WP13096 Add missing h1lsc ALS DIFF PLL channel to DAQ

Jonathan, Erik, EJ, Dave:

The missing H1:ALS-C_DIFF_PLL_CTRL_OUT_DQ channel was added to the h1lsc model's DAQ Block.

We initially just restarted h1lsc, but this caused a DAC error in h1ioplsc0 (similar to h1ascimc and h1iopasc0) which meant we had to restart all the models on h1lsc0.

A DAQ restart was required.

WP13078 Add pending slow controls and h1sush6 to DAQ

WP13094 Add JAC CAM EPICS and CHETA slow chans to DAQ

DAQ RESTART

Jonathan, Erik, EJ, Dave:

A new H1EDC.ini was created with the following changes:

H1EPICS_DIGVIDEO.ini Regenerated with JAC CAM (cam38) added (+25)

H1EPICS_ECATTCSCS.ini Added CHETA laser pwr chans (+2)

H1EPICS_ECATAUXCS.ini Added C_PZT_SHUTTER chans (+11)

H1EPICS_FEC.ini Added h1sush6 models (+97)

H1EPICS_SDF.ini Added h1sush6 models (+160)

H1EPICS_DAQ.ini Added h1sush6 models (+32)

total +327. Num chans increased from 60582 to 60909.

Erik ran puppet to officially add all the new h1sush6 models to the system (I had done some hand-editing last week). He also determined the DAQ time slot h1sush6 should used.

Jonathan got the DAQ ready for the new front end and models. He also plugged the DAQ ethernet cable into the back of h1sush6 (the Dolphin cable remains unplugged for now).

We rebooted h1sush6 to get the DAQ sending started.

Jonathan then restarted the DAQ, starting with the 0-leg. I restarted the EDC at this time.

A second 0-leg restart was required to complete the configuration.

When this was stable, the 1-leg was restarted with no issues. 

We saw two spontaneous restarts of FW0 around this time, which had been seen before. At time of writing, FW0 has been up for 90 minutes.

Updates and Cleanup

Dave:

I regenerated the CDS Overview, changing h1sush6 from NO_DAQ to NOMINAL

I had to hand edit the python code generating the H1EPICS_[FEC,SDF].ini to add the new models even when they were not yet added to the DAQ, so we only needed to restart the DAQ once.

I updated DAQSTAT and CDS_HW_STAT to expect the new FECs, Models, ADCs, DACs.

Guardian Node Loading Modified Source Code.

Ryan S:

Recent changes to lscparams.py (last modified 18:43 16mar2026) and ISC_library.py (last modified 16:55 10mar2026) meant that 22 guardian nodes were pending reloading of these files.

Ryan verified that the changes made to the source code was orthogonal to the snipets used by these nodes and reloaded to the code into them to clear up the GRD CFC flags.
