Safety bus networks set for rapid growth
The global market for distributed/remote I/O using safety buses/networks remains small, but high growth awaits, according to a recent study.
The global market for distributed/remote I/O (DRI/O) using safety buses/networks remains small, but high growth awaits, according to a recent study from VDC The study: "Industrial distributed/remote I/O: Global market demand analysis and user requirement analysis, 4th Edition", indicates that safety buses/networks accounted for 1.3% of global DRI/O shipments in 2005 and forecasts 2010 shipments to be 2.3%

Distributed/remote I/O for use in PLC system applications had the highest utilisation of safety buses/networks.
On the other end of the spectrum, only a fractional share of products for PC-based systems are equipped with safety bus capabilities.
"PLC system applications are the most attractive for safety buses", says VDC analyst Jake Millette.
"This is due to the high level of shipments for equipment and machinery in discrete manufacturing compared with process controls".
"The development and promotion of safety buses by PLC suppliers such as Siemens has also lead to a greater adoption".
In 2005, Profisafe accounted for the largest share of the overall market and of distributed/remote I/O for use with DCSs and PLCs.
This lead is expected to be held in 2010.
AS-i Safety at Work accounted for the second largest share of the overall market in 2005 and either led or was among the leaders for each product type.
However, DeviceNet Safety, just barely behind AS-i Safety at Work in 2005, is forecast to take second place by 2010.
The safety bus/network arena will likely become more crowded in coming years.
Ethernet/IP Safety is close to release and the Safetybus p Club is developing its SafetyNet protocol.
These reflect the general trend to Ethernet solutions in the safety bus/network market.
