3.4.8 Combined machine trigger on "alarm group" AND "PLC variable"
Description of functions
The combined machine trigger contains the alarm group trigger and PLC variable
trigger, which are automatically linked by means of a logic "AND".
Its special feature is a configurable temporal indeterminacy between the alarm
group trigger and the trigger for the PLC variable, in which the trigger is yet to be
initiated. The individual trigger functions are described in the same way as each of
the triggers.
