So then your grid would be variable Tag[x,y], for x = 0 to Max x Array Value, and for Y = 0 to Max y Array Value. If you are using RSLogix 5, you could use two FOR-NEXT loop instructions (FOR instruction) to display the tags in an array.
Or you could just type in the tag positions as grid constants (same tag also shows up at same spot in your Panelview grid).
