Dear Andrew,
thank you for your reply and help, following your guide, the problem mentioned
in the last mail has been resolved. now, I come across a new problem as below:

dbPutField error
I guess something is wrong when the record "R4IBT04:CISet" calls device support
write_ao which calls driver support, I don't know how to solve it. thank you
again!

    There is a problem while downloading an "ao" record which is used for a

This error message is generated by the ao record support when the device
support's init_record() routine returns any value other than 0 or 2; that's
all I can tell you based on your report. You'll have to take a look at
the "PSC" device support for the ao record and work out why it's returning
something different, what it means and how to fix it.
