Experimental Physics and
Industrial Control System

Hello All,

 

We are in the design phase of a new accelerator project which will be built in the frame of the so-called  “broader approach of the ITER project”. The goal of this accelerator (Eveda) is the validation of the solutions for the future high power accelerator IFMIF (International Fusion Materials Irradiation Facility).

 

The control system will be based (of course) on Epics with VME IOCs. The question is which RT OS to use? We are users of VxWorks for a very long time for several projects and we were always very happy with this system. It’s expensive and we are no more privileged customers of VxWorks but it’s for sure a great product. As we saw some interest for RTEMS in the community, we did complete tests with Epics including the port of drivers for our favourite modules. All this was satisfactory, so  we are really now at a cornerstone… and we need some feedback of facilities using RTEMS. What are the advantages or drawbacks based on your experience? Reliability? Off-the-shelf availability of drivers (for PMC modules for example)? availability of great features of VxWorks like the global symbol table or the interactive functions call? Etc …

 

Many thanks,

Jean-François
