Tip Tilts Model Change

[Jeff Dave Arnaud]


After Keita reported he couldn't access to tip tilts medm screen to damp the suspension (which hasn't been updated yet), I looked at RM1_M1_OSEMINF signals to see if I could damp it from the command line. Although, the readback was zero even though we were seeing numbers out of the ADC, which directed us to a model issue. Some modifications from last week would prevent the model to compile properly so we undid some of the changes and fixed some other issues. After restarting the models after the changes, the channels were back alive. Last thing to do is to resurrect the medm.

Modifications made on

**h1sushtts.mdl** (1st screenshot)

1) Grounded the calibrated ISI signals outputs from HTTS

2) Linked the ISI signals directly from the IPC to OM1/2/3, instead of the ones going out of HTTS

3) Changed ADC7 to ADC0

4) Modified the channels to match with 3)

**HSSS_MASTER.mdl** (2nd screenshot)

1) M1/ISIINF CdsEpicsOuput banks changed to CdsFilt banks
