Is it possible to call the Ignition scripting functions from an external program?

Essentially what I’m wanting to do is to access the historical data using the system.tag.queryTagHistory and system.data.ToCSV functions to return the CSV data to an external program.

Thanks.

Not directly like you’re probably hoping.

You could use the web services module to build your own endpoints that in turn called whatever scripting functions you like, however.
