About Test Recovery
MTS MultiPurpose TestWare® MPT Options Editor 75
The snapshots of the test state and status can be used to restart a test that was
interrupted by an event (for example, a power failure or interlock).
About Test Recovery
When you enable the recovery feature, the application updates a recovery file
(saved in the MPT specimen) at the intervals you specify.
Snapshot intervals can be set using the program state changes (includes Run to
Stop or Stop to Run state changes, including interlocks) and time intervals that
you specify.
You can use a recovery file to restart a test even if the test was running during the
last snapshot. You cannot restart tests if they have completed or have been reset.
What is saved Information saved to the recovery file includes:
• A copy of the procedure. (It is possible to edit a procedure, then run it
without saving it. In this situation, the test status contains the information
used in the execution, not the original procedure.)
• The active group and individual processes. It also identifies how much of
each process is complete.
• The current program state (Run, Hold, Stop). When recovering a test, if the
program was running or holding, the test is restored in the Stop state.
• The state of the sequence counters and the channel counters.
