Re-structured specification features key revisions, updates
CAN in Automation has re-structured the CiA 417 specification to incorporate virtual devices with CANopen protocols.
CAN in Automation (CiA) now provides the CiA 417 specification on its website (www.can-cia.org) to be downloaded free-of-charge.
The completely re-structured specification is partly incompatible to version 1.0. In particular, the specification for some virtual devices such as car drive has reportedly been revised significantly.
Also some PDO specifications have been updated. The SIG (Special Interest Group) CANopen Lift will continue to add new virtual devices, but it is not intended to change the technical specification of the just released version 2.0.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
