Sudarsan, Peter, Dave: PSL model changes
The h1psliss, h1pslfss and h1pslpmc models were modified to downsample all 32kHz channels to 16kHz. This resulted in 10 32kHz channels changing to 16kHz with the distribution: ISS=1, FSS=4, PMC=5. The models were restarted and the DAQ was restarted. This resulted in a science frame size reduction of about 20MB per 64 second science frame (2%). The restarted models were burt restored to 9am PST today.
Dave: DMT broadcaster
Following last week's ISS model change, the H1BROADCAST0.ini file was changed to replace the obsolete H1:PSL-ISS_PD[A,B]_OUT_DQ with the calibrated H1:PSL-ISS_PD[A,B]_REL_OUT_DQ. Also the obsolete H1:LSC-OMC_DC_OUT_DQ was removed from the DMT.
Hugh, Dave: HEPI pump controller channels
Following Hugh's software change on the corner station HEPI pump controller EPICS system, a new EDCU INI file was added to the DAQ. Hugh has updated the MEDM screens and is updating the autoBurt.req file.
Dave: Restart of H1SLOW-F1FE EPICS gateway
Following the restart of h1ecatx1 this morning, subsequent restarts of the DAQ EDCU did not establish new connections to this IOC. I restarted the EPICS gateway between the EDCU and the Beckhoff IOCs which prompted the EDCU to re-establish a connection. It took several minutes for the reconnection to complete. Initially the number of disconnected channels went from 1,951 to 81, then took a further minute to reduce to zero.
Dave: DAQ restarts
To support the above work the DAQ was restarted three times this morning. On restart 1 and 3 the data concentrator was very slow on restarting (several minutes) while restart 2 proceded at the usual pace. While waiting for the slow restarts I had time to check for duplicate channels (none) and any errors in log files (none).
Jim, Dave: replace broken thunderbolt monitor at operator station
I collected the repaired Apple thunderbolt monitor from Alpha Computers this morning, Jim installed it at the operator station. We are looking into a tether cable solution for strain relief.
