The use of Ethernet with motor drives and motion controllers will more than triple to 2016 from 1.8 million new connected nodes
in 2011. According to a new study from IMS Research, the compound annual growth rate (CAGR) for new motor
control Ethernet nodes is projected to be the highest across the whole
industrial space at nearly 30%.
IHS
analyst, Tom Moore commented “Ethernet, particularly certain industrial
variants, is very well suited to drive and motion control applications. The
growing numbers of Ethernet protocols, which are high-speed, deterministic, and
low jitter, mean its application has never been easier. Some of the most suited
protocols are forecast annual growth rates exceeding 30% to 2016”.
As Figure
1 shows, new Ethernet nodes are forecast to account for over 20% of the total
new networked motor control products in 2016. This is a large increase from the
estimated 12% in 2011, when fieldbus protocols dominated new node connections.
Ethernet is quickly gaining ground in a market that is well known for being
reserved and slow to adopt new technology.
Moore
continued, “Part of the transition to Ethernet is due to the protocols
available, such as PROFINET, Ethernet/IP, POWERLINK and EtherCAT, which are all
very well suited to motor control applications. In particular, EtherCAT is well
known for very high speed data transmission and low response times. Its
adoption is forecast to grow very strongly to 2016, especially as its member
count continues to increase.”
Networking,
however, isn’t just about the technology or protocols on offer; it is about the
equipment itself. Nodes, the connections to the higher network, are set to
increase and part of this is being driven by an increasing number of ports per
device. This has an added affect to the adoption growth of networking
technologies. “The increase in node count has come about for several reasons,”
indicated Moore. “More and more products are being released with the ability to
daisy-chain, requiring at least 2 ports.”
Ethernet
is certainly making headway in the industrial space and its projected adoption
growth is set to outstrip that of fieldbus technologies in almost all applications.
“It is forecast that in 10 to 15 years Ethernet will have replaced fieldbus as
the mainstream networking technology for motor control products.” says Moore,
“This can only be good for the unification and simplification of networking
solutions; driving down costs and increasing up-time”.
