Wago 750 reliability

[Eric Williams <ECWilliams@lbl.gov>]

Does anybody here have any experience they can share on the reliability 
of the Wago 750 fieldbus system?  We've had a few problems with the 12 
units we've fielded here, but they were installed inside our storage 
ring tunnel and I suspect the radiation was a factor.  We're considering 
using it in more places outside of the ring, but reliability is a 
concern.  Thanks!
