Tuning/Engineering Procedures for CCF Displays

This section provides instructions for tuning/engineering functions for CCF
displays. These functions are generally restricted to users with greater authority.
Two levels of tuning are supported by the system. The first level is provided by the
Loop Detail Display. This display provides the means for basic loop tuning such as
gain or limit adjustments. The second level is provided by the Loop FCM Display
and runtime versions of the Loop Definition and FCM templets. These displays
provide the means for more comprehensive tuning, and for changing loop
configurations during runtime (while the system is online). Refer to
Tuning Displays for a Continuous Loop

Tuning Via the Loop Detail Display

You can change tuning, alarm, limits, and loop parameters via the Loop Detail
Display. More advanced tuning functions, not supported by the Loop Detail Display,
are provided via the Loop FCM Display where you can access the Loop Definition
Templet and the Loop FCM Templets for each FCM in the loop.
Changing a Tuning Parameter
Tuning parameters include: gain, reset, preact, and adaptive mode. Adaptive mode is
a read only field and cannot be changed.
To change a tuning parameter (value entry):
1.
2.
3BUR002418-600 A
Select the FCM on a Loop FCM display.
Again, you may have to adjust some preliminary parameters as a prerequisite
for changing the parameter that you actually want to change.
Select the entry field, and then enter the new value via the keyboard.
Press Enter to accept the new value.
Select the Gain value field in the Tuning area of the display. This displays a text
entry field within the current Gain field.
To change the gain value, enter the new value via the keyboard, and press Enter.
The Gain field is updated with the new value.
