OpenPowerlink over Xenomai
Industrial Ethernet is a successor of classic field bus such as CAN, MODBUS or PROFIBUS. POWERLINK was created by B&R Automation and provides performance and realtime capabilities based on standard Ethernet hardware. openPOWERLINK is open source and runs on lots of platforms such as Linux, Windows, various RTOS and dedicated hardware (FPGA). We will explain how to use openPOWERLINK on top of Xenomai 3, a powerful realtime extension for Linux kernel based on co-kernel technology.
Current version of openPOWERLINK runs on Linux with (or without) PREEMPR_RT patch.
Xenomai is an alternative to PREEMPT_RT. It's not a single patch for the Linux kernel but runs as a dual kernel (Linux and Cobalt) on top of a micro-kernel (ADEOS/I-pipe).
This is the 2nd version of conference about openPOWERLINK/Xenomai as the port works now on the famous BeagleBone Black board running Linux (Buildroot based distro) or Android.
This presentation will introduce openPOWERLINK as an alternate - and open source - solution to proprietary products such as EtherCAT.
We will introduce Xenomai and explain how to integrate the openPOWERLINK stack with Xenomai 3.0. Finally we will compare Xenomai and PREEMPT_RT version running on the same hardware.
