WP13213 Jeff, Tom, Oli, Dave:
h1susbs (the original BSFM model) was changed slightly to no longer drive the 2nd LIGO-DAC chans 08-11. This frees these up for use by the BBSS model. At the same time 4 IPC senders and 11 IPC receivers were removed.
Instead of replacing h1suslo12 with a brand new h1susbbss model, with all the associated RGC/DAQ/puppet changes, we chose to keep the h1suslo12 model essentially in name only, but change its function to drive the BBSS and test QOSEMS.
To do this, Oli changed the h1susbbss.mdl file to:
- use h1suslo12's dcuid=188
- remove all IPC senders
- reduce the number of DAC channels, only using those freed up by the h1susbs changes
This approach means the H1.ipc and testpoint.par files are unchanged. The H1SUSLO12.txt filterfile and safe.snap files are substantially changed, but these had not been commissioned. The H1SUSLO12.ini file was also essentially rewritten for BBSS with the exception of some FEC channels.
There were no issues with rebuilding and installing the new h1susbs and h1suslo12 models. The old versions were stopped before the new ones were started because we are swapping DAC drives between these models.
DAQ Restart
The DAQ was restarted for the model changes. There were no issues found.
CDS Overview
The h1suslo12 entry on the CDS Overview has a new color/label to denote its current usage as the BBSS model. Also note the removal of some IPC senders from h1susbs means we have continuous IPC receive errors on the h1susmc2 and h1seiproc models.
