I/O moves out, in: Local input/output connections will shift to distributed, remote, embedded

Local input/output (I/O) connections account for most interconnections with DCS, PC-based control systems, and PLC system applications. VDC Research Group expects more distributed, remote, and embedded  I/O connections.

Natick, MA– While local input/output (I/O) connections account for the majority of interconnections with DCS, PC-based control systems, and PLC system applications, greater use of distributed and remote I/O connections along with direct embedding of I/O circuits in devices. These are among findings in the VDC Research Group market study Global Market Demand and User Requirements for Industrial Distributed/Remote I/O, Fifth Edition , conducted over the past spring and summer.
The VDC research details market size, segmentation, and forecasts for distributed/remote I/O products used with DCSs, PC-based control systems, and PLC systems in industrial applications. The results of extensive investigation into user needs regarding distributed/remote I/O hardware and related software products are presented and detailed profiles of major vendors are included.
Market segmentation and forecasts are provided by geographic region; by industries and applications; by types of buses/networks; by mounting configurations; and by channels of distribution. Vendor shipments of distributed/remote I/O products and market shares are provided overall, by classes of applications, and for each major geographic regions.
The report provides recommendations on how vendors (large and small) can enhance their market positions. These cover products and product features; software; industries and applications to target; geographic markets to target; channels of distribution; promotion; pricing; buyer education, and service.
Diverse information is included
I/O connects field devices to controllers and can exist either local at the controllers with hardwiring to devices, or distributed (remote) from the controller and connected to it via a bus or network. The study indicated local I/O accounts for the majority of connections for DCS, PC-based control system and PLC system applications. For all three product classes, shifts away from use of local I/O are expected, toward greater use of distributed/remote I/O and direct embedding of I/O circuits in devices. Displacement of local I/O provides growth for the distributed/remote I/O product market. However, the expanding use of devices with bus/network embedded interface circuits decreases the growth.
Worldwide 2008 shipments of distributed/remote I/O for industrial markets are estimated at $4,288.5 million and are forecast to grow at a compound annual growth rate (CAGR) of 8% to $6,308.9 million in 2013, VDC says. The market for distributed/remote I/O for use with PC-based control systems is smaller than the market for the other product types under study, but is forecast to achieve the highest growth rate through 2013. Displacement of DCSs and PLCs in applications will be a major factor in producing this higher growth rate. Average selling prices are forecast to decline for all three product classes. However, price declines are expected to be limited due to the rising prices of raw materials such as copper, and the increasing price of fuel which is driving up the cost of operations and shipping.
