From Larry O'Brien at ARC:
I recently published this survey on the operational and maintenance costs benefits of Foundation Fieldbus and would love it if you could post it on your blog or just pass it around.
Best regards,
Larry
Foundation Fieldbus has found mainstream acceptance in the world of automation, but little is known about the real work operational and lifecycle cost benefits that are being realized by end users. The purpose of this survey is to ascertain a more accurate view of the operational, maintenance, and engineering benefits related to Foundation Fieldbus and how they relate to a business value proposition for end users.
