The IIoT can be a pretty foggy and technologically diverse topic for anyone to understand. And there are so many competing standards out there today that it’s tough to identify which path to take. But a new platform built upon an open source, extensible framework for IIoT technology called EdgeX was recently announced, and it may be just what the industry needs to part the clouds of confusion and shine some clarity on the IIoT.
