PBMaster is a software implementation of Profibus protocol (IEC 61158) compatible master node. The objective is to provide open implementation for education, experiments, enthusiasts and also to open way to its use in low-cost applications by using common hardware and open-source software. For documentation see http://pbmaster.sourceforge.net/ .
Containment Domains are a framework for computational resiliency
...Containment Domains (CDs) were created to allow an application to recover in the face of various types of component failures, including hard (e.g. persistent) and soft (e.g. transient) hardware failures, transient software failures, and complete node failures.
