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.
