Could you please help me with a python script to change the Start Date of OSIsoft PI system Data Retrieval settings?

[Yahya Alramadan]

I would like the code to change the OSIsoft PI data retrieval start time based on the document property input field named StartTime. Any help is appreciated.

If you want your PI function start time to come from a document property, you won't need a python script, you just need to map your start time to your document property. If that's not what you are trying to do please elaborate.

Thanks Atheer for your reply.

 

Actually, it is not a data function. The start time settings can be accessed through a window prompt under the Data Retrieval tab when I add the OSIsoft PI AF as a data source (or edit its related data table) as you can see in the screenshot.

​

My goal is to be able to change that start time through a document property. Trying to reference the document property in the start time field in the prompt (i.e. using ${StartTime}) does not work since it is not a valid format for the AFTime (see the second screenshot).

I see you are accessing PI connector through the GUI, is there any reason you can't use the custom data function?

Have you checked the tutorial here

Atheer,

I was able to achieve my objective with the custom data function. In fact, refreshing the data function takes less time when compared to data value retrieval through the GUI!

Thank you very much for your reply, the tutorial and the YouTube video. They helped a lot.
