In April, Jim Montague of Control Design wrote an interesting article on Machine Mount I/O entitled “Machine-Mount I/O Go Everywhere.” I think the article makes some very good points as to the value of why someone wants to move from inside an enclosure, or controls cabinet, to mounting I/O products directly on the machine.
He summarizes, with the help of a number of industry experts, the below points:
- Same or Better control performance out of IP67 products versus IP20 products.
- Installation time alone “is reduced by a factor of 5 to 10”
- Assemble more controls equipment faster with the same people & workspace
- Smaller & Simpler components take up less real-estate on the machine
I recently had the opportunity to attend Hannover Fair in Germany and was blown away by the experience… buildings upon buildings of automation companies doing amazing things and helping us build our products faster, smarter and cheaper. One shining topic for me at the fair was the continued growth of new products being developed with IO-Link communications in them.
All in all, the growth of IO-Link products is being driven by the need of customers to know more about their facility, their process and their production. IO-Link devices are intelligent and utilize a master device to communicate their specific information over an industrial network back to the controller. To learn more about IO-Link, read my previous entry, 5 Things You Need to Know about IO-Link.

When I am discussing with customers the use of smart sensors and smart devices in industrial automation, I always get posed with these questions:
- How do the smart sensors interface with the controller?
- How do you configure the device?
- How do you get diagnostics out of it?
- What other information can it provide?
This is sort of solved in a muddled world of proprietary communications or expensive network enabled sensors. But John and I have been talking for a long time about IO-Link, which can easily and cost effectively answer all these questions!

Valve manifolds, or islands or banks, are used by many automation engineers in their machine design. They are a great way to easily implement a large number of pneumatic motion applications while keeping the air infrastructure minimal. Recent demand in the market has driven manifold manufacturers to reluctantly embed network interfaces and remote I/O into their products. Customers tell me while manufacturer’s expertise may lie with the pneumatic side of the product; there is usually less knowledge with-in their organizations to work on the Ethernet side of the product.

There are many terms used for I/O technology in industrial automation: Remote I/O, Distributed I/O, Modular I/O, Expandable I/O, Block I/O, Conventional I/O and the list can go on. What do they all mean? Can they be used interchangeably? What is the difference?
Lets be honest… this is a muddled topic and many people use different things interchangeably. I’ve done a bit of research and reading of automation magazines, forums and websites and have tried to piece it together.

As many machine builders, OEMs, individual plants, and large corporations decide to move from the “bus” to the “net” (Profibus or DeviceNet to Profinet or EtherNet/IP) they have a chance to look at all the new architectures available and decide on which is the best for them. Here are the first two topics to take into consideration:

I recently watched a short webinar recorded by the PI North America organization and it really helped me understand the basics of how ethernet communication comes together. There are so many protocols and standards and they all communicate on the same media. Carl and Hunter do a good job presenting ethernet in a technical but easy to understand way.
The webinar is here. Their topics include:

As I sit and ponder what 2011 will look like, only one thought comes to mind, the endless possibilities of IO-Link.
I have written many entries on IO-Link and as I see it there are much more to come. Why more IO-Link? The answer is simple; we have just scratched the surface of the potential of what an IO-Link system can offer an end-customer or OEM. Let’s talk about a few upcoming milestones in 2011 to look forward to:

Let’s face it; an installed base, a trained maintenance crew, and an established set of procedures all make it really difficult to try to implement any new technologies in a running manufacturing facility. The idea of an industrial network providing detailed data about your processes and improving productivity sounds interesting and valuable, but where do you begin? Retrofitting everything with the newest technology isn’t an option in today’s economy, the capital investment is just too great. But there is hope! And with small steps, time and training, any plant can move forward into the ethernet realm and beyond.

“I already have an existing network (PROFIBUS, PROFINET, EtherNet/IP, CC-Link, etc…) so why would I be interested in an IO-Link enhancement?”
The answer is simple, instant SCALABILITY!
What do I gain by having an additional 4 IO-Link channels?
