Hi,
      How i can enable logging of EPICS PV value?  For example logging input PV (record type ai or bi)  and even set PV (record type ao or bo) also.   
I have used Asyn driver for my application.

Thanks


The answer depends on:

- What do you want to log? (value? timestamp? alarm status? For outputs: also who changed it? from where? old and new value?)
- How long do you want to log? (just during a test setup? over long periods? forever?)
- What do you want to do with the information? (use it for debugging? create plots of values over time?)
- Where do you want to log? (local on IOC console? remote on a different, maybe central, server?)

If you supply a more complete specification of your request, people will be able to point you to the best solution.

Thanks,
~Ralph
