1. An input/output module (I/O Module) that is part of a modular fieldbus node that includes a head station, the I/O module comprising:
a housing to establish a frictional or form-fitting connection connect between the I/O module and a housing of a first module, the first module being another I/O module of the modular fieldbus node or the head station of the modular fieldbus node;
an interface configured to communicate with the first module; and
a memory,
wherein the I/O module is set up to receive data directly from the first module via the interface and store the data in the memory, the data including information regarding a configuration of the first module, and
wherein the I/O module is set up to transmit the information directly to a second module upon request, and
wherein the I/O module is set up to transmit the information to the second module if the I/O module determines that the second module replaces the first module.
