Fieldbus uptake on a downward curve

摘要

Following the findings of a new study by IMS Research, Tom Moore, analyst - Discrete Automation, looks at the future of an industrial fieldbus infrastructure and asks, is it sustainable? Anew study by IMS Research (now part of IHS Inc) has estimated that fieldbus protocols accounted for 75% of new industrial automation component network connections in 2011. This is projected to fall to 69% in 2016. New network connections using fieldbus protocols are still some way ahead of Ethernet, yet growth of Ethernet connections is expected to be considerably higher by 2016.
