MaxRT eRTOS

MaxRT eRTOS is a standalone, embedded Real-Time Operating System (RTOS) designed for PC-based industrial control systems. It enables deterministic, high-speed execution of real-time applications without relying on Windows. Built on the RTX64 foundation, it supports multi-core processing and is ideal for headless systems with remote HMIs.

Features

• Real-Time Precision: Timer periods down to 1 microsecond; IST latencies under 3–10 microseconds.
• Symmetric Multiprocessing (SMP): Supports up to 64 processors with a unified scheduler.
• Memory Access: Direct access to up to 512GB of physical memory.
• Thread Control: Configurable thread and interrupt affinities; load balancing support.
• Development Environment: Compatible with Visual Studio 2019 and 2022; supports C/C++.
• Hardware Access: No driver model required—real-time processes can directly access hardware.
• Networking & Interfaces: Includes TSN-based real-time networking and OPC UA support.

Capabilities

• Deterministic Execution: Ensures consistent, predictable response times for critical applications.
• Scalability: Efficiently scales from 1 to 64 cores, making it suitable for a wide range of embedded systems.
• Inter-Process Communication: Uses standard IPC mechanisms (events, mutexes, semaphores) and shared memory.
• Headless Operation: Designed for systems without local displays; HMI runs remotely.

Benefits

• Cost Efficiency: Eliminates the need for proprietary controllers and reduces hardware costs.
• Simplified Development: Uses standard tools and languages, reducing learning curves and development time.
• Improved Asset Utilization: Leverages underused multi-core capacity in industrial PCs.
• Maintenance & Upgrades: Enables software-based field upgrades, reducing downtime and inventory needs.
• Compatibility: Source code compatible with other MaxRT editions (wRTOS, vRTOS), supporting flexible deployment strategies.
