I am currently working on a project that is using an Arduino controller (currently using the AutomationDirect P1AM-100) and I would like to use Excel's Data Streaming function to save the different types of signals the controller is reading in.
The controller is reading in voltage, current, and power signals from an external power supply unit via ethernet; temperature readings from external thermal controllers communicating via RS485; and analog signals from pressure transducers.
My question concerns how the Data Streaming program reads in these values from the controller, is it just reading in what appears on the serial monitor and recording those values? Or is it actually reading in the signals from the ports themselves?
I can't find a specific answer for this online so I came here to ask.
