Automation and machine safety vendors SICK, Rockwell Automation, and Omron Electronics are developing an open protocol for safety communications. It will be based on common, standard protocol found in DeviceNet and Ethernet/IP and consists of an extension to the existing standard. The new safety protocol will allow standard and safety devices to operate on the same network and permit the latter to communicate across DeviceNet and Ethernet/IP networks to other safety devices with no extra programming.
The Industrial Internet of Things may be going off the deep end in connecting everything on the plant floor. Some machines, bearings, or conveyors simply donít need to be monitored -- even if they can be.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies.
You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived.
So if you can't attend live, attend at your convenience.
