It seems to me that the problem pertains to the asyn library binary I was using. It may not have been built correctly. Asyn R4-10 should be fine, since no similar cases can be found in tech-talk.

Thanks,
William

I finally got it working. The problem turned out to be that there is something wrong with the asyn library my code was linking to. After I linked my code to a different asyn library (R4-13), the asynRecord is working. Thank you very much for your help. I really appreciate it.

Note that DSET=(nil) and RSET=(nil). That is wrong.

It looks to me like the record was not initialized correctly.  Did you
get errors in iocInit?

Here is what I got. By the way, I am using asyn version R4-10.

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"

What is the problem? Any help would be gratefully appreciated.
