Abstract

An arrangement in which at least one master unit is linked via a bus to a multiple of slave units, each slave unit having a memory in which the master unit carries out read and/or write accesses. The master unit can initiate a data access uniformly on each of the slave units according to a predetermined communication protocol. Moreover, a slave unit is proposed which is suitable for a communication with a master unit according to this protocol. The arrangement can be used in programmable controllers.
