OTee

Your control systems still run on proprietary PLCs designed before connectivity, cybersecurity, and fleet-scale operations were requirements. OTee replaces them with software-defined control you can deploy on standard hardware and manage centrally across every site.

Most operators run a mix of Rockwell, Siemens, Schneider, ABB, and other vendor PLCs — each with its own tools, its own lifecycle, and its own €2,500+ price tag per controller. Every change means local access or a truck roll. Upgrades mean hardware replacement on a 5–10 year cycle. And connectivity bolted on after the fact creates data loss and security gaps.

OTee runs an IEC 61131-3 virtual PLC on off-the-shelf x86/ARM Linux hardware — a €200–600 device that’s ~3x faster than a proprietary controller at a fraction of the price — engineered in a browser-based IDE and managed as a fleet from one place. Build a virtual PLC in minutes; deploy and manage thousands across sites.

In production deployments this has meant:

• ~50% lower hardware CAPEX and ~75% lower PLC management OPEX at a water utility running 200+ pump stations

• Zero data loss through local buffering, with 455x better data resolution versus the legacy controllers it replaced

• USD 134k in annual savings at a thermal energy facility through 100% remote, automated load optimization — with zero on-site reprogramming

OTee has been live in 24/7 mission-critical operations since October 2024, is benchmarked against leading PLCs, and is in use across 70+ countries. Customers include Aker BP, Scania, Hafslund, Verbund, and Nordic Electrofuel.
