A method for searching a slave - node in a communication network, master - node and slave - node for a communication network

摘要

It is a method for searching for an identifier (uid) or sub identification of a slave - node (130, 150, 170; 130 '', 150'', 170 '') in a communication network (100) is described, whereby the communication network - a master node (110) and one or more slave - node (130, 150, 170), via a communications link (102) are connected to one another, wherein each slave - node has a memory in that a multi-digit code (uid) is stored a clear identification of the slave - node in the communication network is enabled, wherein each location, a predetermined value; the process comprises the steps of: defining (412, 422) a point of the identifier (uid) or sub identification by means of an index (idptr) in the master - node, and in the slave - node or in any one of the plurality of slave - node; sending (414) of a first test command (dip0) of the master - node to the slave - node or to the plurality of slave - node, wherein the first test construction on the by the index (idptr) defined point of the identifier (uid) or sub identification to be tested, a first value ("0"); comparing the first value to be tested ("0") with a value (uid [idptr]) on which, by the index (idptr) defined location of its own identifier (uid) or sub identification in the slave - node or in the plurality of slave - node; sending a confirmation signal (irq) of the slave - node or a (130, 130'') of the plurality of slave - node if the comparison shows that ..
