Protocol compatibility, multiple I/O types: Wago
I/O module compatibility, ability of a node to accommodate multiple I/O types, and I/O module size, are important I/O topics, says Wago.

I/O module-related issues include compatibility, ability of a node to accommodate multiple I/O types, and I/O module size, says Charlie Norz, product manager, Wago-I/O-System.
Fieldbus independence is a pressing issue for customers integrating existing systems or buying I/O "bit by bit," Norz explains. Customers "need I/O that will easily integrate with, and support, protocols that are already in use or meet customer specs." Some I/O modules and systems accommodate more than 16 prominent protocols, he says.
Ability for different I/O types to reside in one node (such as high-voltage and low-voltage types along side intrinsically safe modules) increasingly has become a "time- and cost-effective workaround for process application engineers." Working with one system and set of components to handle multiple functions is easier.
Machinery downsizing also has been problematic, Norz says, particularly as machines have become more sophisticated and every millimeter of panel must be maximized. Putting more I/O points in less space is the answer; some I/O modules accommodate up to 16 points within a 12 mm-footprint, conserving space and significantly lowering per channel costs through accessories, such as flat-ribbon cables and pre-assembled assemblies, Norz explains.

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
