How Predictive Maintenance Works with PLC, SCADA and IoT
A PLC can tell you whether equipment is running, stopped, at speed, or in fault. But is the equipment actually healthy?
That’s where IoT-based condition monitoring adds value.
A Real-World Example
Consider an industrial pump. The PLC shows that the pump is running normally. However, an IoT sensor detects that vibration and temperature are gradually increasing. This change can indicate a developing mechanical problem before the pump actually fails.
The solution doesn’t require replacing the existing automation system.
PLC + SCADA + IoT Sensors + Analytics
IoT sensors can add parameters such as:
-
Vibration
-
Temperature
-
Motor current
-
Energy consumption
-
Runtime
This information can be analyzed alongside existing PLC and SCADA data.
From Reactive to Predictive Maintenance
Instead of waiting for a machine to fail: Monitor → Detect → Analyze → Predict → Maintain
Maintenance teams can identify abnormal behaviour earlier, plan maintenance based on equipment condition, and reduce unexpected downtime.
The same approach can be applied to motors, pumps, compressors, chillers, fans, and other critical assets.
The Key Benefit
Predictive maintenance isn’t about replacing your PLC or SCADA system. It’s about adding the right data to make better maintenance decisions.
Your PLC tells you what the machine is doing. IoT can help tell you how the machine is doing.
