Non-Ethernet device networks future
queried
According to a recent study, the future for non-Ethernet based industrial device networks looks increasingly narrow as Ethernet moves into the 'lower levels' of the industrial automation.
The ARC Advisory Group in the USA said that the future prospects for the traditional, non-Ethernet based industrial device networks looks increasingly narrow as industrial Ethernet continues ito move into into the 'lower levels' of the industrial automation 'hierarchy' ARC reported that the growth in shipments of traditional industrial device networks will continue through the end of the decade, but the rate of growth will slow from the double-digit annual gains witnessed to date, to more modest single-digit increases

The distributed control system (DCS) market in China is expected to grow at a compound average growth Rate (CAGR) of nearly 14% between 2005 and 2010 - in heavy process industries.
Pharmaceutical industry automation to grow
The pharmaceutical industry is in rapid transition from a supply-driven market to a demand- and service-driven market where manufacturing efficiency and responsiveness play a critical role.
The worldwide market for traditional industrial device networks is expected to grow at a compounded annual growth rate (CAGR) of 13.7% over the next five years.
The market totaled over 12 million nodes shipped in 2006 and is forecasted to total close to 23 million nodes in 2011.
Traditional device networks have been rapidly assimilated into today's automation hierarchies by virtue of their ability to dramatically lower wiring costs and increase network functionality.

Cost-effective assembly system installed
India based Avasarala Automation, has provided cost effective solution for a compressor assembly line for air-conditioner and refrigerator system.
According to vice president of ARC, Chantal Polsonetti: "The sustained value propositions of low cost installation and incremental functionality will contribute to ongoing growth in shipments, as will the use of device networks in specialty applications and as a low-level complement to industrial Ethernet architectures." He is the principal author of ARC's 'Device Networks Worldwide Outlook' study.
Device networks and OEMs - a number of the traditional industrial device networks have passed the very significant milestones of ten years of service and millions of nodes installed.
Adoption has been particularly strong in OEM machinery applications, said ARC in a report to manufacturingtagtalk.com, as standard and proprietary device networks are used to wire the millions of sensors, actuators, remote I/O, and other devices deployed.
Device networks help OEMs reduce hardware, installation and maintenance costs through reduced wiring requirements, remote access capabilities, and the ability to reuse configurations, profiles, and other software-based components.
Traditional device networks also enable incorporation of embedded, distributed functionality that can drive higher machine availability.
Device networks have to coexist with Ethernet - ARC said that the need for device networks to coexist with other types of industrial interfaces, including industrial Ethernet, is increasingly obvious.
While third parties and other entities are introducing physical layer connectors that enable hardware integration of disparate networks, network integration at a higher level delivers greater added value to the end users and OEMs who use device networks.
This type of integration is delivered in the support of common profiles, configuration tools, and similar software-oriented components that allow management of the separate entities as if they were part of a single solution.
* Device networks follow OEM market to Asia - OEM applications in a wide range of industrial machinery will continue to adopt and use traditional device networks due to the direct business benefits they deliver to both the OEM/system integrator and ultimate end user, resulting in a further increase in share of shipments.
As the machinery markets in China and the rest of Asia continue to represent the largest growth through the end of the decade, the increasing use of device networks by OEMs in these regions will drive geographic share growth.
