Control System Upgrades
Control system upgrades help industrial businesses replace obsolete hardware, improve reliability, and support long-term performance. At Stratos Control Systems, we deliver upgrade projects that integrate with PLC programming, improve visibility through SCADA systems, and align with wider automation strategies.
​
We work with engineering and operations teams to modernise ageing systems safely, reduce downtime risk, and create a platform for future growth.
Control System Upgrade FAQs
What is a control system upgrade?
A control system upgrade is the process of replacing or modernising outdated automation hardware and software to improve reliability, safety, and performance.
It helps industrial systems remain supportable, efficient, and compatible with current operational requirements.
When should you upgrade a control system?
A control system should be upgraded when hardware becomes obsolete, faults become more frequent, or spare parts are difficult to source.
Upgrades are also needed when systems can no longer support production, reporting, or safety requirements.
Can control systems be upgraded without stopping production?
Yes, many upgrades can be completed using phased migration and parallel testing to minimise disruption to live operations.
