Summary: Ryan and I updated the JAC and IMC ASC models. We installed JM3 yesterday and so now the IMC cannot use the PSL PZT mirror as an alignment actuator. I have committed the changes to the svn but erik and dave will do some checks tomorrow before they commit to the revision locked version of the model and restart the DAQ. So changes are not 'live' yet.
The edits were made to h1ascimc.mdl which has top level blocks for IMC and JAC.
The JAC top level model sends signals directly to the PSL PZT mirror and these degrees of freedom are swapped as the PSL PZT basis P and Y are switched before input to the JAC due to the HAM1 input periscope.
I took out the feedback paths for PZT_P and PZT_Y that come out of the IMC block. The picture shows the old config and I have highlighted what I removed.
At the top level, IMC no longer sends signals to the PZT but instead to JM3. On the top level diagram, the signal JM3_P is sent via PCI cards to the channel "H1ASC-JM3_YAW_SUSHTTS" as pitch in the JAC basis is yaw in the IMC basis due to the HAM1 output periscope. The picture shows the old config and I have highlighted what I swapped.
The signal JM3_Y is sent via PCI cards to the channel "H1ASC-JM3_PIT_SUSHTTS" as yaw in the JAC basis is pitch in the IMC basis due to the HAM1 output periscope.
Within the IMC top names block I removed the output channels for the PZT from the WFS feedback path, we already had paths to feedback to JM3 within this path. The picture shows the new config.
I removed the PZT locking path from the LCKIN block and replaced it with one for JM3. The picture shows the new config. I am not sure we ever use this path (which is for dither asc control of the IMC) in the first place so maybe this was unneccessary.
I also removed the channels H1:IMC-PZT_YAW_OUT and H1:IMC-PZT_PIT_OUT from the DAQ channel list for the IMC model.

This morning I rebuilt the model again before it was restarted to add back in the IMC-PZT_PIT_OUT_DQ and H1:IMC-PZT_YAW_OUT_DQ channels in the top level of h1ascimc so as to avoid removing these channels from the GDS broadcast channel list.
Unfortunately this change did not get propagated to the live model today (it was not built with the rev-locked tag). This caused some confusion when the model + DAQ restart happened ( alog #89196). I had forgotten to SDF the PZT sliders for IMC-PZT_OUT and so this mis-aligned the beam to the JAC. Keita brought this back by altering the IMC sliders and we were able to continue with optics work in HAM1.
On the CDS side, none of my changes from today or yesterday have been uploaded to the 'rev-locked version of the model so everything was restarted with the old model config from yesterday morning. We will aim to restart with model changes to h1ascimc (that I made last night and this morning) at sometime Monday morning.
