This article answers the question... What are PLC controller failure rates? It also covers equipment failure rate from a PLC failure rate perspective (automation controller).
What's your war story?
#1 Factor: Environment
#2 Factor: Brand/Model

#4 Factor: PLC Management
WHAT? (From most likely to least.)
- PLC output modules
- PLC input modules
- PLC communication modules
- PLC power supply
- PLC processor module
All Equipment Failure (physics)
- Mechanical devices are more likely to fail than electrical,
- Electro-mechanical devices are more likely to fail then solid-state devices,
- High current devices are more likely to fail than low current devices.
