Futura Wizard Monitor Function..
Set to trigger on a fault. Will take a snapshot of 45 seconds of I/O at 10 FPS. You can then slow down the playback to view every I/O up to the moment of the fault.

IMHO...The greatest troubleshooting tool EVER...

TK has something similar on IMS, but not triggerable.

It Don't mean a thing if it aint got that swing.
