Abstract
A network infrastructure for mobile machines which are usable in explosive areas, having inherently safe participants and not inherently safe network participants the latter being arranged in pressure-resistant housings. The machine has at least one controller for actuating at least one not inherently safe participant. In order to provide a network infrastructure which avoids the drawbacks of the prior art, the machine has, outside the pressure-resistant housing for the first controller, at least one second, inherently safe controller for actuating at least one inherently safe participant, wherein the first controller forms a data distributor for a plurality of not inherently safe participants and the second controller forms a data distributor for a plurality of inherently safe participants, and wherein the first data distributor and the second data distributor are linked via an electrically decoupled data communication link.
