Carl,

Please provide a little more information about your problem:

+ What do you have operating in your plant that could cause the 3 V spikes on the fieldbus cable?
+ Can you describe the spikes -- rise and fall times, duration, etc.
+ What is the length of the fieldbus cable?
+ Is the fieldbus cable's shield grounded in only one place?
+ Is the fieldbus cable in the same conduit or the same cable tray as power or VFD cables?
