Feedback loops which use SLCNET do not support correlation plots.
This includes FB31 for FFTB. To find a list of feedback loops with SLCNET
communications, go to the kistest help, on the CALB/DIAG panel from the
fast feedback system panel.
...
Regarding the FFTB FB31 energy feedback loop:
It does not support correlation plots. The reason is a conflict
with the communications software. This loop was originally intended to
have
a kisnet link from CB00 to FB31, but the link was flaky. So we put in
an alternate database to use SLCNET communications. We discovered a few
years
ago that the feedback SLCNET communications software, as written, cannot
co-exist with
correlation plots. There was a cater, and it was solved. I remember
discussing this
at the time, probably with Mike Stanek; I think we had a choice between:
...
I think we chose option 3. I put a comment into the kistest help that
crr fails for this loop
when SLCNET is enabled. If anyone would like to vote on a different option,
feel free. Please let me know if anyone would like to talk more about
this.
