arm initial alignment work

I installed the following IPC links:

ASC to ISCEX:    PZT1X_PIT PZT2X_PIT, PZT1X_YAW PZT2X_YAW  (all four are being received)
ASC to ISCEY:    PZT1Y_PIT PZT2Y_PIT, PZT1Y_YAW PZT2Y_YAW  (all four are being received)
ASC to SUSTMSX:  TMSX_PIT, TMSX_YAW  (not being received yet)
ASC to SUSTMSY:  TMSY_PIT, TMSY_YAW  (not being received yet)

(links for ASC to ETMs and ITMs were already installed.)


checked in
h1asc.mdl:  SVN revision 6769
h1iscex.mdl: SVN revision 6770
h1iscey.mdl: SVN revision 6770

We are still getting some IPC errors.

I've completed the install of the new IPC communication between the ASC front-end model and the TMS and HTTS models for green / REFL alignment control. This required 
- (as Stefan mentions above) Adding RFM IPC parts to the ASC model to send to the end-station SUS computers,
H1:ASC_TMSX_PIT_SUSTMSX
H1:ASC_TMSX_YAW_SUSTMSX
H1:ASC_TMSY_PIT_SUSTMSY
H1:ASC_TMSY_YAW_SUSTMSY
- (as Stefan *didn't* mention above) Adding SHMEM IPC parts to the ASC model to send to the HTTS core on the same front-end
H1:ASC_RM1_PIT_SUSHTTS
H1:ASC_RM1_YAW_SUSHTTS
H1:ASC_RM2_PIT_SUSHTTS
H1:ASC_RM2_YAW_SUSHTTS
- Modifying the ASC and OAF IOP model parameters to turn on the RFM capability (Set "rfm_dma=1")
- Installing all of the above mentioned channel into the respective receiver models, and hooking them up to the already-present place holders in the ISC input bus creator,
h1sustmsx --> H1:ASC_TMSX_PIT_SUSTMSX, H1:ASC_TMSX_YAW_SUSTMSX
h1sustmsy --> H1:ASC_TMSY_PIT_SUSTMSY, H1:ASC_TMSY_YAW_SUSTMSY
h1sushtts --> H1:ASC_RM1_PIT_SUSHTTS, H1:ASC_RM1_YAW_SUSHTTS, H1:ASC_RM2_PIT_SUSHTTS, H1:ASC_RM2_YAW_SUSHTTS
- Re-compiling, Re-installing, Re-starting, and Re-storing all of the following models:
h1iopasc0
h1iopoaf0
h1asc
h1sustmsx
h1sustmsy
h1sushtts
All of the modified models mentioned above have been committed to the userapps repository.

Taking down H1 SUS TMSX naturally trips the watchdog on HPI and ISI ETMX, so Hugh and I made sure to ramp down all offsets before getting started. After restoring, Hugh has brought up HPI ETMX and ISI ETMX, and I've restored the alignment of both SUS ETMX and SUS TMSX. No one is using the RMs just yet, so they have not been restored -- and indeed, they do not yet have a good safe.snap, so they will need a complete restore from scratch. Bummer.
