About Transition States
Of the seven test states in MPT, there are four Entering and Exiting states:
Entering Stopped, Exiting Stopped, Entering Hold, and Exiting Hold. These
states could be described as “transition states”; that is, when MPT is leaving one
state and entering another, such as changing from a Running state to a Holding
state. Sometimes these transitions are instantaneous, but they still exist.
How long the test remains in a transition state depends on the test parameters you
have chosen, using two separate windows: the Execution tab on the MPT
Options Editor and the Command Options tab on the Station Manager’s
Channel Options window.
MPT Execution tab
Use the MPT Execution tab to select the following Command Hold and
Command Stop Behaviors:
• Stay at Level
• Ramp to Mean
• Ramp to Zero
• Taper to Mean
• Taper to Zero
Station Manager
Command Options tab
Use the Station Manager Command Options tab to set the times for these
behaviors:
• Taper Times
• Ramp Times
• Begin/End Times
• Setpoint/Span Times
See the MTS 793 Control Software manual (PN 100-147-130) for more
information.)
Example
The Entering Hold state lasts as long as it takes the system to move from the
Running state to the Holding state. If you chose Stay at Level, the Entering Hold
state would be instantaneous. If you chose Ramp to Mean or Taper to Mean,
then this state would exist for a longer time because time is needed to transition
from the current level to the level state.
