These scans use the same "step" idea described above for EPICS PV step-scans, but instead alter a detector configuration object on each step.  Currently this has been done for the EPIX area detector to take data in the various gain ranges.

Script Control of Run Stop/Start

One can control the DAQ (e.g. to stop and start runs on a timer) with scripts like this:

#!/bin/bash                                                                                      
while [ 1 ]
do
echo going to configured
daqstate -p 0 -P tmo -C drp-neh-ctl001 --state configured
sleep 5
echo going to running
daqstate -p 0 -P tmo -C drp-neh-ctl001 --state running
sleep 600
done
