IIoT Machine Monitoring: Measuring What Improves OEE
Gateway architecture and signal selection for retrofitting monitoring onto mixed-vintage machine fleets.
Overall Equipment Effectiveness (OEE) only improves what you measure. The challenge on a mixed-vintage shop floor is getting a clean signal from every machine.
Edge gateways bridge the gap. They read PLC outputs, dry contacts and current sensors, then normalize the data into a single stream. A 1990s press and a 2020s CNC center end up speaking the same protocol.
Signal selection matters more than sensor count. A single run-status and a part-count pulse will drive availability and performance. Quality comes from the inspection system, not the machine.
Measure those three, display them where operators can see them, and OEE stops being a monthly report and starts being a daily habit.
