Another round of PEM model changes and DAQ restart

Robert, Dave:

Thursday 12th February 2026

h1pemex was changed, the newly installed AMON subsystem which reads the current to ground signal now drives the 4th channel of the 20bit-DAC via the GDS_3/DACOUTF_3 filter module chain.

h1pemey was modified to fix a typo I had made to the DACOUTF_3 filtermodules, it was missing the underscore.

Both models were restarted at 15:55, followed by a DAQ restart at 16:01-16:06

I created MEDMs for the new DAC drive system. I'll work with Ryan S on integrating this with his "GDS DAC DRIVE" screen, currently I've added buttons to the bottom of Ryan's MEDM to open mine.

I made a slight change to h1pemex to reposition output ports and connect them via goto-tags for the mainsmon channels which are sent via long-range dolphin to h1oaf.

I restarted h1pemex at 08:47 (no DAQ restart needed) and verified the IPC was still good.
