Assembly having an interface module and the interface module
2004
Arrangement with at least two communication modules (200, 301-305) and an interface module (500) wherein the at least two communication modules (200, 301-305) each include a communication interface element (212) contained wherein the interface module (500) (CIS) and an output (COS) has an input and the respective communication interface element (212) in each case, a message memory (202) de communication module (200, 301-305) is associated with the at least two communication modules (200, 301-305), each having a data bus (211, are connected 320-325), wherein a respective first data path (V27) to and from the data bus (211, 320-325) as well as to and from the respective message memory (202) is provided, via which first data and / or messages to and from the respective message memory (202 are passed) wherein the respective communication interface element (212) provides a respective additional second data path (V28-V31) which is designed such that the first data and / or messages of the first data path (V27) at least partially via the additional second data path (V28-V31) be conducted wherein the at least two communication modules (200, 301-305) via the second data path (V28-V31) are connected together and the interface module (500) via the input (CIS) and the output (COS) in this second data path (V28-V31) is switched such that an annular interconnection of the at least two communication modules (200, 301-305) and the interface module (500) results, wherein in said interface module (500), a first transmission path (V51) and a second transmission path (V52, V53, V54) are provided with a coupling element (501) and a switching means (503) is present which is designed such that the first transmission path (V51) and the second transmission path (V52, V53, V54) of the interface module to the output (COS) to be interconnected.
