Replace Obsolete PLC and SCADA Systems Safely
We specialise in planned PLC and SCADA replacement projects that minimise risk
Obsolete PLC and SCADA systems present growing risks to production, safety, and compliance. As manufacturer support disappears and spare parts become scarce, even minor failures can lead to extended downtime.
​
Stratos Control Systems specialises in planned PLC and SCADA replacement projects that minimise risk, disruption, and unplanned stoppages.
​
Why Obsolete Control Systems Create Risk
Legacy control systems were not designed to operate indefinitely. Over time, they introduce increasing operational and business risk, particularly when knowledge is lost or systems are modified without documentation.
​
Replacing these systems requires careful planning to avoid introducing new failures.
Risks of Legacy PLC and SCADA Systems
​​
-
No manufacturer support or spare parts
-
Increased failure rates and unpredictable faults
-
Loss of system knowledge when engineers leave
-
Cybersecurity and regulatory compliance risks
-
Difficulty integrating with modern systems
Our PLC and SCADA Upgrade Approach
We manage PLC and SCADA upgrades using a structured migration process:
​​
-
Full audit of existing PLC, HMI, and SCADA systems
-
Migration planning using Siemens, Allen Bradley, or Mitsubishi platforms
-
Parallel testing to validate functionality before cutover
-
Staged commissioning to minimise downtime
-
Clear documentation and operator training
Why Planned Replacement Works Better

A planned replacement avoids emergency shutdowns, rushed installations, and undocumented fixes. It also creates a platform that is easier to maintain, safer to operate, and supported long term.
