Legacy Control System Modernization

Upgrade obsolete PLCs, HMIs, and SCADA — without starting over or shutting your plant down.

When a control system reaches end of life, every day on it adds risk: spare parts dry up, the people who programmed it move on, and a single failure can idle a line for days. Industrial Control Systems modernizes aging automation on your schedule — migrating to current, supportable platforms with a phased plan that protects uptime and keeps your process running the way your operators expect.

We’ve migrated Allen-Bradley PLC-5 and SLC-500 systems to ControlLogix, replaced obsolete HMI/SCADA with Ignition and FactoryTalk, and rebuilt documentation for systems nobody had drawings for. Most cutovers are staged around your production windows so the line keeps moving.

What we modernize

  • ✓  PLC migrations — PLC-5 & SLC-500 to ControlLogix / CompactLogix
  • ✓  Legacy HMI & SCADA to Ignition or FactoryTalk View
  • ✓  Obsolete networks (DH+, ControlNet, DeviceNet) to EtherNet/IP
  • ✓  Aging drives, I/O, and panel hardware brought to current standards
  • ✓  Windows, server, and OS upgrades for SCADA and historians
  • ✓  Historian and data migration with no loss of history
  • ✓  Drawing and documentation recreation for undocumented systems
  • ✓  Obsolescence assessments and phased migration roadmaps

Why modernize with ICS

We’re platform-certified where it counts — Rockwell Automation, Inductive Automation (Ignition), Sepasoft, and AVEVA — so we move you to the right system, not just a familiar one. With 28+ years and 2,500+ projects behind us, we plan migrations that minimize downtime, preserve your process knowledge, and leave you with clean documentation and a system your own team can support.

Facing an obsolete system or planning an upgrade? Let’s map a migration path that fits your production schedule.
