LSC and OMC models changes

Kiwamu, Jim, Dave:

New h1lsc and h1omc models were created and installed this morning. The DAQ was then restarted.

The change was to expand a single filter module to two in series (providing the potential for 20 filters) for the DARM, MICH, PRCL and SRCL paths.

models were chaged at 11:11 PST and the DAQ at 11:13 PST.

This change is the one we requested through the ECR E1600030-v1. As reported by Dave above, we increased the number of available filter modules in DARM, PRCL, SRCL and MICH by inserting a filter in series for each of them.

The attached screenshots show how the simulink models now look like.


The changes and new modules are highlighted by circles and arrows in the screenshots. As shown, the DARM filter module is split into DARM1 and DARM2. DARM1 still has the triggered filters while DARM2 does not. Additionally, in order to save the important channels DARM_IN1 and DARM_OUT, we added two test points with their names. The same change was applied to PRCL, SRCL and MICH. This change will not impact on the online calibration, calibration lines or hardware injection.

The last attachment is a screenshot of the new medm screen.

The models and screens are checked into SVN.

P.S. I have updated all the ISC-related guardian codes so that they can handle this new filter situation. I did not get a chance to test them. So please watch out for some bugs in the guardians
