Engineer Tuning Displays For A Continuous Loop - ABB 800xA Operation

Section 3 CCF Displays
Changing a Device Parameter
Device parameters include: Simulation Mode, Override Mode, Lock State, and
Field State. Field State is a read only field and cannot be changed. The other device
parameters can be switched between ON and OFF in the Device Values area.
Changing Deadband Parameters
Deadband parameters include: Eng Deadband, Output Deadband, and Deviation
Deadband. Each of these parameters requires a value entry.

Engineer Tuning Displays for a Continuous Loop

For tuning and online engineering functions that are beyond the scope of the Loop
Detail Display, the following set of engineering displays are provided on an
individual basis for each loop:

Engineer tuning of continuous loops is initiated by using the Loop FCM Display.
Loop FCM Display
The Loop FCM Display,
class modules (FCMs) that make up the loop.
Each FCM in the loop is represented by a block on the display. Both the block type
and the name given to the FCM at configuration time appear in the block. Each
block contains status information for the FCM which can be a combination of the
information in
3BUR002418-600 A
The Loop FCM Display shows the sources of inputs, the destination of the
results, and the status of the FCMs. This display is dynamically updated with
runtime data. The display also provides access to the runtime version of the
Loop Definition and FCM templets where actual tuning/engineering changes
are entered.
A runtime version of the Loop Definition Templet provides the means to
modify some fields that were originally configured via the Loop Definition
Templet during control database configuration.
Runtime versions of the FCM Templets for the loop provide the means to
modify some fields that were originally configured via the FCM Templets
during control database configuration.
