J. Kissel I've modified all HAM SUS front end code to receive dither alignment signals from the ASC front end. Currently, however, the sending channels have dummy constants as input at the top level of the h1asc model, because there's work internal to the ASC library block that needs doing. I leave the ASC model changes in the very capable hands of the ISC team. Thankfully, recovery was easy from these changes went much more smoothly than Monday's. We had no guardian machine failures or IOP DAC FIFO errors, and the MC REFL path stayed put. As such, once we went back to laser hazard, the IMC popped right back into business. Obviously, everything went smoothly because plenty of relevant parties were here on site. #sarcasm I have not yet begun to make the necessary MEDM screen modifications (which is how I was able to get through the changes so fast). I'll begin doing so in a bit and post shots later. I also have not committed any of the changed library parts mentioned below, because I'm not sure yet how LLO would like to roll out these past few days of changes. However, all top level models have been committed, since they don't affect LLO. Details ----------------- Of the list of front end models mentioned this morning, I got through h1asc SUS top-level models: h1susprm h1suspr2 h1suspr3 h1sussrm h1sussr2 h1sussr3 h1susmc1 h1susmc2 h1susmc3 SUS library parts: FOUROSEM_STAGE_MASTER FOUROSEM_STAGE_MASTER_OPLEV SIXOSEM_T_STAGE_MASTER HLTS_MASTER HSTS_MASTER MC_MASTER Though the IMC models do not receive dither, they use the HSTS_MASTER and MC_MASTER parts, so the dither inputs had to be terminated at the top level. Minor mod, but still a mod. I've also added place-holder IPC receivers to the top level of all BS, and all QUAD models, but they're terminated at the top level, since I've not yet made changes to the QUAD or BSFM library parts. I attach lots of screenshots of the affected simulink models, to show how I've implemented the path.
