## Startup options on the web server Several tools are being added to the web server to add efficient startups. ### Save and restore for camera settings Without a save and restore tool for SwissFEL camera settings, this tool sets listed camera settings for **Basler** and **PCO edge** cameras. Please note setting the configuration will stop selected running cameras for around 1 second and overwrite current settings. ### Operation The configuration restore script is set from https://sf-photodiag-test.psi.ch/ under the **Startup** tab. Cameras are grouped (e.g, Beamline Aramis, Beamline Athos.....), and by pressing the desired button all cameras under that group name are set **if their configuration file contains a `hardware_configuration` dictionary** ### Camera group The tool uses the existing `group` field in the camera configuration. This is how the cameras are group by the screen panel etc. Currently used groups are: - Beamline Aramis - Beamline Athos Any group can be easily added to the tool. ### Database After filtering by camera group, the tool uses the camera configuration files on the camera server (accessible via CSM or API) as a database for the settings. Setting are contained in a dictionary called "hardware_configuration" in the camera configuration: ```` "hardware_configuration": { "EXPOSURE": 9.9, "HSSPEED": 1, "REGIONX_START": 1, "REGIONY_START": 500 }, ```` where the item names are the suffix of the PV name of the camera PV to set. For example, for the camera `SARFE10-PSSS059` the item in the dictionary above `EXPOSURE` sets the PV `SARFE10-PSSS059:EXPOSURE` to 9.9. To add settings for a desired camera, simply add the dictionary (if not already present) to the camera config file and add the items that should be restored.
