Proposal and Evaluation of Deterministic Access in KNX Standard

This proposal is about the real-time requirements of control processes. This proposal also analyzes the capability of the KNX home and building automation standard to meet deterministic access. The paper proposes a solution to give deterministic bus access to the KNX devices. The proposal is based on the Master/Slave configuration network. In this configuration only one node, called Master, manage all the available bandwidth between the other devices, called Slaves. The Master accepts the entire realtime communication requirement from the slaves and once it knows them can start its internal scheduling algorithm in order to distribute the available bandwidth to the slaves. A key point of the proposed approach is that it's full compliance with the KNX standard. © 2008 IEEE.
