Legacy Controls Systems
Allen-Bradley: Old School Meets New School
If you’ve ever seen an Allen-Bradley SLC-500, you know the feeling: a little box of mystery, full of blinking lights and ladder logic that’s stood the test of decades. At Castor Engineering, moments like these make us grin. We’ve spent countless hours in RSLogix500, untangling legacy logic, updating firmware, or just marveling at how rock-solid these systems still are. And when a plant says, “We’ve got a ControlLogix stack we need integrated into a new MES,” our eyes light up. Think this is difficult to service? Think again
Allen-Bradley isn’t just history, it’s the foundation for modern automation.
Siemens
Siemens, Because Variety is the Spice of Life
When a project requires a mechanical system, our engineers jump into SolidWorks, creating everything from conveyor assemblies to custom tooling. We enjoy tackling the challenges of motion envelopes, clearances, and part interactions long before any fabrication begins. It’s like building a playground in 3D—except the swings have actuators, sensors, and safety interlocks.
Digital Twins
Robotics and Digital Twins
We don’t stop at one ecosystem. Siemens systems are also a playground for our engineers. From S7-300 and S7-1500 PLCs to WinCC HMIs and TIA Portal projects, we enjoy bridging Siemens solutions into multi-vendor environments. It’s like solving a puzzle where every piece has a different brand logo, but when it all clicks together, the factory hums like a finely tuned engine
Manufacturing Automation SOlutions
Controls at the Core
Even when our Smart Manufacturing Solutions team is talking enterprise software (MES, ERP, analytics) controls are never far away. They’re the underlying story, the real-time signals that drive insights, efficiency, and decisions. We design systems that take the raw, honest data from the shop floor, discrete inputs, analog measurements, batch events, and turn it into actionable intelligence for operators, supervisors, and executives. Controls form the bridge between machines and minds, and we love engineering that connect
Why Castor Engineering
Fun Meets Function
This isn’t just about code and wiring, it’s about curiosity and creativity. We get excited by weird, old systems that still run like champions. We appreciate the elegance of a perfectly designed ladder routine. We laugh at the quirks of legacy HMI screens that were “modern” twenty years ago. And we get fired up when we integrate these machines into modern dashboards that would have seemed impossible to the engineers who wired them in the first place.
