3 methods
1) use Archies free AdvancedHMI and write what you need to
2) If this is a one off then save to L5K and find the Tag Values for the array and put them in manually
3) If you have access to OEM version of rslinx or better (Cannot use RSLinx Light) then use DDE in Excel with a bit of VBA programming
Aww archie beat me to it - what are you doing up so early?
