Unplanned Automation Failures

Industrial Machinery

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

  • Obsolete hardware

  • 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Missing or outdated documentation can make even simple failures difficult to diagnose.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:

​

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.

​

The Operational Impact of Unplanned Automation Failures

Production Downtime

Unexpected failures interrupt production and affect operational performance.

Even short outages can create significant disruption.

​

Increased Engineering Pressure

Engineers must:

  • Diagnose faults quickly

  • Restore systems safely

  • Manage operational expectations

This creates significant workload and stress.

​

Higher Maintenance Costs

Unplanned failures often result in:

  • Emergency callouts

  • Overtime

  • Contractor dependency

  • Expedited replacement parts

​

Reduced Confidence in Automation Systems

Repeated failures can reduce trust in the reliability of the automation infrastructure supporting production.

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

  • 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.

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.

​

How Stratos Helps Reduce Automation Failure Risk

We help engineering teams:

  • Improve reliability

  • Reduce downtime

  • Modernise ageing systems

  • Improve visibility

  • Reduce recurring failures

Reduce Failure Risk Before Downtime Increases

If unplanned automation failures are affecting your operation, now is the time to address the underlying causes before reliability and downtime continue to worsen.
