Unleashing the Power of Ethernet/IP
Manufacturing automotive powertrain components and systems has evolved into a complex system. In fact, more than one industry leader has stated that the automotive industry is always on the bleeding edge of integrated manufactur- ing solutions. Te increased complexity of CNC systems, programmable logic controllers (PLC) and manufacturing execution systems (MES), as well as more advanced supervisory control and data acquisition (SCADA) systems, has led the industry to new levels of integra- tion between motion control, distrib- uted I/O, and manufacturing informa- tion systems. Additionally, these systems need to be integrated across multiple suppliers’ machines in continuously shorter project cycles. To address the market challenges of
the increasing complexity of machine systems, new safety and security requirements and the growing impor- tance of information technologies, new standardized field bus architectures have been developed and are now being implemented across a wide spectrum of powertrain manufacturing ap- plications. Tese solutions integrate CNCs and robots to cell controllers so manufacturers can more easily manage operations across equipment controlled by the two systems. Tis provides cost efficiencies, reduced setup, better part quality, safer work environments, usable manufacturing intelligence and overall increased productivity. Additionally these systems also integrate into the Industrial Automation Controls System (IACS) networks that are becom- ing more prevalent in the automotive manufacturing environment.
Industrial Automation Controls Systems (IACS) As the industry is continually faced
with development of “better, stronger and faster” products, manufacturers are realizing the business benefits of con- verged manufacturing and enterprise networks. Te IT integration with IACS enables plant-to-business network con- vergence, which in turn drives strategic business decisions that are backed by real-time data from IACS. IACS, Process Automation Systems,
Process Control Systems, Supervisory Control System and Data Acquisition Systems are all a part of the significant integration of data systems. All of these
Data sharing isn’t the world of the future, it’s the world of now, and CNC must be integrated into it.
systems have benefited greatly from the transition to modern Ethernet and Ethernet/IP field bus networking technologies from the vendor-optimized networks typically used in the past. Information sharing and stream-
lined efficiency will be the result when the information contained within the IACS is available and shared through- out the larger enterprise. Manufactur- ers and industrial suppliers are discov- ering that standard communication architectures and uniform networking of an IACS is the key to optimized services, greater visibility and lower total cost of ownership (TCO). And as the industry develops to higher integration levels, manufacturers are moving to embrace standard informa- tion technology, particularly standard

Converging Networks Te industrial manufacturing data
collection environment has been, and continues to be, very similar to the IBM legacy mainframe environments that were in use in the late 1990s. Although the current legacy industrial systems are functional, they are costly to maintain, difficult to connect and slow to evolve. Te current IACS systems in place are oſten a mixed bag of discrete, process, batch or hybrid systems. And while manufacturers need their systems to interact in real-time with the other enterprise applications, supply chain partners, and outside manufacturers, these systems are extremely difficult to integrate. To accomplish this integra- tion, manufacturers are converging their IACS networks with their enterprise networks. However, this convergence leads to a number of issues: • Maintainability and Reliabil- ity—As manufacturing opera- tions become globally integrated, manufacturers are challenged to provide consistent access to data while making the manufacturing environment flexible. Security, availability and asset use are critically important to manufac- turing companies because IACS equipment is mission-critical, and efficiency is critical in main- taining a competitive edge.
• Implementation Costs—Legacy IACS systems, although oſten fully depreciated in existing manufacturing environments,
