ABSTRACT:
For assembly substitution actions during ongoing operation of a bus system, effects can occur that lead to oxidation of connecting contacts, to the destruction of assembly components or to the disturbance of bus signals because of the transmission of electrical energy via the connecting contacts of plug-type connectors (SP1 . . . SPn) of the assemblies (BG1 . . . BGn) when inserting or removing an assembly. Since bus signals can also be disturbed when the supply voltage is disconnected before the assembly substitution action, the bus system is inhibited before an assembly substitution action. After the conclusion of the assembly substitution action, the assemblies affected by the assembly substitution action are selectively reinitialized.
