Figure: DeltaV Operate View of the Analog Tracking Function Block
Faceplate (AT_fp)
The faceplate shows the configured analog tracking conditions (there
can be as many as 16 conditions). The columns in the faceplate report the
following information about the conditions:
First Out - A red
arrow next to a condition indicates it was the first condition that evaluated
to True.
Condition - The
configured description for the condition. Descriptions of inactive conditions
are in light gray text.
Delay On - The time
configured to delay the output of the condition when it evaluates to True.
Delay Off - The
time configured to delay the output of the condition when it evaluates to
False.
Delay Timer - Shows
the Delay On or Off time remaining after a condition's state changes.
Value - The track
value configured for the condition.
Bypass - A check mark indicates if the condition has been
bypassed. Gray boxes indicate the T_HIGHER_MNGn is True.
Reset Required -
Indicates if a reset is necessary to unlatch the condition after the
condition's expression evaluates to False. When a condition that requires a
reset becomes inactive, the
Reset button appears. All of the boxes are
gray to indicate that changes cannot be made from the faceplate.
Hold in Manual -
Indicates if the downstream PID block is set to Manual mode when the
condition's output is latched.
