Naw, it's not really all that interesting. A SCADA system has a bunch of field devices it needs to talk to. Most SCADA software has some method of importing lists of device information and creating objects from it.

My engineer gives me a list of (for example) valve actuators on a site. I open that list in Emacs, manipulate it a bit, and then use it as input to a function I've written. That function generates a CSV file with things like tag name, Modbus ID, polling method, etc. that I can import into Wonderware. It's considerably faster and less error prone than manually creating and configuring hundreds of instances.

I say it's not interesting because most people in my position write little bits of code like this to automate the repetitive parts of our jobs. I just do it with elisp instead of Excel or Python.
