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. William Lu Jefferson Lab -- Weiwei Lu 757-269-7476 [email protected]
