3.4.4 Machine trigger on "alarm group"

Description of functions
The "alarm group" trigger can be used to respond to all alarms programmed in the
control. These alarms also include the user area for alarm numbers that are used
to program the machine functions for machine diagnostics purposes. If machine
diagnostics are not performed on the basis of alarm numbers, there is no option of
linking these error messages here. The alarm numbers that initiate triggers can be
entered individually, in groups or in series.
It is also possible to remove individual alarms or groups from a selection. In
addition to this, conditions that are not meant to initiate a trigger on their own can
be linked (e.g. if a particular alarm is only meant to initiate a trigger in Automatic
mode).
