The dbpf does not work. It gives the error message as below:
epics> dbpf LS450PS:asyn.AOUT abc
filename="../dbTest.c" line number=295
putFields are disabled - dbPutField error
Thanks,

Can you change the fields locally from the ioc shell (using "dbpf")?
If yes, is Access Security enabled? Do you have write access rights?
("cainfo" on the client machine will tell you.)

I am having problems with channel access writes on asyn record's
writable fields such AOUT and PORT. I created the following asyn
tcp/ip port and the asyn record:
In a startup iocsh script:
drvAsynIPPortConfigure("sockserv","127.0.0.1:9099",0,0,0)
The asyn record:
record(asyn, LS450PS:asyn) {
field(DTYP, "asynRecordDevice")
field(PORT, "sockserv")
field(ADDR,"0")
}
After the record has been loaded to the ioc, I cannot write the AOUT
or PORT fields of the record through channel access. When I caput on
those fields, I got the error messages like the following:
>caput LS450PS:asyn.AOUT "abc"
Old : LS450PS:asyn.AOUT
CA.Client.Diagnostic..............................................
Message: "Could not perform a database value put for that channel"
Severity: "Warning" Context: "detected by:
devl17.acc.jlab.org:5064 for: LS450PS:asyn - with request
chan=LS450PS:asyn.AOUT op=1 data type=DBR_STRING count=1"
..................................................................
New : LS450PS:asyn.AOUT
What is the problem? Any help would be gratefully appreciated.
