ABSTRACT:
A method is provided for controlling a plurality of electrical installations (A1-A3, B1-B4) of one or more types connected to a common data path (52), each including means for decoding a signal transmitted over this common data path to it by a single controller (50), comprising the steps of: transmitting, from each controlled installation to the single controller (50), an identification data frame, containing an installation type identifier code (b.sub.8 -b.sub.23); receiving of the identification data frame by the controller (50); decoding of the identification data frame by the controller (50); controlling of the installation (A1-A3, B1-B4) by the single controller according to a set of instructions (56, 57, 58) held in an instruction memory (55) of the single controller (50) and corresponding to the type of installation identified by the installation type identification code (b.sub.8 -b.sub.23); and further comprising the steps of: organizing electrical installations of a same type into groups (A, B, C, D); transmitting a group identifier code (b.sub.24 -b.sub.27) within a frame of data in either direction between each installation and the single controller (50); decoding (53, 54) of the received group identifier code by the single controller (50); controlling of the installation by the single controller (50) according to a subset of instructions (56, 57, 58) corresponding to the group (A, B, C, D) of installations within the type of installation, stored within the instruction memory (55) of the single controller (50).
