Subject: Process aSub record on arrival of data

Hi folks,

I have 2 aSub records: Tx on IOC  A and Rx on IOC B.
IOC A and B are on different machines on my network.

I want Tx to send an array to Rx over CA (or PVA). Once the data arrives is there a stock method to trigger Rx to process? IIUC, using the CPP attribute in Tx.OUTA will not cause the Rx to process since these records are on different IOC's. I'm using another OUT link in Tx to write to Rx.PROC.

Is that the most efficient way to do this?

I know there's history to this and the genSub record at Gemini has been customized to process on the arrival of data to certain input fields. I'm trying to accomplish that in an aSub.

Example below
EPICS 7 latest build from github.
Linux Rocky 8

Thanks!

===========IOC A==============
 record(aSub,"test:TX") {
       field(SNAM,"transmitter")
       field(NOVA, "5")
       field(OUTA, "test:RX.A NPP NMS")
       field(OUTB, "test:RX.PROC NPP NMS")
   }

===========IOC B==============
record(aSub,"test:RX") {
      field(NOA, "5")
}
