energy-cli is commad-line-interface to set and tune beamline 2bm mode changes between mono, pink and white beam

$ git clone https://github.com/xray-imaging/2bm-ops.git
$ cd 2bm-ops
$ python setup.py install

in a prepared virtualenv or as root for system-wide installation.

To set the beamline energy to 20 keV:

$ energy set --energy-value 20

to list of all available options:

$ energy -h
  usage: energy [-h] [--config FILE] [--version]  ...

  optional arguments:
    -h, --help     show this help message and exit
    --config FILE  File name of configuration file
    --version      show program's version number and exit

Commands:

  init         Create configuration file
  set          Set energy
  save         Associate the current beamline positions to an energy value
               and save in a config file
  status       Show status

The beamline status is stored in ops2bm.conf. You can create a template with:

$ energy init

osp2bm.conf is constantly updated to keep track of the last stored parameters, as initalized by init or modified by setting a new option value. For example to set the beamline to the last energy configuration

$ energy set

to list of all energy save options:

$ energy save -h

If the beamline has been manually optimized after setting a preset energy configuration, you can save the current beamline status in a custom config file with:

$ energy save --energy-value 27

The config file name is named ops2bm_mono_27.0.conf. You can restore the beamline positions for the optimized energy configuration with:

$ energy set --config ops2bm_mono_27.0.conf

In testing mode, the motor positions are printed but not actual motor motion occurs. To enable testing mode set:

TESTING = True

in epics_move file, then re-install with:

$ cd 2bm-ops
$ python setup.py install
