Subject: Reset integral pv and store it

Hi all,

I have a PV that is an integral over the day. I would like at the end of the day(certain timestamp) to store it to the DB (maybe in another PV) and after that reset the integral.

I would also like that if epics restarts the intergal will initiate with the most recent value in the DB.

My DB is with mysql with the CSS archive engine.

my current integral PV:

record(calc, "$(user):DLI"){
    field(DESC, " Daily light Integral (mol.m-2.day-1)")

    field(INPA, "$(user):Lum1")
    field(INPB, "$(user):DLI")
    field(CALC, "A*1e-6+B")

    field(SCAN, "1 second")
    field(EGU, "DLI")
    #field(PREC, "6")
    #field(ADEL, "10")

    field(LOPR, "0")
    field(HOPR, "1000")    #High Operating Range
}

Thanks a lot,
MiguelB
