The configuration has a connection housing with an inlet, an outlet, and a connection opening for connection of an exchangeable functional unit. The connection housing has a rotatably arranged core piece whose rotation makes it possible for the throughflow of the fluid through the connection housing to be blocked and/or released. The core piece has a receptacle for connection of the functional unit, and the receptacle and the connection opening are oriented in the same direction. ## Claims ### Claim 1 A configuration for installation into a pipeline of a fluid network, the configuration comprising: an exchangeable functional unit; a connection housing having an inlet, an outlet, and a connection opening formed therein for connection to said exchangeable functional unit; and a core piece rotatably disposed in said connection housing, a rotation of said core piece makes it possible for a throughflow of a fluid through said connection housing to be blocked or released, said core piece having a receptacle for connection of said exchangeable functional unit, said receptacle and said connection opening are oriented in a same direction. ### Claim 2 (depends on 1) The configuration according to claim 1, wherein said inlet and said outlet are disposed along a throughflow axis, and a direction of connection of said exchangeable functional unit runs substantially orthogonally with respect to the throughflow axis. ### Claim 3 (depends on 1) The configuration according to claim 1, wherein said core piece has a core piece inlet and a core piece outlet disposed opposite said core piece inlet. ### Claim 4 (depends on 3) The configuration according to claim 3, wherein said core piece inlet and said core piece outlet are in each case connected to said receptacle. ### Claim 5 (depends on 3) The configuration according to claim 3, wherein by rotating said core piece inside said connection housing, said inlet and said outlet of said connection housing, and said core piece inlet and said core piece outlet of said core piece, are able to be brought into fluidic connection. ### Claim 6 (depends on 1) The configuration according to claim 1, wherein said core piece is inserted into said connection opening. ### Claim 7 (depends on 1) The configuration according to claim 1, further comprising a sealing element for sealing off said connection housing with respect to said core piece, said sealing element is disposed in a region of said inlet and/or said outlet. ### Claim 8 (depends on 7) The configuration according to claim 7, wherein said sealing element has a first seal which acts radially, against said connection housing, and a second seal which acts axially, against said core piece. ### Claim 9 (depends on 3) The configuration according to claim 3, wherein said exchangeable functional unit has a holder, said core piece is rotatably fixed to said connection housing by said holder. ### Claim 10 (depends on 9) The configuration according to claim 9, wherein said exchangeable functional unit is connected to said receptacle, and a rotation of said core piece is realized by a rotation of said exchangeable functional unit connected to said receptacle. ### Claim 11 (depends on 10) The configuration according to claim 10, wherein said exchangeable functional unit is able to be locked in at least one rotational position. ### Claim 12 (depends on 10) The configuration according to claim 10, wherein said exchangeable functional unit and said connection housing and/or said holder have devices for establishing a mechanically releasable connection between said exchangeable functional unit and said connection housing and/or said holder. ### Claim 13 (depends on 12) The configuration according to claim 12, further comprising projections disposed on said exchangeable functional unit as said devices for establishing a mechanically releasable connection and engage into corresponding recesses of said connection housing and/or of said holder. ### Claim 14 (depends on 12) The configuration according to claim 12, wherein said devices for establishing a mechanically releasable connection include a bayonet closure. ### Claim 15 (depends on 10) The configuration according to claim 10, wherein said exchangeable functional unit has a throughflow channel which, in a connected state, is situated inside said core piece and is connected to said core piece inlet and said core piece outlet. ### Claim 16 (depends on 10) The configuration according to claim 10, wherein said exchangeable functional unit is selected from the group consisting of a placeholder functional unit, a descaling functional unit, a filtering functional unit, a pressure reduction functional unit, a monitoring functional unit, a germ reduction functional unit, a functional unit for determining chemical and microbiological parameters, a functional unit for determining pH, electrical conductivity, nitrate, nitrite, sulphate, carbon dioxide, iron, fluoride, chlorine, copper, phosphate, silicon, ammonium, hardness, temperature, throughflow rate, carbonate, salinity, germ content or metal content, data functional unit, a communication functional unit, a display functional unit and a function unit performing a combination of these recited units. ### Claim 17 (depends on 10) The configuration according to claim 10, wherein said exchangeable functional unit has a seal which seals off said exchangeable functional unit with respect to said core piece. ### Claim 18 (depends on 10) The configuration according to claim 10, wherein said exchangeable functional unit has its own connection geometry.
