Multiple Parallel Events within a State
If multiple events are defined within a state, all events are simultaneously active and
operate in parallel as long as that state is active. Once a branch to another state occurs,
all events in the first state cease to be active.
There is one exception to this rule due to a special event ("State Entrance") which is
intended to provide a one-time action or set of actions that occur only when the state is
initially entered. Among other applications, this can be useful for following which state
the system is in at any given time (e.g., you can have the system beep when it enters a
particular state).
Multiple Parallel Sequences
Again, note that within a given sequence only one state is active at any given time, but
different sequences can be simultaneously active. There can be three simultaneously
active processes, which are as follows:
•
Global Rules (which has only one state)
•
Sequence 0 (which can contain multiple states)
•
Sequence 1 (which can contain multiple states)
Events For either Global Rules or Sequences, there is a
list of event types that you can choose from,
which is presented to you each time you "Click
here to add an event". With one exception (see
below), the list of events is identical between
Global Rules and Sequences.
The events are explained in more detail in this
section.
