Re: Does anyone have documented PV Access run time ENV variables?

Hi Kuktae,

 

This is probably not what you are looking for, or at least not nearly the full story, but maybe helps:

 

https://github.com/epics-base/pvAccessCPP/wiki/protocol

 

Also, Michael Davidsaver has written documentation for PVXS:

 

https://mdavidsaver.github.io/pvxs/overview.html

 

This goes a bit more in the direction of user documentation.

 

And, partially, but not only because of this, we are preparing an EPICS Document-athon at ESS end of August (28.August – 1.September, 2023).

I will prepare an announcement – or first “save the date” kind of message – for that event as soon as I can figure out some details. But we have an OK for the event so it is going to happen.

 

 

Best regards,

 

Timo

Subject: Does anyone have documented PV Access run time ENV variables?

 

Hello everyone,

 

I am currently studying EPICS Channel Access (CA) and PV Access (PVAccess and PVXS), particularly the server/client-side environment variables used for run-time configuration. While researching, I came across very good documentation for EPICS CA, which can be found in the links below:

https://epics.anl.gov/base/R7-0/7-docs/CAref.html

https://docs.epics-controls.org/en/latest/specs/ca_protocol.html

However, I am having difficult finding good documentation for PVA on the EPICS base site:

https://epics.anl.gov/base/R7-0/7.php

 

Although, I did find some information on the PVXS site thanks to Michael Davidsaver, I still feel that is not sufficient. Here is the link to the information I found:

https://mdavidsaver.github.io/pvxs/netconfig.html

 

Could someone please point me in the direction of a reference document that provides more comprehensive information on PVA?

 

Thank you very much for your help.

 

Best regards,

Kuktae
