You will need to 'wash' the CSV via a bit of OptoScript to put it into a string table or some such in the controller.
In other words, there is no method for PAC Display to display a CSV file natively, and as yet there is no CSV gadget in groov.
They both however can display strings, so it would be a matter of you figuring out what is the best way to take the CSV file and splitting it into strings to be displayed in either product.
Musing out loud here..... You raise an interesting point that we hear from time to time (not all that often, but often enough, if that makes sense).... That is, people have a CSV, or a DB and they want to view it in some Opto product. To them, since it's their data and since they are familiar with it, it seems to be a simple task. I mean, really, how hard can it be, its my data, just display it already.
The problem is, what works for one CSV/DB may not work for another. Where does the data wrap around, how many parts of data are in each structure, does it change during the course of the day (shift work) and so on.
When you dig deep into how to display the data on both PC, Tablet and Smartphones, the complexity gets out of hand pretty quick.
Then you have the end user challenge. They expect it to be a given way, 'Just make the computer show it how I want it'. As you know, that's not always possible. We had this on the submarine job I worked on. (The user in this case was a well known movie director).
Long story short, if you move ahead with this job, and you have a moment, lets know what you come up with.
