Hi,

you can use the redirection mechanism of streamdevice.
Just configure your ai1 record to use stream as DTYP and the protocol as input:

record (ai "ai1") {
    field (DTYP, "stream")
    field (INP,  "@myDev.proto getMsg dev1")
    field (SCAN, "I/O Intr")
 }


Your protocol would look like this:
getMsg {
  in "*05CC%d#*05DD%(ai2.VAL)d#*05EE%(ai3.VAL)#"
}

I'm not sure though if one should define the length for the format converters here?

Best regards,
Florian

hi, all:

   If the device send a string to IOC automaticlly, the data is like "*05CC1234#*05DD5678#*05EE1345#". I have three ai records as ai1,ai2,ai3.
I want to get "1234" of "*05CC1234#" to ai1, "5678" of "*05DD5678#" to ai2, "1345" of "*05EE1345#" to ai3, how can I implement it?
   thanks a lot in advance.


Best regards
