700/81

A method and also a control and data-transmission system is presented, with which the installation location of at least one safety bus component connected to the control and datatransmission system (10) can be checked.

For this purpose, in two separate communications cycles, a respective position identifier, which had been allocated to the safety bus components (60) in a prior configuration process, is transmitted to each safety bus component via a non-safety communications control device (30). The safety bus components compare the position identifiers received in the two communications cycles to the contents of a memory, in which a reference position identifier has already been stored or which is still empty. Based on a comparison of the transmitted position identifier to the reference position identifier and the configuration dataset stored in a safety control device (50), it can be tested whether each safety bus component is connected to the predetermined installation location within the control and data-transmission system (10).
