Re: Integrating the past with the future

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.

Latest Analysis
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
Fifteen European research centers have launched EuroCPS to help European companies develop innovative products for the Internet of Things.
Get your Allman Brothers albums ready. The iconic Volkswagen Microbus may be poised for a comeback, and this time it could be electric.
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
