Experimental Physics and
Industrial Control System

Here is my understanding of what is softIOC and what is soft record:

1. softIOC: any IOC (application/instance) running on Linux or Darwin is a softIOC since each softIOC is an independent process and multiple softIOCs can be running on the same physical machine. On the other hand, only one IOC can be running on vxWorks or RTEMS so that I would say IOC running on vxWorks or RTEMS is not a typical sofIOC. A softIOC can control real hardware.

2. soft record: any record not associated with real hardware is a soft record. The DTYP field of a soft record is "Soft Channel" (default for DTYP), "Raw Soft Channel", or "Async Soft Channel".  

What are your definitions? 

Thanks,
