IoT to triple the number of connected industrial control devices by 2020

According to ABI Research the increasing adoption of IoT within industrial settings will result in a substantial growth of the number of connected industrial devices, in particular industrial control devices like PLCs.

The research firm estimates that over the period from 2014 to 2020, the number of connected industrial controllers will triple; growing at an average rate of 20%.

“Compared to the general-purpose conventional networks, industrial networks are characterized by a large variety of technologies and communication protocols, whose combination is determined by the requirements of the specific application they address,” said Eugenio Pasqua, research analyst at ABI Research. “As a consequence, there is typically little interoperability with conventional networks, but also between different industrial networks. Sharing data among different facilities or with the higher levels of an enterprise remains a very challenging task within this context.”

The technological advances of the past decade are, however, slowly changing this. The diffusion of Ethernet and IP-based industrial protocols, as well as the improved intelligence of industrial devices, have reduced the differences between conventional and industrial networks. This enables an easier interconnection between enterprise IT applications and OT systems, including the industrial equipment and the associated software, such as SCADA. ABI’s report cites firms like ABB, Siemens, Schneider Electric, and Rockwell Automation among the major vendors helping industrial organizations in this technological shift.

“Through the adoption of IoT technologies, industrial organizations can make better use of the huge amount of data generated inside their facilities and extract more meaningful information. This allows a better vision of what happens along the whole supply chain, achieving better performance at lower operating costs and the ability to react faster to changes or issues,” Pasqua said. “The number of potential benefits as well as the increasing pressure from the market are pushing industrial organizations towards this direction, and in the near future we will see more and more industrial facilities opening up their ‘silos’ and sharing their data with the higher levels of the enterprise, connecting their operational and business domains.”

These findings are from the Industrial Network Technologies and Control Systems: The Opportunities and Challenges for IoT Services and Platforms report, which is part of the M2M and IoT Platforms and Services Market Research.
