channelarchiver¶
A python client for retrieving data from an EPICS Channel Archiver.
To get started just import the Archiver class and specify the
address of your Channel Archiver server:
>>> from channelarchiver import Archiver
>>> url = 'http://cr01arc01/cgi-bin/ArchiveDataServer.cgi'
>>> archiver = Archiver(url)
You then fetch data with the archiver.get() method:
>>> data = archiver.get('CHAN:MON', '2013-08-11', '2013-08-12')
>>> print(data)
