Hi Dehong,

> Can one EPICS record listen to more than one event?  If yes, how could set it up?

Do you mean can one record be processed on different events?  If that is what you mean, then you could FLNK to the record from both event records.  For instance, if I have 2 EVR event records (for EVR card 0), I could FLNK to the same record from both of them like this:

record(event, "Test:Event1") {
  field(DTYP, "MRF Event Receiver")
  field(INP, "#C0 S1 @")
  field(SCAN, "I/O Intr")
  field(VAL, "1")
  field(FLNK, "Test:RecordToProcessOnEvent1or2")
}
record(event, "Test:Event2") {
  field(DTYP, "MRF Event Receiver")
  field(INP, "#C0 S2 @")
  field(SCAN, "I/O Intr")
  field(VAL, "2")
  field(FLNK, "Test:RecordToProcessOnEvent1or2")
}
record(ai, "Test:RecordToProcessOnEvent1or2") {
  field(SCAN, "Passive")
...other ai fields here...
}
