Re: [EXTERNAL] Does every DB record need to produce a PV?

["Hartman, Steven via Tech-talk" <tech-talk at aps.anl.gov>]

From my perspective, an EPICS IOC with ~2000 PVs lacking descriptions, for a device without a Programmer’s Manual, is unmanageable.

Perhaps. But no more unmanageable than receiving a custom CA or PVA server application implementing similar functionality as that IOC, also without proper documentation.  

Actually, the IOC may well be preferable. At least with the IOC, much of the functionality is well defined: scan logic, interface to device support, internal / external interfaces to other PVs, alarm configuration, alarm status and severity, high/low set point limits, ability to query input and output configuration, error reporting, time stamps, and lots of other capabilities that may or may not be implemented in the non-IOC implementation. Plus it is using well tested code with resources for support if needed.
