| 摘要 |
<p>The invention relates to a system of at least two physical state-blocks (2), wherein each state-block comprises an identification stored in a state-block memory (18), a processing unit (16), one communication port (22) for communicating identification and state-information to and from said state-block. The state-block also comprises a state port (20) for applying and/or for indicating state changes. The identification for all state-blocks in said system belongs to the same identification family and that the identifications of the other state-blocks in the family are stored in the state-block memory of each state-block. A state change applied at the state port of one state-block in the system is communicated via said communication port to all other state-blocks in the family and is indicated at the state port of said other state-blocks.</p> |
