PIconnect 0.9.1

Python connector to OSIsoft PI SDK

A python connector to the OSISoft PI and PI-AF databases

This connector allows access to the OSISoft PI System through their proprietary SDK. It provides a number of classes, mostly mirroring the AF SDK structure, but at the same time implementing the cool stuff we use Python for. Connections to the database are therefore implemented as context managers, to allow opening a connection using a with statement.
