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
