According to an article in EDN, a sister publication to Design News, the European Union (EU) has adopted three new regulations aiming to revise the New Regulatory Framework (NRF) for directives within its member states. The regulations, which the EU adopted in 2008, were all in force as of Jan. 1, 2010, and require a common framework for the marketing of products. The new regulations specify the format for any new directives the EU adopted, which require CE marking. CE marking is a mandatory conformity mark on many products placed on market in the European Economic Area certifying that the product has met EU consumer-safety, health or environmental requirements.
As of December 2009, the RoHS directive was not a CE-mark directive. However, the European Commission’s proposals to amend RoHS include changes that could make RoHS a “new approach” NRF directive requiring CE marking of products.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
