Compact Logix Bool bit can see a Light change state, but won't trend

[georgegraz]

I have 2 laptops - 2 different systems running. 1 I can show a light on the screen and I can trend that bit. Different Compact logix, I can show the light, but won't trend. CSV file shows the date/time column, but not another column showing true/false. I just convert all False to 0 (zero), and all Trues to 1. I can then trend them.
Thanks

I got it working. I finally copied one of the ones that was working, then pasted it. It created a new one BasicDataLogger12. But I tried double clicking them to see if they showed a difference, but they look the same.
Thanks
