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.

Iterative design — the cycle of prototyping, testing, analyzing, and refining a product — existed long before additive manufacturing, but it has never been as efficient and approachable as it is today with 3D printing.
People usually think of a time constant as the time it takes a first order system to change 63% of the way to the steady state value in response to a step change in the input -- it’s basically a measure of the responsiveness of the system. This is true, but in reality, time constants are often not constant. They can change just like system gains change as the environment or the geometry of the system changes.
At its core, sound is a relatively simple natural phenomenon caused by pressure pulsations or vibrations propagating through various mediums in the world around us. Studies have shown that the complete absence of sound can drive a person insane, causing them to experience hallucinations. Likewise, loud and overwhelming sound can have the same effect. This especially holds true in manufacturing and plant environments where loud noises are the norm.
The tech industry is no stranger to crowdsourcing funding for new projects, and the team at element14 are no strangers to crowdsourcing ideas for new projects through its design competitions. But what about crowdsourcing new components?
It has been common wisdom of late that anything you needed to manufacture could be made more cost-effectively on foreign shores. Following World War II, the label “Made in Japan” was as ubiquitous as is the “Made in China” version today and often had very similar -- not always positive -- connotations. Along the way, Korea, Indonesia, Malaysia, and other Pacific-rim nations have each had their turn at being the preferred low-cost alternative to manufacturing here in the US.
