When fastscanning, the workflow is aborted because the beamline energy is not achieved within the prescribed tolerances. During investigation of this problem, it appears that there is latency between the motor level PVs and the beamline energy PV. This issue is likely related to the interaction of Acquaman with the SGM subnet. Other issues that may be related are the loss of connection between Acquaman and beamline IOCs requiring gateway reboot, and the occasional observation of the undulator and exit slit tracking PVs being rapidly switched on and off for no apparent reason.
