Thanks for the kind words. Having worked in the Automotive Industry, modular design was the mantra for all design engineers. The vehicle communication bus protocol back in the early nighties of Chrysler Vehicles were proprietary based and made it difficult for service mechanics to run diagnostics because of non -interoperability. Even with the PLC based automation controls in the assembly plants, networking different vendor's machines was quite a challenge because of different protocol standards and specs. The NetJack would have made our lives (the Electrical Plant Engineers) easy because of the modular approach to networking and protocol management.

Thanks. The concept of plug in modules is to remove the complexities of building discrete circuit interfaces which always provides a challenge to the overall system integration phase of product design. The modular approach to equipment machine design just seems to make logical sense in the grand scheme of New Product Development. Nice article!
For years, I've been hearing suppliers talk about the possibility of having the engineer focus on the machine requirements, instead of the networking protocol. In the end, though, those suppliers were usually pushing one proprietary protocol. Seems like this plug-in module finally makes it possible to turn the vision to reality. Nice to see the optimism in your comment, mrdon.
Hi, mrdon. Exactly. The modular approach also simplifies the equipment design because engineers would not wonder if their communication interface worked properly. One less "unknown" to wrestle with when bring up a prototype or testing equipment in the field. --Jon
A plug in module such as this would definitely help equipment machine designers because of the interoperability with various fieldbus products and protocol standards available. The Hirshler plug in module will allow the equipment machine designer to focus on the functional requirements of the machine instead of the networking infrastructure which requires significant design/implementation time .
I am currently using the PCI slot mounted version Hilscher cifX card. They have versions that will handle a number of the industrial Ethernet flavors (Ehternet/IP, EhterCat, Sercos, etc.), and ones that will handle Profibus, Canbus, DeviceNet, etc.
Switching to a different network involves switching out the PCI card with the appropriate version for the desired protocol. The software basically doesn't change.
I haven't used the plug in style, because our products don't currently have a form factor where it would be usable. My experience with the cifX PCI slot version has been generally positive. I have used the Ethernet/IP version, and the Profibus versions, both connecting to Allen Bradley PLC's.
By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
In a world that's going green, industrial operations have a problem: Their processes involve materials that are potentially toxic, flammable, corrosive, or reactive. If improperly managed, this can precipitate dangerous health and environmental consequences.
With LEDs dropping in price virtually every year, automakers have begun employing them, not only on luxury vehicles, but on entry-level models, as well.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
