Help for Beam-Based Feedback Control
This is the overall Controls display for the beam-based feedbacks in MATLAB.
This screen is arranged with each feedback system as one row of buttons and displays. Feedbacks of similar type are grouped within a box. The buttons and displays are arranged in columns.
TOP SECTION: Power and Charge Control
This section includes the controls required for the laser power application and bunch charge feedback. In addition to the controls described per column below, this section includes the Laser Power, Camera Intensity and Bunch Charge setpoints, and displays the actual power readback. These are available for the operator to change the setpoints without having to bring up the detailed display.
There is a Status: string which displays warning or error statuses produced by the running Matlab feedback application.
LOWER SECTION:
This section has controls for the remaining feedback systems, as described by column below.
COLUMN ONE: Detailed Display
The button under this column has the name of the feedback on it. This button will bring up a detail screen for the named feedback. The colored square next to this button displays the current status of the feedback. Green means its ON, yellow means there is a warning on one of the feedback actuators, states or measurement devices, red means it is ON with an error condition. This area will display the OFF string when the feedback is off. Next to this color indicator, there is a number displayed that should be continuously incrementing (updating every 2 seconds) as long as the feedback is running. It will get stuck at one value if the matlab feedback crashes. If this number gets stuck then Stop then Start the crashed feedback with the corresponding control buttons (as described below)
COLUMN TWO: Feedback Control
Three control buttons are shown under this column. The Start button will start the feedback system. This is an INVASIVE operation, the feedback systems change Klystron and Magnet settings. The Enable/Disable toggle will enable or disable the feedback if it is running. This toggle is available to temporarily disable a feedback without shutting it down. The Stop button will stop the running feedback.
COLUMN THREE: Hostname
This column displays the name of the host computer on which the feedback matlab script is running.
COLUMN FOUR: Restore Actuators
The button under this column will execute the Restore Actuators application for the given feedback system. This application sets the feedback system actuators back to their original settings (saved when the feedback system was last started). This is also an INVASIVE operation.
COLUMN FIVE: Configuration
The button under this column will execute the Configuration application for the given feedback. This application allows the user to reconfigure the devices used, tolerances, matrices etc. for the given feedback. The configuration application also allows the user to collect or edit the reference orbit used by the feedback. In most cases this application is for the experienced user only.
STATUS STRING:
At the lower left of each feedback group there is an area where the matlab feedback can display a status string. If this string indicates an error in the matlab processing it will be surrounded by a yellow (warning) or red (error) box.
Global Watcher Status: This status square appears in yellow or red if the Global Watcher application has indentified an error condition. Please see the Watcher window for an error description.
LAUNCH SUMMARY PLOTS: this button will bring up a display of summary Bunch Charge and Launch feedback plots. As summary, only the States of the feedback are plotted.
LONGITUDINAL SUMMARY PLOTS: this button will bring up a display of longitudinal summary feedback plots. As summary, only the States of the feedback are plotted.
