Unity Pro, Modicon M340 Trending Issues

Greetings,

I'm using Unity Pro v8 (131118) with Modicon M340. I cut my teeth on PLCs with Modicon back in the early 90s but this is my first Unity project.

I'm having two issues I am hoping someone can help with.

1). I created a trend Friday and run it, but after a short while I got an error message

"Low Disk Space! Recording Stopped."

I have 5gb free on my C:\ and 50gb free on my data drive, so that's not it.


2). Now today I when I run a trend ("record"), the curves don't show up on the graph, it's just a blank graph. I still get the "Low Disk Space! Recording Stopped." message a short time later, so it would seem it's doing something but not showing the results.

Anyone have any suggestions? I tried re-creating the trend from scratch, same results. I rebooted also, same results.

Thanks,
-Brad

The trend curves are back and working, but no idea why.

Still struggling with the low disk space message.
