    摘要： The error-free function of modules in a bus system with a central unit is tested. First, all (error-free) modules are set into a silent operating mode in response to an agreed silence-command, and then in this silent operating mode it is tested whether all modules still remain silent, i.e. do not transmit data, in response to an agreed data request allocated to these modules. A module that nonetheless transmits data is recognized as faulty and is deactivated. Subsequently, all modules except for a module to be tested are set into the silent operating mode, and then it is tested whether this test module transmits its data in response to the agreed data requests allocated to it and remains silent in response to the data requests not allocated to it. Additionally, the position of the return-transmitted data can be determined and compared with a nominal position.

    摘要： The invention relates to a method for the testing of the error-free function of modules in a bus system with a central unit as well as suitable modules, a corresponding central unit and a corresponding bus system. For this purpose, an especially agreed-upon silence-command is provided, in response to which the modules in the error-free condition switch into a silent operating mode, and also expressly transmit no data particularly in response to the data requests allocated to the modules. By means of this silence-command, at first all modules can be set into the silent operating mode, and then by means of the agreed data request it can be tested whether all modules still switch into the silent operating mode. A module that nonetheless still transmits is recognized as faulty and is, for example, deactivated. Subsequently, respectively all modules except for a module to be tested are set into the silent operating mode, and by means of data requests agreed-upon for this module to be tested and/or not agreed-upon for this module it is tested whether the module transmits its data in response to the agreed data request(s) and remains silent in response to the not-agreed data requests. Additionally, the position of the return-transmitted data can be determined and compared with a nominal or desired position, which is not possible as a rule in the normal operation.

    摘要： A bus station addressable using at least one group address is provided. For the evaluation of the group addresses, the bus station has a decoder for converting a group address received via the bus into a decimal group address, a register in which the permissible group addresses are stored as a register word, and a logic circuit for the comparison of the decoding word and the register word. The logic circuit generates an enabling signal for the bus station, as a function of the comparison.
