Cyberphysical Product Dev using Industrial Linux Servers – Aircraft Case Study

For most complex systems producers, cyberphysical product development is a portion of a sophisticated Model Based Systems Engineering (MBSE) product development strategy and set of processes.

Understanding the Real-Time Executive Daemon (rtxd) for Linux

The real-time executive daemon, or the “rtxd”, is a set of Linux processes and Linux process APIs providing a high-resolution computing time reference, a shared memory data management architecture, and a comprehensive set of computing services for real-time and accelerated industrial computing applications.  The rtxd transforms the standard Linux computing environment into a microsecond resolution, highly instrumented, distributed computing, client-server platform.

Industrial Real-Time Linux Servers

An Industrial real-time Linux server is a computer server, low-cost or very high-end, with a real-time Linux operating system installed and providing a set of services for time-deterministic, frequency-based, cyberphysical computing and data handling. This real-time Linux server is used to connect your industrial capability, e.g. test facility, manufacturing line, prototype system, into a Linux computing environment for the purpose of adding capability, e.g. machine learning, HIL simulation, live analytics, rapid prototype control, supervisory control, data acquisition.
