The DC readout of the PSL-FSS RFPD cable was connected to the 7th channel of the PSL-FSS ADC. The h1lsc model was changed to remove this channel and the h1pslfss model was changed to add this channel (channel name was not changed in the transition).

In detail,

LSC model PSL top-named part, model file is lsc/common/models/lscpsl.mdl. This had three parts:

filter-module-with-control (all inputs grounded) for RFPD which was removed (moved to h1pslfss)

filter-module-with-control (all inputs grounded) POWER_SCALE which has extensive LSC links and (via IPC) ASC links too. We left this unchanged.

epics-input part (input grounded) POWER_REQUEST which was not used by the model nor any MEDM other than tam.adl. Kiwamu gave permission to remove this.

PSL FSS model, file psl/common/models/pslfss.mdl modified to connect the 7th ADC input to a new standard IIR filter called RFPF_DC

Bottom line: tthe filter module name is still H1:PSL-FSS_RFPD_DC, but is now hosted from h1pslfss and not h1lsc and is a standard IIR filter sans controls.
