Client Library for Control Systems

• Define the API of the Lima client library
• Review with the Bliss team
• Implement the library on top of the device servers

The basic idea is to centralized and hide the implementation details of the Lima distributed application with a client library in Python.

from Lima2.Client import Detector
from uuid import uuid1

det = Detector("id00/limacontrol/sam_simulator", "id00/limareceiver/sam_simulator1")

# Construct parameters with default values
acq_params = det.AcqParams()   # Acquisition parameters
proc_params = det.ProcParams() # Processing parameters

# Get current parameters from DS
acq_params = det.getAcqParams()   # Current acquisition parameters
proc_params = det.getProcParams() # Current Processing parameters

# Acquisition
uuid = uuid1()
det.prepareAcq(uuid, acq_params, proc_params)
det.startAcq()
det.stopAcq()

det.stateAcq()
evt = det.getStateChangeEvent() # Returns a gevent.Event used to track 

# Processing
uuids = det.listPipelines() # Returns a list of all processing pipelines UUIDs
det.abortPipeline(acq_uuid) # Abort a given processing pipeline
det.erasePipeline(acq_uuid) # Erase a given processing pipeline

nb_frames_acquired = det.nbFramesAcquired() # Returns the number of frames acquired
nb_frames_xferred = det.nbFramesXferred()     # Returns the number of frames transferred

# Miscellaneous
version = det.version()  # Versions info
det_info = det.detInfo() # Static detector info
