About Sequencing Processes
Working with MPT Processes 88
In your procedure or group table:
• Use the trigger signals available in the Start control to determine when each
process starts.
• Use the trigger signals available in the Interrupt control if you want to
specify a test event that interrupts the process.
• Use the trigger signals available in the Procedure (or Group) is done when
control to determine when the procedure ends.
Procedure start and
interrupt signals
All signal lists in your main procedure table include the <Procedure>.Start and
<Procedure>.Interrupt signals.
If you set the Start or Interrupt control to <Procedure>.Start, the process starts
or interrupts when the procedure starts.
Note In group tables, the controls are labeled <Group>.Start and
<Group>.Interrupt, and they pertain to the start and interrupt of that
particular Group process.
Done signals When an individual process ends, it generates a “done” signal. These done
signals are labeled process name.Done in your Start, Interrupt, and Procedure
is done when lists.
For example, if you created a segment command process named Ramp Up, the
done signal that appears in your signal lists would be labeled Ramp Up.Done.
Each process automatically generates a done signal when the process completes
its programmed function, or when it is interrupted by another signal. Process
done signals are typically used to specify the start of another process and/or the
end of your procedure.
Special process signals In addition to done signals, some data acquisition processes can also send out a
“buffer full” signal (indicating when the data buffer is full), and some event
processes can send out a “trigger” signal (indicating when the process is
triggered).
A buffer full signal or trigger signal can also be used to specify the start of
another process, the end of the test, or to interrupt other processes.
Fan-in and fan-out
processes
You can select more than one signal in each Start, Interrupt, and Procedure is
done when list to create a “fan-in” process. The process (or procedure) responds
if any of the selected signals is detected.
