Title:
NETWORK INFRASTRUCTURE FOR MOBILE MACHINES WHICH CAN BE USED IN AREAS AT RISK OF EXPLOSION
Document Type and Number:
WIPO Patent Application WO/2011/110983
Kind Code:
A1
Abstract:
The invention relates to a network infrastructure for mobile machines which are usable in explosive areas, having inherently safe participants 21 - 23 and not inherently safe network participants 31 - 33 the latter being arranged in pressure-resistant housings 7; 8. The machine has at least one controller 30 for actuating at least one not inherently safe participant 31. In order to provide a network infrastructure which avoids the drawbacks of the prior art, the machine has, outside the pressure-resistant housing 8 for the first controller 30, at least one second, inherently safe controller 20 for actuating at least one inherently safe participant 21, wherein the first controller 30 forms a data distributor for a plurality of not inherently safe participants 31 - 33 and the second controller 20 forms a data distributor for a plurality of inherently safe participants 21 - 23, and wherein the first data distributor 30 and the second data distributor 20 are linked via an electrically decoupled data communication link 40.
