Upgrade obsolete hardware, eliminate downtime risks, and modernize your production line without losing your legacy logic.
Running a facility on unsupported, end-of-life control systems is a massive operational risk. When a critical legacy component fails, sourcing a replacement can take weeks, resulting in catastrophic downtime. VRX Industrial specializes in seamless control system migrations. We help manufacturers transition from obsolete platforms to modern, supported architecture (such as Allen-Bradley ControlLogix, Siemens S7, and Omron NX/NJ series). By managing both the hardware procurement and the engineering integration, we ensure a smooth, rapid upgrade with minimal disruption to your production schedule.
Our Migration & Retrofit Capabilities
- Turn-Key PLC Conversions: We safely extract and convert legacy ladder logic and code into modern programming environments, ensuring your machine operates exactly as intended on the new hardware.
- HMI & SCADA Upgrades: Replace failing CRT screens and outdated push-button panels with high-resolution, responsive touchscreens. We rebuild interfaces to improve operator visibility and data logging capabilities.
- Servo & Drive Modernization: Swap out obsolete DC drives and aging amplifiers for highly efficient AC VFDs and modern servo systems, directly improving machine precision and energy efficiency.
- Industrial Network Upgrades: Transition from vulnerable proprietary networks (like Data Highway Plus or Profibus) to robust, high-speed Ethernet/IP or Profinet infrastructure.
The VRX Migration Process
We approach every retrofit strategically to ensure zero loss of functionality:
- Phase 1: Hardware Audit & Risk Assessment. Our engineers evaluate your existing panel, document the current I/O, and identify the most at-risk components.
- Phase 2: Code Extraction & Procurement. We pull the existing logic for conversion while simultaneously securing all necessary replacement PLCs, modules, and drives from our extensive distribution network.
- Phase 3: Panel Build & Bench Testing. When possible, we build and wire the new backplates in our facility, bench-testing the logic prior to deployment to minimize on-site commissioning time.
- Phase 4: Installation & Commissioning. We coordinate the physical swap during scheduled facility downtime, powering up the system, verifying all I/O, and validating machine performance alongside your operators.
