The only way to stop a running infinite sequence is to program another sequence.

python ~weaver/lcls2-new/ psdaq/psdaq/seq/rixgeneratory.py --periods 1.0 0.01  (units in seconds).  Generates three files beam.py, codes.py and codes2.py in the current directory which should be programmed with "seqprogram".

...

Running a standalone daq step-scan (no hutch-python).  The number "9" corresponds to two bits: 9=8+1, or 9=(1<<3) | (1<<0), where 3 and 0 are the two sequence engines that have been programmed with seqprogram above.  The "-g" argument is for the readout groups in the partition (2,5): 36=(1<<5) | (1<<2).

python ~weaver/lcls2-new/ psdaq/psdaq/control/rix_bluesky_scan.py -p 2 -C drp-srcf-cmp004 -g 36 --detname andor_vls_0 --seqctl DAQ:NEH:XPM:3:SeqReset 9 DAQ:NEH:XPM:3:SeqDone
