“We are convinced that today's great variety of automation technology requires a new conceptual approach to simplify integration of machinery in manufacturing,” said Peter Lutz, Managing Director of Sercos international. “For this reason, we have cooperated with ODVA and the OPC Foundation in identifying topics that result in considerable technical and market synergies for users and providers.” 
   
Specifically, the deliberations focused on how to implement a joint network infrastructure in which the different network protocols can coexist and the devices of different manufacturers can be operated together. This approach is intended to support mechanical engineers and users in reducing the complexity and costs of device integration in machines and systems. It also enables mechanical engineers and users to select preferred product providers and to utilize their devices. 
   
Blended infrastructure with Sercos and EtherNet/IP devices, Courtesy: SercosBecause the infrastructure required for EtherNet/IP and Sercos III includes the physics and data link layers of Ethernet, Sercos telegrams, CIP messages and TCP/IP messages can coexist within a network without requiring additional cables. To keep the cyclical and clocked communication of Sercos III intact, the CIP messages and TCP/IP messages are transmitted in the Unified Communication Channel (UCC). This channel sits directly on the Ethernet layer without tunneling, allowing the connection of users who do not have Sercos III, but instead support a different Ethernet-based protocol. 
   
This approach allows the combination of Sercos III devices, EtherNet/IP devices and other Ethernet devices in a joint network infrastructure in a machine or system. The existing Sercos III and EtherNet/IP specifications do not have to be modified, as the respective communication mechanisms have already been integrated in the Sercos III transmission process. 
   
By late 2012, the providers aim to create an implementation guide that describes the planning and set-up of such multi-protocol networks. Initial prototypes are expected to be presented at the SPS/IPC/DRIVES 2012 show as a demo system.

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.
