Edge Computing in Manufacturing: Why Processing Data at the Source Changes Everything
Every second, a modern manufacturing plant generates millions of data points. PLC registers cycle through readings, sensors capture temperatures and pressures, vision systems inspect parts, and motor drives report speed and torque values. The question isn't whether to collect this data — it's where to process it.
For the past decade, the default answer was "send everything to the cloud." But manufacturers are learning the hard way that shipping every data point from every machine to a cloud server creates problems: network bandwidth costs, latency that prevents real-time action, dependency on internet connectivity, and enormous cloud compute bills.
Edge computing — processing data at or near the source — is emerging as the practical answer for most manufacturing IIoT applications. Here's why it matters, how it works, and what to consider for your factory.
