Experimental Physics and Industrial Control System
|
Hi,
in principal it is possible to have an archive engine and MySQL
database running on the pi. AFAIK not the CSS Archive Engine though.
But I completely agree with Kay: The Pi is good for running IOCs on
it, but I would not use it as storage.
We are operating Pis extensively for our control system and already
had to exchange several SD cards...
Using a linux PC for storage (and maybe also GUI) is definitively
the better solution.
Cheers
Florian

Yes. We intent to make the pi the only and complete control

If we cannot manage to do it in the pi. We will then go to the
option of using another linux PC to save the data.
Thanks

or more like one IOC in the control system?
It’s perfectly fine to run IOCs on the pi, but the
pi with its SD card for storage is not ideal as an NFS file
server or a relational database server (MySQL).
You can run MySQL on an ordinary Linux computer
with real disk, and then also run the archive engine and
client GUI on there, getting data from one or more IOCs on one
or more pies.

My professor suggested me to use the CSS
archive engine from SNS (oak Ridge,TN) available
here:

..
What i want is to store Epics PV's archive
in my raspberry pi. Do you have any better
suggestion compatible with CSS "Data-Browser" and
MySQL?
