Hi:

As mentioned, Channel Access doesn't tell you what fields a record might
have. You have to parse the DBD file that your IOC loaded.

> Yes, CSS includes PVTree which is similar.
The CSS PV Tree, 
http://sourceforge.net/apps/trac/cs-studio/wiki/EPICSPVTree, uses Channel
Access to read .RTYP, then uses a configurable table to read more fields
depending on the record type, for example INPA, INPB, INPC, ... for calc
records, and tries to figure out if those in turn contain what looks like
another record name, which it then reads recursively.

In addition we have a "PV Fields" tool for CSS, see
http://sourceforge.net/apps/trac/cs-studio/wiki/PVFieldsViewer ,
that displays all the configured fields of a record,
Value in the original DB file as well as current value,
based on IRMIS-type data in the RDB.

Thanks,
Kay
