Proposal and evaluation of deterministic access in KNX standard
Salvatore Cavalieri, Giovanni Cutuli · 2008
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 real-time 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 itpsilas full compliance with the KNX standard.
