Unplanned Automation Failures

Few issues create more disruption in an industrial facility than an unexpected automation failure.
Production stops, engineers are called away from planned work, operators are left waiting for answers and operational pressure increases immediately.
​
While occasional failures are inevitable, repeated unplanned automation failures are often a sign of deeper reliability issues within the control system infrastructure.
​
At Stratos Control Systems, we help engineering teams identify the causes of automation failures, improve system reliability and reduce downtime risk across industrial operations.
​
Why Unplanned Automation Failures Are Increasing
Many industrial facilities operate a combination of:
​
-
Legacy PLC systems
-
Ageing control panels
-
Older SCADA platforms
-
Mixed automation architectures
-
Third-party equipment
​
As systems age and become more complex, the likelihood of unexpected failures increases.
​
At the same time, engineering teams are under pressure to maintain uptime while managing limited resources and competing priorities.
Common Causes of Unplanned Automation Failures
Ageing Automation Infrastructure
Older automation systems often suffer from:
-
Component degradation
-
Communication instability
-
Reduced manufacturer support
​
Failures become increasingly difficult to predict and recover from.
​
Poor Documentation
Missing or outdated documentation can make even simple failures difficult to diagnose.
Common issues include:
-
Missing PLC backups
-
Inaccurate drawings
-
Poor revision control
​
Integration Problems
Failures often occur where systems interact.
This includes:
-
PLC to SCADA communication
-
Third-party equipment
-
Industrial networks
-
Data collection systems
​
Reactive Maintenance Practices
When engineering teams focus on restoring operation rather than addressing underlying issues, reliability problems continue to grow.
​
Signs Your Facility Is Vulnerable to Unplanned Automation Failures
-
Common warning signs include:
-
Increasing fault frequency
-
Recurring downtime incidents
-
Ageing PLC hardware
-
Communication instability
-
Poor system documentation
-
Growing maintenance backlogs
​
These indicators often suggest reliability risks are increasing.
The Hidden Cost of Unexpected Failures

What Reliable Automation Systems Look Like
Reliable systems are typically:
-
Well documented
-
Standardised
-
Properly maintained
-
Easy to troubleshoot
-
Supported by modern infrastructure
​
These characteristics help reduce downtime and improve operational resilience.
How to Reduce Unplanned Automation Failures
Modernise High-Risk Systems
Replacing ageing infrastructure can significantly reduce failure rates.
​
Improve Visibility
SCADA and monitoring systems help identify issues before they become failures.
​
Standardise Automation Infrastructure
Consistency improves maintainability and troubleshooting.
​
Improve Documentation
Accurate documentation speeds up fault diagnosis and recovery.
​
