Experimental Physics and Industrial Control System
I have a periodic scanned PV which I occasionally set. However, when I set it, I can’t read the updated value until the periodic scan happens. I would like the PV value to update as soon as it’s set. I thought that was what was supposed to happen with FLNK but it doesn’t seem to.
My db has:
record (ai, "$(P):current1")
{
field (DTYP, "stream")
field (INP, "@thorlab.proto getcurrentch(1) $(BUS)")
field (SCAN, "10 second")
}
record (ao, "$(P):setcurrent1")
{
field (DTYP, "stream")
field (OUT, "@thorlab.proto setcurrentch(1) $(BUS)")
field (FLNK, "$(P):current1.PROC")
field (SCAN, "Passive")
}
"caput setcurrent1 10" works but it takes whatever is left of the 10 second scan period before current1 changes.
“caput current1.PROC 1” immediately updates the value in current1.
I tried field (FLNK, "$(P):current1”) but that doesn’t process either.
What’s the trick for getting a periodic scan PV to process within a forward link? Or is there some other way I’m supposed to do this?
Thanks.
