version 2.00 onwards. It is now possible to save all device data on a USB stick or to restore the operator interface system from the USB stick.

|
Unless you want to load a device image only insert the USB stick once the Communication menu pops up.
|
If you insert the USB stick before then, the following will happen:
ET/MT-3x6 and ET-208
Stick with recovery image
|
The device loads the image.
|
ET/MT-3x6
Stick with/without
device data
|
The application is only started once the stick has been removed and a function key has been pressed.
|
ET-208
Stick with/without device data
|
The device will start the following communication menu.
|
|
If a USB stick is inserted in the X4 USB-i interface and is recognised by the system, the communication menu will display the additional keys<F4> to <F6>.
|


Further information displayed is the "Volume Name" as well as the total (Total: xxxx MB) and available (Free: xxxx MB) memory of the USB stick.
|
If none of the <F4> bis <F6> keys is pressed within a preset interval (to be set via NEW AUTOEXIT TIMEOUT (System parameters ⇩), the communication menu is automatically terminated and the operator interface will start the application.
In general, any USB stick with protection class Ex-i can be used for this functionality. Detection or transmission errors may occur, however. Only the USB sticks supplied by R. Stahl HMI Systems GmbH can guarantee a flawless USB support.
There are two ways of saving data on the operator interface. Users can save either ONLY the operator interface project or also ALL OTHER files.
