5.9 Data Transition Behaviors
Data Transitions: In simplest terms, a Data Transition takes place whenever new data meets
old data. In more formal terms, a data transition is where Record Mix Data
transitions to Read Mix Data and vice versa. This means a transition takes
place when Read Mix Data transitions to Record data (such as at a punch-
in) and when the Record Data transitions to Read Mix Data (such as a
punch-out).
Note: Data Transitions are not limited to punch-in and punch-out locations.
Last Recorded Value: The Last Recorded Value is always the current value of the control at the
time it is punched out. However, it should be noted that this value might
have been set well before the actual punch-out. In this case, the location of
the Last Recorded Value is earlier than the punch-out location.
By definition, the Last Record Value is a Dynamic value. However, it
should be noted that it is a singular, non-moving value.
Understanding Behaviors: One of the key aspects to Au, is understanding where the Last
Recorded Value transitions to and from Read Mix data and how it makes
the transitions.
The “where” behavior is determined in two ways:
• Write To: Where Record Data transitions to Read Mix Data
• Extend Back To: Where Read Data transitions to Record Data
The Last Recorded Value may be applied up to or beyond the punch-out
point. It may also be applied back to the punch-in point or before. These
behaviors will be discussed below.
The “how” behavior is determined by whether the Glide function is On or
Off and the Glide Options enabled.
5.9.1 Write To:
The choice of Mix Pass “Write To:” function determines where the Record
Data to Read Mix Data transition takes place. In essence, the concept is as
follows:
“Take the last recorded value and write it to: _____________!”
The blank can be filled in with one of following “Write To:” locations:
• Punch-out: Apply the last recorded value to the punch-out location
• Next Change: Apply the Last Recorded Value to the location of the
next recorded change
• Level Match: Apply the Last Recorded Value until the it matches the
Read Mix value
• End: Apply the Last Recorded Value to the specified End Time.
These locations are also known as “Write To: Functions.”
Note: Unlike other automation systems, the transition from Record Data to Read
Mix Data does not necessarily have to take place at the punch-out location.
In fact, selecting “Write to Punch Out” is the only time that both happen
simultaneously.
