Method and control and data-transmission system for checking the installation location of a safety communications component
First Claim
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 (30), a first configuration dataset which contains information on the position of all of the connected components with respect to the control and data-transmission system (10) and an individual position identifier for each safety component (60);
storing, in the safety control device (50), a second configuration dataset which contains a list of only the connected safety components and also an individual position identifier for each safety component;
transmitting, in a first communications cycle, each individual position identifier from the non-safety communications control device (30) to each safety component (60);
transmitting the individual position identifiers contained in the second configuration dataset, in safety messages from the safety control device (50) to the non-safety communications control device (30);
transmitting, in a second communications cycle, the individual position identifiers contained in the received safety messages, from the non-safety communications control device (30) to the corresponding safety components (60);
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 (50), that the corresponding safety component is connected at the predetermined installation location.

Abstract
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 data-transmission 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).
