Abstract
Abstract An automatic determination of an address suitable for a functional unit connected to other similar functional units via a bidirectional communication network. A field of possible addresses are scanned and a status request is transmitted for each address. In response to the request, if an answer is received, this means the address is already allocated, the address is incremented and the process is restarted. If no answer is received, then a second test is performed on the same address. If there is still no answer, meaning the address is available and not taken by another functional unit, the address is adopted.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
152 words
A process for matching a plurality of functional units connected together via a bidirectional communication space, each of said plurality of functional units being provided with remote control means and indicating means, some of said plurality of functional units being provided with matching means, said process comprising: a) designation by an operator of a control functional unit by actuating matching means of said control functional unit; b) activation of said indicating means to prompt said operator to match said control functional unit with a working functional unit; c) designation, by said operator, of said working functional unit by actuating said remote control means of said working functional unit; d) automatic addressing of said designated working functional unit; (e) transmission, by said designated working functional unit, of a message which includes an address of said working functional unit; and f) storage of said address in a non-volatile memory of said control functional unit.
Claim 2
Dependent Claim
152 words
A process for matching a plurality of functional units connected together via a bidirectional communication space, each of said plurality of functional units being provided with remote control means and indicating means, some of said plurality of functional units being provided with matching means, said process comprising: a) designation by an operator of a control functional unit by actuating matching means of said control functional unit; b) activation of said indicating means to prompt said operator to match said control functional unit with a working functional unit; c) designation, by said operator, of said working functional unit by actuating said remote control means of said working functional unit; d) automatic addressing of said designated working functional unit; (e) transmission, by said designated working functional unit, of a message which includes an address of said working functional unit; and f) storage of said address in a non-volatile memory of said control functional unit.
Claim 3
Dependent Claim
26 words
The process according to claim 1, wherein said address stored in step f) is allocated to said working functional unit in said automatic addressing step d).
Claim 4
Dependent Claim
34 words
The process according to claim 1, wherein said address stored in step f) is a subset address stored by said working functional unit after having received a message originating from said control functional unit.
Claim 5
Dependent Claim
111 words
The process according to claim 1, wherein said designation step c) further comprises the steps of: designation, by said operator, of a first control functional unit by actuating remote control means of said first control functional unit; transmission of a designation request message by said first control functional unit, said designation request message comprising at least one restrictive criterion; activation of said indication means, by other working functional units which satisfy said at least one restrictive criterion, to make their presence known to said operator; designation by said operator of a second working functional unit from among those which have made their presence known by said activation of said indication means.
Claim 6
Dependent Claim
131 words
The process according to claim 1, wherein before said automatic addressing step d), a test is conducted to see if a network address communicated by said control functional unit corresponds to said network address stored in a memory of said working functional unit and, if a result of said test is negative, then the network address communicated by said control functional unit is adopted for said working functional unit, and said automatic addressing of step d) proceeds, while if said network address communicated by said control functional unit is identical to said network address stored in said memory of said working functional unit, then said automatic addressing of step d) begins with a check on an availability of a unit address that has been previously stored by said working functional unit.
Claim 7
Dependent Claim
113 words
The process according to claim 1, wherein said operator chooses between giving a network address which is already allocated to said first control functional unit and to said working functional unit, to allow said first control functional unit to communicate with other functional units, or initiating an automatic addressing process to give said first control functional unit a new network address; communicating said network address of said first control functional unit to said second working functional unit, so that said second functional unit uses said same network address as said first control functional unit; automatic addressing of said working functional unit in order to give a unit address to said working functional unit.
Claim 8
Dependent Claim
147 words
The process according to claim 6, wherein the following steps allocate a network address which is already allocated to other functional units to said first control functional unit: initiation, by said first control functional unit, of a chaining proposal request via said bidirectional communication space; activation of said indication means by other functional units already possessing a network address to make their presence known to said operator; designation, by said operator, of at least one functional unit whose indication means are activated; sending, by said designated functional unit, of a message including a network address of said designated functional unit via said bidirectional communication space; reception of said message sent by said designated functional unit by said first control functional unit and adoption of said network address received in said message sent by said designated functional unit including said network address, by said first control functional unit.
Claim 9
Dependent Claim
22 words
The process according to claim 1, further comprising an automatic addressing step to allocate a unit address to said control functional unit.
