Relay Output Assignment Window
This is not a subwindow of the Measuring Point menu, but an independent window that can only
be reached from the Measuring Point menu. It is used to assign relay outputs to the input selected
in the Measuring Point menu. This window also provides the same function as the
Relay Output
window.
The top three rows of the menu cannot be accessed here and are only shown for information. The
behavior of a relay output depends on its parameter settings and the settings of the appropriate
measuring points.

The functions of the individual window elements are described below:

on the MDO as well as the common alarm relay 'Inhibit' starts
flashing with a frequency of 0.5 Hz.
