Timo,
I'm very interested in learning how you do this. Do you have a separate server calculating the optics parameters and sticking them in the EPICS records? Or do you build the calculations into the records of individual devices?

My question is this:  To what extent are the physics parameters part of the controls? 
Should there be channels like "Separator:BeamMass," for example?
My feeling is that the beam, as it were, should be part of the control system from the beginning, but I don't have much to back this up.
What do you think?
 
To me and my colleagues (most of them, at least) here this has never even been a question but an obvious thing.
We have (in SLS) all kinds of physics parameters as epics channels (tune, chromacity, etc. for the synchrotron
and, for instance photon energy and polarization for the beamlines.) This brings so many advantages
that I cannot even count...
Of course, you then have to have people in controls that look after and understand these issues. This
in turn makes the communication between different groups much easier. Bob also pointed this out.

So, my 2 cents go for a big yes.

best regards,

Timo
