MaxRT wRTOS™ 1.0 is now available!
Real-time Software for PC-Based Industrial Control Systems
Industrial Control Systems are shifting to open, PC‑based platforms as machines must become cloud‑connected, remotely managed, and AI‑enabled. IntervalZero provides the most open, standards-based, real‑time software foundation for this transition — transforming standard industrial PCs into deterministic, secure, AI- & IoT‑ready control systems. MaxRT and RTX64 power high‑performance machines across automation, medical, automotive, defense, and more industries.
CRA Compliance Starts with MaxRT — and Leads to Software‑Defined Architectures
The Cyber Resilience Act is forcing machine builders to modernize. CRA compliance requires open standards, transparent software, and an Industrial PC platform — not proprietary controllers. MaxRT is the fastest path to that foundation, delivering deterministic real‑time performance on a secure, standards‑based IPC.
This shift sets the stage for the next step: Software‑Defined Architectures, where control applications can be deployed, updated, and managed with far greater agility. MaxRT — and the upcoming MaxRT vRTOS — are the on‑ramps to that future.
MaxRT, the new real-time solutions to address the next generation of Industrial Control Systems
MaxRT introduces two distinct products to meet diverse deployment needs:
- MaxRT wRTOS™: The next generation of RTX64, delivering unparalleled real-time capabilities for Windows.
- MaxRT vRTOS: A real-time hypervisor solution compatible with MaxRT wRTOS™ that can be deployed with a general-purpose operating system (GPOS) front-end like Windows or Linux, enhancing cybersecurity and flexibility.
RTX64 Transforms Windows into the RTOS Platform for Building Industrial Control Systems
IntervalZero’s RTX64 real-time software complements Windows for building next generation of Industrial Control Systems. Its symmetric multiprocessing (SMP) capabilities brings scalability to system designers and native 64 bits support complies with new market memory requirements. All Windows libraires, drivers and tools are available.
RTX64 has been designed for embracing standards such as Windows, Visual Studio, TSN, EtherCAT, OPC UA and more. It’s a guarantee for our customers to protect their investment and to be always ready to access to new technologies.
Standards Protect the Machine Builder
IntervalZero is committed to open standards and tools (Windows, Visual Studio, RTX64 RTOS, C++, EtherCAT, TSN, OPC-UA) which protects our customers’ investment and to IoT-readiness that ensure the machine builder can support any future cloud connectivity demands. The RTOS Platform serves as an integration environment. The modularity and customizability ease the burden of integrating multiple controllers. Some forward-thinking machine builders are even consolidating multiple controllers onto a single PC.
