Distributed safety IO modules without controller
SafetyBridge technology from Phoenix Contact allows a user to distribute I/O modules in a network without a safety controller.
Phoenix Contact’s SafetyBridge technology makes it possible to distribute safe I/O modules in a network without the need for a safety controller.
SafetyBridge technology allows the input and output modules to exchange safety-related signals with one another. Since the modules process the safety function themselves, the standard control system and network are only used as a transport medium. By eliminating the safety controller and safe fieldbus system, SafetyBridge technology can reduce the cost of a safety system.
The safety logic operations are directly processed in the intelligent safety output module. The safety modules can be distributed throughout an automation system using Phoenix Contact’s Inline Modular I/O. SafetyBridge easily integrates into Profibus, Profinet, Interbus, and EtherNet/IP protocols over Phoenix Contact, Siemens Step7, and Allen-Bradley RSLogix 5000 control suites.
The Safeconf software parameterizes the safety input and output channels and generates the safety logic. Pre-configured function blocks are available for almost any application.
The standard control only has to copy non-safety I/O data bidirectionally between the input and output modules. Consequently, the control does not handle any safety-oriented tasks.

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.
