I want to make queries to the PI System in order to obtain values of some PI points

Hello (Missing Content)​,

Could you please provide an example of your goal? thanks.

What we want to achieve is to use python to obtain values of specific pi points, to be able to process them, we are aware of the PI Web API but this module is not within our license so we are looking for a way to do it through queries. 

Wow, this becomes an uphill battle.

For python, PI Web API is the officially supported PI developer technology.

You could use AF SDK, but that is not officially supported by AVEVA for python. Note that AF SDK uses .NET Framework, so you will be restricted to a Windows machine that resides on the same domain as the PI Servers. As it is not officially supported, Tech Support will not be able to provide help.

There are old PISquare posts regarding python, .NET Framework, and AF SDK. There are quirks with using it because there are significant differences between the general python language and a .NET Framework virtual machine.
