Note:
It is not possible to select a process screen/special screen if an object with a
higher display priority (see Section 5.8) is displayed at the moment. The request
is terminated with the error information “880B. To select the screen, the request
has to be repeated when the higher priority object is no longer displayed. The
type of object currently shown on the display is provided by means of the
“OBJ_TYPE” parameter in the “HMI API” FB (see Section 4.5).
Jobs with a screen number in the range 128 to 255 are rejected with the error
