There are lots of ways to move data to/from a controller. The best way for you situation will depend on a few things. Sounds like you’re well on your way to creating some text files on your PAC Display PC which you’d like to get onto your controller?
The first solution which pops in my head involves turning your PC into an FTP server, so your controller, using FTP and perhaps file communication handles, can pull those files from the PC for parsing into whatever variables need loading up in your strategy. Although I’ve used the built-in IIS Windows features to turn a PC into a FTP server in the past, IIS tends to cause me to use bad words. The FileZilla server, on the other hand, is simple (free) and works great.
Once you have your controller and PC communicating with each other via FTP, there are several options for how you’d parse that data into tables. What will your files look like (do you have control over that?), and what kind of tables are we talking about here?
