Thanks Flex727 - no, I didn't add any tape or screw it down.
I rerouted some IO away from 575 and motor leads, after doing that the results were dramatic, I went from a fault every 15 minutes to one fault after 14 days.
I am ordering a new Snap IO Module and V570, was talking to Micheal from Unitronics just now, and the thought was that the unit could be degraded from all the previous noise exposure.
It is probably a long shot, but something we are going to do.
I am also going to be probing for noise as well at checking all grounding.
One last item to try was to float the 24VDC power supply from earth ground.
With the new unit, I will tape where I can to keep the Snap IO fixed to the V570. The current snap IO module is very secure and snug with the V570, but I will try what you recommend.
Problem is, if it is only happening every two weeks, and I change more than one thing at a time, then I will not know with certainty what corrected this issue.
