Offhand Noise Comment

Posted by & filed under Uncategorized.

Funny coincidence: yesterday I mentioned using fiber optics for noise immunity (and thinking I probably should have expanded that thought) and today’s email brings reference to an article at Control Design, “More Than a Backbone.”  The article meets my deserves-a-mention criteria by presenting some useful information… and using one of my favorite p-words – PROFIBUS.  And of course every time it says “Ethernet” I think “PROFINET.”  This is a logical substitution; PROFINET uses standard unmodified Ethernet after all.  So, for more on using fiber optic cable instead of copper read the article.
