Free Sercos SoftMaster now available in a ready-to-run package

The Sercos SoftMaster is a software-based Sercos® Industrial Ethernet master that is implemented on standard industrial-PC hardware (X86 or ARM) with a variety of operating systems supported. Dedicated hardware is not required, providing cost savings in many applications.

Bosch Rexroth has made the Sercos SoftMaster available as free open source software. They also offer a free Sercos-on-a-Stick livesystem--a complete stand-alone demo Sercos driver package on a USB thumb drive. This includes the SoftMaster based on INtime® Distributed RTOS from TenAsys Corporation, and a test application. This is the Sercans XS package.

The featured solution is scalable:

The familiar Sercos HardMaster solutions are still available for all applications with higher bus cycle time requirements, or for which the hardware and operating system platform requirements cannot be met.

Using the generic mode, virtually every Ethernet controller is suitable for use with the Sercos SoftMaster. However, the telegram jitter reduces the synchronization accuracy. For higher synchronicity and cycle time requirements, the NIC/TTS mode (as with Intel I210) is available. Here, the Ethernet controller (NIC) precisely determines the telegram transmission using its own timer. Software-based timing disturbances (jitter) are eliminated as programs must only ensure that telegram content is fed to the Etherrnet controller within the time window provided.
