1. A communication system (KS) comprising a communication bus (KB), a master device (MD) which is connected to the communication bus and which communicates with the communication bus (KB) in a master mode, and several slave devices (SD1, SD2 . . . SDn) which can be connected to the communication bus (KB) and which communicate with the communication bus (KB) in a slave mode,
wherein the slave devices (SD1, SD2 . . . SDn) can be connected by means of a communication module (KM) designed as a proxy to the communication bus (KB), wherein the communication module (KM) is connected by means of an input port (EP1) to the communication bus (KB), and has output ports (AP1, AP2 . . . APn) for the connection of the slave devices (SD1, SD2 . . . SDn) by a point-to-point connection, in that the communication module (KM) has a communication processor (KP), which is connected on the input side to the communication bus (KB) and on the output side to a first internal bus (IB1) by means of a first serial interface (SI1), wherein each of the output ports (AP1, AP2 . . . APn) is connected to the first internal bus (IB1) in each case by means of a first switchable transceiver (TR1.1, TR1.2 . . . TR1.n), wherein the communication processor (KP) has an association table (ZZT) with data pertaining to the association of destination addresses with output ports (AP1, AP2 . . . APn), communication parameters and/or slave device addresses, wherein incoming message frames can be analyzed with regard to their destination address and forwarded, taking into consideration the data of the association table (ZZT), to one of the output ports (AP1, AP2 . . . APn) using the associated communication parameters for the slave device (SD1, SD2 . . . SDn) connected to the output port (AP). |
