IEC 61131-3 automation software for industrial controllers and IIoT systems

Software Development Kempten, Bayern 51–200 employees Founded 1994 Public Company

CODESYS Group manufactures IEC 61131-3 compliant automation software serving controller makers and industrial system integrators worldwide. The tech stack reveals a dual-layer architecture: embedded control (C, IEC 61131-3 compilers, PROFINET/Modbus/OPC UA) paired with modern web frontends (TypeScript, Angular, .NET). Active projects cluster around cloud connectivity (remote device management, controller-cloud protocols) and web-based tooling (CODESYS Go!), signaling a shift from desktop-centric engineering toward cloud-native and browser-based development environments—a major modernization for a 30-year-old automation platform.
