For a while it appeared that all production information was on its way to the cloud, but those services and their developers and users have since realized there was far too much data for them to handle, while many networks still face connectivity, latency and reliability hurdles.

Fortunately, edge computing in or close to sensors, instruments, analyzers, I/O, controls and other plant-floor devices is enabling routine data gathering, storage on databases and latency-reducing data processing in many process applications, while also delivering less burdensome reports-by-exception, anomalies and longer-term trends for analysis to the cloud and other enterprise-level users.

Also in this issue are feature articles about process automation and industrial Ethernet.

Find all of this and more in the February issue of Control.
