ASI network for explosion-hazard areas
First Claim
1. A fieldbus system, comprising:
- a plurality of bus line sections with bus lines;
isolating elements, each coupling two of the plurality of bus line sections to one another, to galvanically isolate the bus lines of the two bus line sections from one another such that any direct current is prevented from flowing between the bus lines of the two bus line sections and such that transmission of communication signals is permitted between the two bus line sections; and
a supply source for each of the bus line sections, to provide an electrical power supply for field devices connectable to a respective bus line section, a plurality of the bus line sections being connected, via isolating elements, to form a series circuit.

Abstract
At least one embodiment of the invention relates to a fieldbus system, in particular for use in an explosion-hazard area. The fieldbus system, in at least one embodiment, has a plurality of bus line sections with bus lines; an isolating element, by which in each case two of the plurality of bus line sections are coupled to one another and which galvanically isolates the bus lines of the two bus line sections from one another such that this prevents any direct current flowing between the bus lines of the two bus line sections and communication signals are transmitted between the two bus line sections; and a supply source for each of the bus line sections, in order to provide an electrical power supply for field devices which can be connected to the respective bus line section.
