Super excited to share my latest tech adventure: An OEE Dashboard powered by FlowFuse Blueprints! And guess what? It took me just 45 minutes to set it up with real-time data!

Video example

This dashboard is created using ready-to-use blueprints from FlowFuse. I just customized the blueprint a bit to read real-time values from my virtual factory .

I integrated my Revolution Pi, which communicates with FlowFuse’s server via MQTT and connects to the virtual factory via OPC UA

Here’s what my virtual factory sends to Revolution Pi via OPC UA:
  • Good and bad parts
  • Run time
  • Stop time
And the best part? I plug these values into the blueprint, and voilà! The OEE formula works its magic to calculate OEE, Availability, Performance, and Quality.

Watch closely, and you’ll see the OEE changes as it tracks the good and bad parts being created. But wait, how did I crunch those OEE numbers? Let me break it down for you:
  1. Quality Calculation: I’m analyzing the production counts (Good and Bad parts) from my factory, which the S7-1500 PLC communicates via OPC UA.
  2. Availability Check: I’m evaluating the total available time, system stop time, and run time to determine the optimal metric.
  3. Performance: It is based on ideal production time, total parts created, and system run time to gauge the performance.
And here’s the magic equation:

​
OEE = Performance x Availability x Quality.

Node-RED Flow: You can use my Node-RED flow for reading from the virtual factory via OPC UA. It can also be run on your computer if you don’t have an Edge device.
