Analog Tracking function block faceplate (AT_fp)

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.
