New ASC model installed, SDF updated

New ASC model was installed.

SDF showed more than 6000 channels that are not available in the frame. These were either deleted in this model uptate (entire Initial Alignment System, some Alignment Dither System signals etc.) or obsolete channels from long time ago (e.g. all ASC-ALS signals that were moved to ALS model a long time ago).

Betsy made a new snapshot and we confired everything in SDF for new channels.

Note that the ASC MEDM screen is NOT updated. Functionality of the new model is exactly the same as before (new things introduced at LLO are terminated at the top level at LHO except new dither system).

Just after I wrote the above entry, I was looking at the old model file again and caught something that I didn't yesterday: The output matrix signal order was funny (OM1, OM2, TMSX, TMSY, then OM3).

I went back to the new model, and unfortunately it turned out that the new model from LLO "fixed" the funny order by reshuffling TMSX, TMSY and OM3 signals in the matrix. What used to be the matrix elements for TMSX, TMSY, OM3 are now for OM3, TMSX, TMSY, i.e. the TMSX signal is now sent to OM3, and TMSY signal to TMSX.

Since the guardian is not touching this output matrix, we decided to just manually change the output matrix (not the model, but the epics values for corresponding matrix elements). After this change, new output matrix MEDM screen was pulled from svn and everything was fine.

New ASC master medm was also pulled from svn and it looks OK.

I updated the input matrix MEDM, but everything was white on that one so I put the old one back.

And, SDF has been updated to capture the new matrix elements in the ascsafe.snap
