Hello,

I'm trying to use subArray record type to display each array element at
index 0 .. n (n == 10; my case) in a separate PV.

record(bi, "$(DEVICE)ACQUIRE") {
	field(SCAN, "I/O Intr")
	field(DTYP, "asynUInt32Digital")
	field(FLNK, "$(DEVICE)MONITOR PP")
	field(INP, "@asynMask($(PORT), 200, 0x1, 1.0)")
}

record(waveform, "$(DEVICE)MONITOR") {
	field(DESC, "A B C D X Y Q SUM CX CY")
	field(DTYP, "asynInt32ArrayIn")
	field(FLNK, "$(DEVICE)A PP")
	field(INP, "@asyn($(PORT), 200)")
	field(NELM, "16")
	field(FTVL, "LONG")
}

record(subArray, "$(DEVICE)A") {
	field(INP, "$(DEVICE)MONITOR")
	field(INDX, "0")
	#field(MALM, "16")
	field(MALM, "1")
	field(NELM, "1")
	field(FTVL, "LONG")
	field(FLNK, "$(DEVICE)B PP")
}

record(subArray, "$(DEVICE)B") {
	field(INP, "$(DEVICE)MONITOR")
	field(INDX, "1")
	#field(MALM, "16")
	field(MALM, "1")
	field(NELM, "1")
	field(FTVL, "LONG")
	field(FLNK, "$(DEVICE)C PP")
}

Above are the records that I use. But the record A and B do not work as
expected - A and B both display MONITOR element at index 0. See below:

Now, if remove all the lines with:
	field(MALM, "1")
	field(NELM, "1")
in records A and B, and add this instead:
	field(MALM, "16")

records A and B work as expected, but they are 16 fields long - I would
like to see them 1 element long as the really are (one 32 bit integer
value).

How can one implement single element PV in subArray record?

Thank you,
