Abstract:
1. Method for checking the installation location of at least one safety component ( 60 ) connected to a control and data-transmission system ( 10 ), wherein a non-safety communications control device ( 30 ), to which a safety control device ( 50 ) is allocated, is connected to the control and data-transmission system, wherein the non-safety communications control device ( 30 ) recognizes the position of each connected component in the control and data-transmission system ( 10 ), the method comprising: storing, in the non-safety communications control device ( storing, in the safety control device ( transmitting, in a first communications cycle, each individual position identifier from the non-safety communications control device ( transmitting the individual position identifiers contained in the second configuration dataset, in safety messages from the safety control device ( transmitting, in a second communications cycle, the individual position identifiers contained in the received safety messages, from the non-safety communications control device ( comparing, at each safety component, the individual position identifiers received in the first and second communications cycles; if a safety component determines that the individual position identifiers match, testing whether a reference position identifier is stored in the corresponding safety component; if a reference position identifier is stored in the corresponding safety component, comparing the individual position identifier to the reference position identifier; and if the individual position identifier matches the stored reference position identifier of the corresponding safety component, signaling, via the safety control device (
