Service overview
Engineering plc / dcs control systems
PLC / DCS modernisation — code-level migration, simulation-first rollout, parallel runs, signed firmware, zero unplanned downtime. Siemens S7 / TIA, Allen-Bradley Logix, Schneider Modicon, ABB 800xA. Brownfield modernised without brownfield surprises.
Industrial control engineers + software engineers, on the same backlog. That's an unusual combination; we've found it's the only one that survives a plant audit.

Business challenges we solve
What keeps teams shipping plc / dcs control systems.
PLC programs from 2008 still in production
Brownfield migration downtime creeping up
Shadow logic in spreadsheets and tribal knowledge
Cybersecurity gaps exposed at recent audit
TI Portal / Studio 5000 upgrades failed because no simulation
Plant operators confused by new screens
Why choose this service
Three senior-led practice lines.
Outcome-anchored, owned by a practice lead with clear accountability, weekly demos, and the kind of code review culture you'd build internally if you had a year.
