Subject: PMC and IMC locked again, some MEDM maintenance 

Wrote the script. It currently lives at /users/milind/NonlinearControl/milind/unstick/unstick.py. Also pushed it to the repo here. It does the following:

  1. When run as python unstick.py c1aux (for instance) from the terminal, it parses the autoBurt.req file at /cvs/cds/caltech/target/c1aux/autoBurt.req and obtains the channels.
  2. Iterates through the channels and changes it to "some value"
    1. For channels corresponding to buttons on MEDM screen (Enable/Disable etc.) toggles between 0 and 1
    2. For channels corresponding to continuous values (such as say exposure time or the like) changes to abs(1+current_value)
  3. Resets to original value and then moves to the next channel

I tried print statements instead of actually writing to the channels as Gautam asked me to do that with supervision. Is this good enough?

a useful piece of code that we should ask one of this summer's SURFs to write:

  1. read in a BURT .req file which is usually used to make the autosnap / restore.
  2. change ALL of the values to some value (slightly different from its current value)
  3. restore it to its current value

this will solve the sticky slider problem and do it in a systematic way. We can run it from the command line: e.g. 'unsticky.py c1psl c1ioo c1lsc'

Aaron complained to me earlier that the PMC could not be locked. Turned out to be a classic sticky slider problem,
