RE: how NOT to update the record

["Mooney, Tim M." <mooney@aps.anl.gov>]

Hi Tasaddaq,

One way to do that is like this:

record (calcout, "c"){

field(SCAN, "1 second")

field(INPA, "c")

field(INPB,"b")

field(INPC,"1")

field(CALC,"d:=a+c;b")

field(OCAL,"d")
field(OOPT, "When Non-zero")

field(DOPT, "Use OCAL")
field(OUT,"d PP")

}

Hi Tim

I changed my program and use the OOPT field in record c, but the result is same. It sets the value c=0 when b=0 and record d keeps the last value that is fine, but when I again put b=1, it starts from the starting point but not from the last value it keeps which I do not want. I want that my record d keeps the last value when b=0 and starts from this value when I again put the b=1.

record (bi,"b"){
field(FLNK, "c")

}

record (calcout, "c"){

field(SCAN, "1 second")

field(INPA, "c")

field(INPB,"b")

field(INPC,"1")

field(CALC,"B=1?A+C:0")

field(OOPT, "When Non-zero")

field(OUT,"d PP")

}

record(calcout, "d"){

field(INPA, "c")

field(INPB,"1")

field(CALC,"A+B^2")

}

regards,

Hi Tasaddaq,

You can use the OOPT field to specify when the output link should be executed.  c.OOPT="When Non-zero"

Subject: how NOT to update the record

Dear all

I have three records, when the value in the record "b" is "1" the value in the record c is calculated and the record d is updated as well. Upto this the things are working fine. But I want one more thing that when the b=0, the value of record "c" should become the zero (that is happening) but it should not send the value zero to the record d means at b=0 record c should be updated but it should not update the record d. I want to keep the last value of record d so that when b=1 again then record d should start from the last value that it will hold. Please tell me how to do this?

record (bi,"b"){

field(FLNK, "c")

}

record (calcout, "c"){

field(SCAN, "1 second")

field(INPA, "c")

field(INPB,"b")

field(INPC,"1")

field(CALC,"B=1?A+C:0")

field(OUT,"d PP")

}

record(calcout, "d"){

field(INPA, "c")

field(INPB,"1")

field(CALC,"A+B")

}
