Great point, TJ. Certainly engineered cables need to be designed carefully and tested extensively at longer distances. If it isn't right, I'm sure Rockwell will find out about it. But that's still a legitimate concern for system engineers.
The important part of single cable servo hardware is the cable. Rockwell will need to impress experienced engineers that they've designed the cable so that the feedback signals are immune to the noisy power signals.
Obviously added EtherNet/IP to their mid-range motion control offering is the main story, but the single cable combining power and feedback might be the most unique benefit. Also covers both servos and induction motors with single platform.
Yes, it seems to be the case, you're right. Putting more functionality in one device reduces the need for multiple components, as you point out. And Ethernet/IP is becoming more prevalent in device design as it seems that everything is required to be connected to a network these days.
Elizabeth, it seems that the trend is to increase integration of these types of devices. Many in the past were made up of separate components. The use of EtherNet/IP also eases integration and cuts costs. Interesting application.
Last year at Hannover Fair, lots of people were talking about Industry 4.0. This is a concept that seems to have a different name in every region. I’ve been referring to it as the Industrial Internet of Things (IIoT), not to be confused with the plain old Internet of Things (IoT). Others refer to it as the Connected Industry, the smart factory concept, M2M, data extraction, and so on.
Some of the biggest self-assembled building blocks and structures made from engineered DNA have been developed by researchers at Harvard's Wyss Institute. The largest, a hexagonal prism, is one-tenth the size of an average bacterium.
