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.
