Hello Murali,

Thanks for your reply to my previous inquiry regarding changing storage

intervals for individual PVs.

I've another question pertaining to editing the Protocol Buffer (.pb)

files that are generated by the Archiver Appliance.

We would like to edit these files and be able to add data to them for

the purpose of archiving it.

I used the Protoc compiler with the EPICSEvent.proto file at

https://urldefense.us/v3/__https://slacmshankar.github.io/epicsarchiver_docs/EPICSEvent.proto__;!!G_uCfscf7eWS!dyFziIhmsdDhIY6efdHwlY7o4fbdzIjiNxFet8oBjLeHIXBH4SK1bIVsgXQ8lzdOajQo1c4YoyhWo8MUy0l1NYVaRbm-M182$

to generate the code needed to access .pb files via Python, but the

resulting EPICSEvent_pb2.py file contains

only variable definitions, without classes.

If possible, could you provide a brief example and some pointers as to

how to go about editing .pb files and/or getting

data into the appliance by external means?

Thanks in advance,

Windsor
