This screen is arranged in three sections.
SECTION ONE: Longitudinal Feedback Control
This section, across the top of the display, is a duplicate of the controls on the Feedback Control display, and they work the same way. It contains the controls as one line item for the associated longitudinal feedback. Please see the Help... for the Feedback Control display for a description of these indicators and control buttons.
SECTION TWO: Feedback Detail Graphic
This middle Section shows a graphic of the position of the devices used in the associated Feedback application. The device name is a button which brings up the related device display. There is a square of color that indicates whether the device is currently used in the Feedback. Green means it is in-use, Grey means it is not used. If it is Red or Yellow, then the device or state is in a warning or error condition. See the tabular display below to see if the device or state is operating near or outside of its limits.
This section also contains the individual state loop controls. you may choose to Activate or Disable the state loops individually using the Activated/Disabled toggle button for each state.
SECTION SECTION THREE: Tabular Data Display and Controls
This section shows a table of the lower limit, current value, and upper limit of measurements collected for the associated Feedback, and the calculated States and actuator values. When the feedback is on the current values will update continuously. If a device or state is operating near its limits, or out-of-range, the current value will be highlighted with a corresponding yellow or red box around it. You can enter new limits on-the-fly using these inputs.

The on-the-fly setpoints can all be used as a vernier to scan around the setpoint.
The on-the-fly setpoints are:
DL1 Energy: The desired Energy for Dog Leg 1, in MeV.
...
DL2 Energy: The desired Energy for Dog Leg 2, in MeV. This is most often used as a 'vernier' around the actual DL2 Energy value.
The setpoints that can be changed when the feedback is off are:
L2 Chirp: use this PV when the feedback is inactive, the same as you would the L2 Chirp MeV PV on Joe's display.
