The invention relates to a redundantly designed arrangement which passes through a test and configuration phase before the actual operation. For this purpose, it exhibits a number of test modules (3) connected to one another via a serial test bus (5), which modules test themselves in the initial test phase. They are also responsible for testing the test bus (5), a system bus (6) connecting the system modules (1), and crossbar distributors (2, 2a). For the system to operate, the required modules and bus lines operating correctly are connected together and the remaining ones are disconnected. <IMAGE>
