Sercos introduces Sercos-on-a-Stick live demo system

Summary

December 1, 2017 - With the Sercos-on-a-Stick live demo system, Sercos International, in cooperation with Bosch Rexroth and TenAsys, offers a means to evaluate the Sercos SoftMaster. Within minutes, Sercos-on-a-Stick converts almost every x86 based PC to a Sercos Master Test System, making it possible to realize real-time communication without hardware extensions. Using a Time-Triggered-Send (TTS) enabled Ethernet controller (Intel i210 or Texas Instruments PRU-ICSS), the requirements of motion applications are met. The system uses the TenAsys INtime multicore real-time operating system, which serves as the basis for future-proof control solutions.

For this purpose, the INtime Distributed RTOS has been configured to serve the Sercos Master as a royalty-free and time-limited test platform. The Sercos-on-a-Stick live system is designed such that no changes to the target platform are made and therefore a backup of the target system is not required. The live system runs on any machine that meets the following hardware requirements: x86 architecture, 2 free USB ports for the USB flash drive and a keyboard, an Intel, Broadcom or Realtek Ethernet controller, a screen as a console and the bootability of USB. Apart from CPU, memory and the aforementioned components, no other hardware is used on the target platform.

The live system is provided as an image, which is transferred to a sufficiently large USB flash drive using a freely available software tool.

The target platform is started via USB boot with this application. The boot loader first generates a RAM disk and then loads a system image consisting of INtime RTOS and the Sercos application into a RAM disk. When the INtime instance is started on the RAM disk, the Sercos-on-a-Stick application is started.

To work with as many target platforms as possible, the live system supports both traditional and newer Ethernet controllers (such as Intel i210) that support timed transmission of Ethernet telegrams according to the new Ethernet TSN standard.
