Messages
The message function is almost identical to the alarm function, but less in its priority. There
are two messages available, when the message function was activated. These two messages
can be parameterized separately. The dynamic range of the message function is much bigger
than the one of the alarm function. So it is also possible, to realize running turn over. Both
messages have an own communication object of the size 1 bit. These communication objects
are shown in the chart below:
