mona:StopAcquisition did not stop area detector #39

Closed prjemian closed 6 years ago

prjemian commented 6 years ago

mona verifier issued a stop that was handled by the RunEngine. Good. 

In [58]: ERROR:ophyd.signal.mona:StopAcquisition:Subscription value callback exception (EpicsSignal(read_pv='mona:StopAcquisition', name='mona:StopAcquisition', value=1, timestamp=1534615026.826786, pv_kw={}, auto_monitor=False, string=False, write_pv='mona:StopAcquisition', limits=False, put_complete=False))

But, the stop handling did not stop the area detector acquisition: these additional steps are needed

caput 2bmbPG3:cam1:Acquire 0
caput 2bmbPG3:HDF1:Capture 0
caput 2bmbPG3:HDF1:Enable 0

perhaps other things associated with det.unstage()

Also, handling does not reset mona:StopAcquisition
