Machine Interface¶

Interface with DOOCS¶

LISO provides the MachineInterface abstraction to allow interacting with a real machine through its control system. DOOCS, the Distributed Object-Oriented Control System, is used ubiquitously at DESY.

An example code snippet is shown below:

from liso import EuXFELInterface
from liso import doocs_channels as dc

m = EuXFELInterface()

m.add_control_channel(dc.FLOAT,
                      'XFEL.RF/LLRF.CONTROLLER/VS.GUN.I1/PHASE.SAMPLE',
                      'XFEL.RF/LLRF.CONTROLLER/CTRL.GUN.I1/SP.PHASE')

m.add_control_channel(dc.FLOAT, 'XFEL.RF/LLRF.CONTROLLER/VS.GUN.I1/AMPL.SAMPLE')

m.add_control_channel(dc.FLOAT, 'XFEL.MAGNETS/MAGNET.ML/QI.63.I1D/KICK_MRAD.SP', no_event=True)
m.add_control_channel(dc.FLOAT, 'XFEL.MAGNETS/MAGNET.ML/QI.64.I1D/KICK_MRAD.SP', non_event=True)

m.add_diagnostic_channel(dc.FLOAT, 'XFEL.DIAG/CHARGE.ML/TORA.25.I1/CHARGE.ALL')
m.add_diagnostic_channel(dc.IMAGE, 'XFEL.DIAG/CAMERA/OTRC.64.I1D/IMAGE_EXT_ZMQ',
                         shape=(1750, 2330), dtype='uint16')
