H2SUSTMSY fixed

Yesterday, we managed to fix the model. Renamed the DAC_x names so the first DAC name starts at '0' (DAC_0 and DAC_1), and also renamed the OSEM_OUT to COIL_OUT to be consistent with the quad models.

 

I am not sure if I fixed it the 'proper' way, but I changed coil output names in the TMTS_MASTER.mdl. I also used all capitals for the _IN and _OUT names. Then in the H2SUSTMSY.mdl I changed the names of the DAC_x blocks (as mentionedin the T080135-v4 (page 42), but left the card_num to 2 and 3 respectivily. I copied the models by changing the name to 'name'_24oct2011, but don't know if or how to upload them to svn or not.

 

We recompiled and installed the front-end, and all seemed to work. We check the output by setting an offset on one of the output filters (F3 in our case). There is a nice feature, that on the EPICS screen (SUS_CUST_TMTS_OVERVIEW.adl) the last value (just before the grey button to H2SUSTMSY_DAC_MONITOR_0.adl) is 100. But when looking on the H2SUSTMSY_DAC_MONITOR_0.adl (which is the output of the TMS model) the DAC0 OUT value is 99, and further looking on H2IOPSUSB6_DAC_MONITOR_0.adl (which is the IOP model which actually talks to the DAC) DAC2 OUT value is 101!? Go figure.

The original entry seemed to be quit cryptic, so here is some more info.

In h2sustmsy.mdl there is a TMSY block with all the standard top level components in it (ADC, DAC etc). The TMSY block has a little arrow in the bottom right corner.

I modified the DAC_x/y to DAC_0/1 in the top level of the model. After recompiling all seemed to work fine.

In addition I changed the names of the outports.

Follow this link gives me: TMTS_MASTER.

-> open (double click) TMTS, and I renamed the outports from _OSEM_F3_Out to _COIL_F3_OUT etc. It turns out I didn't change the _In to _IN.

I didn't break the link, I modified the TMST_MASTER library part (didn't know how to break the link).


--> checking the block properties of the M1 gives a description of 'SIXOSEMSTAGE_FACE_MASTER' which I presume is the name of the library part. When I open it (via the open link), I get 'SIXOSEM_F_STAGE_MASTER with a description of 'SIXOSEMSTAGE_FACE_MASTER'. I don't think this is crucial but very confusing.

I presume it is still here on the compile server at LHO only. Will see to get it uploaded to svn.
