Run_Control interface
Data to be downloaded must be ready in before run start, ideally SVT has been fully configured and downloaded after power up.
Run_Control must have a way to check (force?) this
Run_Control must start SVT monitor process(es)
After some data tacking (1 min ?) Run_Control must query SVT for a check on beam position.
If beam position has to be adjusted, data taking has to continue to give feedback. If SVT parameters needs to be changed run has to stop/restart with a different number (does it?).
SVT severe errors are handled via CDF Error/Recovery/Start protocol
No need for software message passing during run.
At run end Run_Control signals SVT monitor process(es) to send statistics for proper storage (DB ? EndRun record ?)
