Summary of new features:
- Blends and sensor correction will be split into two separate nodes.
- This cleans everything up and helps simplify how/when the SC can be changed.
- We are currently not changing the HAM blends so they don't get a BLND node.
- Most of the states and edges are now auto-generated from a single configuration file.
- The user can simply change the name of configurations, filter banks, filters, etc. in the file and then load the node. No editing of code necessary. This is very similar to how the rest of the SEI Guardian code is written. I tried to stay consistent at least.
- Allows for two different ways to switch sensor correction.
- We do it slightly different compared to how LLO wants to do it, so I wrote both in.
Longer explanation of work:
All of the old SEI nodes that ended in *_CONF have been destroyed (a total of 15), and have been replaced with one or two other configuration nodes. Every HAM and BSC stage now has a sensor correction node (15 in total, name ends in *_SC), and each BSC stage also has a blend node (10 in total, name ends in *_BLND). Back in September, I tested the SC code on ITMX (alog38588) in preparation for this new setup but ran out of a time and a window to implement it. This week was looking to be perfect time to get us into our new configuration setup. The old setup was a product of JIm and I figuring out how to run the blends and sensor correction together to move the IFO into different seismic configurations based on what the environment was doing. We seem to have settled on a good way to do it after O2, but the old nodes were getting too complicated. A rewrite was necessary.
Breaking each CONF node up into separate blend and sensor correction nodes made them a bit more straightforward. I also changed it to read a large configuration file to obtain and create all of the necessary states and transitions. This is how much of the other SEI Guardian code is, and I felt that it helped the SEI team to make changes a bit easier. Plus, I've found that staying consistent with code within subsystems is generally helpful.
I tested the new nodes on ETMY first and checked with Jim before pushing it through to the rest of the chambers. I still have a bit more name changing and a few settings to change tomorrow, but all of the nodes seem to be running well.
Still left to do this week:
- Adapt the SEI_CONF manager to work with the new nodes
- Write an INIT state
- Clean up code and add more comments
- Update all of the medm screens that have the old nodes
- Possibly rework the Guardian Overview screen, if time permits
I've attached a shot of the current overview for your viewing pleasure.
Since the SEI_CONF manager is not able to communicate with these conf nodes yet, for tonight we cannot use the "LARGE EQ" button, or use it to turn off BRS corrected sensor correction. The BRS is not a big deal at the moment since those paths are all turned off.
