Dear All, 

I just make my plan (and specification) for the future. 
I would like to do adding:
- adding configuration tool to CDI (V5.0, current is 4.2)
  it has affect to the device/driver configuration tools
  of Epics  (this is comeing soon)
- adding dynamic (run time) changeing of INP/OUT field,
  DTYP field at least of the filed-bus devices such as
  CAN,H1,Profi,Sedac,Classic - the planned platform:
  Epics Rel 3.13.xx and VxWorks 3.13 , CDI V5.0 
  (long term plan !)
- I don't want to braek any planned work of Epics device/
  driver configuration tool.

Some idea :
----------
(useing my phantasy or some idea of somebody else,
mainly Marty and Jeff and the reactions of my RAWH RAWL
proposal)

(I'm thinking of 'field-bus' devices maybe this ide 
doesn't fit to the others :) )

- a device support module is software mirror of a 'CAN' controller.
- a (new) 'module' record is a software mirror of a 'CAN' module 
 (e.g. Weitmuller di module on CAN) 
 ( the RAWH and RAWL values can be stored here )
- The 'channel' record (e.g. ai) has a pointer to the correspondance
'module' record.  (A new link field ? )

Some techical issue ;

Is there a function :
- The input is a 'record name' the output is 'the record address' ?
- The input is a 'record address' the output is the record type ?

I need the configurable information on the device level.
========================================================

Please give any comment !!!
