Re: Record for a running sum

[William Layne via Tech-talk <tech-talk@aps.anl.gov>]

I can think of two ways to do it passively. Both end up using a calc record. I'll post below a real quick snippet that uses a channel access link to passively sum changes to a record. Or, you can have the record you care about forward link to the calc record. 

record(calc, "$(PV)_SUM")

{

    field(DESC, "Running sum of $(PV)")

    field(CALC, "VAL+A")

    field(INPA, "$(PV) CP")

}

Hello,

I developed an IOC for the radiation monitors found throughout our
laboratory. Through this IOC I am able to read in the values of each
probe and display them nicely using CS-Studio. However I would like to
add the ability to the IOC to keep a running sum so I can calculate the
cumulative monthly and yearly doses throughout the laboratory but I am
not sure how to implement this. I tried searching for similar projects
of examples, but without any luck. Would you be able to provide me with
some pointers onto how to implement such a feature?

Regards,
Donny
