I agree that Ethernet in its current form is not suitable for the sensor and actuator level of the industrial automation hierarchy for a number of reasons so existing fieldbus standards such as FOUNDATION fieldbus and PROFIBUS PA (IEC 61158) and WirelessHART (IEC 62591) etc. will continue to dominate here. I also agree that a bridge to the IP world is required for the Internet connection to build the IoT. It is important to remember that the APPLICATION PROTOCOL is essential for interoperability and interchangeability. Ethernet media and TCP/IP is not enough to make things work together. Application protocols for common fieldbus protocols in use such as Modbus/RTU, HART/WirelessHART, FOUNDATION fieldbus, PROFIBUS, and DeviceNet etc. are already available, many of them since years ago; they are Modbus/TCP, HART-IP, FF-HSE, PROFINET, and EtherNet/IP respectively. Note that fieldbus protocols are automatically and transparently converted to their corresponding Ethernet application protocol, without having to manually map data. This converter is often referred to as a "linking device" rather than a bridge or gateway to highlight this important difference. I believe use of such linking devices, automatically converting the data on the underlying sensor/actuator bus to IP, will increase as IoT adoption takes off. This way you get the best of both worlds; the ruggedness, reduced wiring, long distance, device power, and hazardous area compatibility etc. of fielbuses with the Internet capability of IP.

Interesting piece. The IIoT will certainly revolutionize the way industrial companies function as well as contribute to greater efficiency in productivity.

How about I2oT instead?

Varun, excellent article.  I agree, even most of the VC community thinks of IoT only in consumer terms.  With 2 billion legacy industrial devices (run via ICS/SCADA systems with Modbus, BACnet and LonWorks)  and more are still shipping, there is a clear need as to how to incorporate them into new security policies, remote accessability and big data analysitcs. 

Network virtualization is an important upcoming technology that allows any organization with industrial control systems - utlities, oil & gas exploration, manufacturing, etc. - to integrate both the old world and new world onto a common network foundation with software-defined security and poiicies.  This enables these organizations to be more agile, more secure and far more innovative.

More often than not, with the purchase of a sports car comes the sacrifice of any sort of utility. In other words, you can forget about a large trunk, extra seats for the kids, and more importantly driving in snowy (or inclement) weather. But what if there was a vehicle that offered the best of both worlds; great handling and practicality?
As additive manufacturing (including 3D printing) becomes increasingly popular among businesses as a quick and easy solution to creating and evaluating prototypes and end-use products, the debate about whether to outsource production or to purchase equipment for in-house use is at the forefront of industry discussions.
With increasing terrorist threats overseas, organizations are thinking about how best to defend themselves here and abroad. Engineering can play a role, especially when it comes to putting a barrier between yourself and the bad guys.
Time to market is everything, but at the same time, you can’t sacrifice quality for speed. That’s where additive manufacturing comes into play.
In the last few years, use of CFD in building design has increased manifolds. Computational fluid dynamics is effective in analyzing the flow and thermal properties of air within spaces. It can be used in buildings to find the best measures for comfortable temperature at low energy use.
