Hi Armando,
I'm afraid I haven't got a ready-baked solution for this one. However, I have always thought the DLS "positioner" could be implemented quite neatly as a state machine in SNL...?
Cheers, Ulrik
Hello all,
I am trying to find some support module that would allow to store some values and apply these to at least 1 PV from an enum. The idea is to allow end users to defining pre-selected values and apply these to a configured PV or group of PVs on demand. Ideally,
something independent of the motor record that can be applied to any existing PV.
As an example, let's imagine a motor-controlled multi-filter with specific positions for each one (e.g. Cu=0, Si=50, Pt=80): the user can drive it to any value within range using a motor record, but also can comfortably select one the positions and command
the motion to any of the specific values -- in the example, when selecting "Pt" the motor is commanded to value=80.
FYI, at Diamond we do have a similar one called simply "positioner", but it's quite complex and old for proper maintainability, and thus I am looking for a substitute.
Does anyone know about or have already implemented EPICS support for something like that? Please let me know, any help would be much appreciated.
Many thanks,
Armando Pueyos
