Claim:
A network infrastructure for one or more mobile machines which are usable in areas at risk of explosion, each mobile machine comprising one or more inherently safe participants and one or more not inherently safe participants which are arranged in pressure-resistant housings, wherein the network infrastructure comprises: at least one first controller, arranged in a pressure-resistant housing, configured to actuate the one or more not inherently safe participants of a first mobile machine of the one or more mobile machines; and at least one second controller disposed outside of the pressure-resistant housing for the at least one first controller and configured to actuate the one or more inherently safe participants of the first mobile machine; wherein the at least one first controller forms a first data distributor for the one or more not inherently safe participants and the at least one second controller forms a second data distributor for the one or more inherently safe participants; wherein the first data distributor and the second data distributor have an electrically decoupled data communication link between them; and wherein the at least one first controller and the at least one second controller are both mounted within or on the first mobile machine and configured to be operated within the areas at risk of explosion.
