Abstract:

PCT No. PCT/FR85/00008 Sec. 371 Date Nov. 15, 1985 Sec. 102(e) Date Nov. 15, 1985 PCT Filed Jan. 17, 1985 PCT Pub. No. WO85/03395 PCT Pub. Date Aug. 1, 1985.A network of at least two modules M1, M2 which are addressable and connected by a standard transmission line, for example an electric power distribution network RDE. The modules are connected either to sensors CAPT or actuators ACTI, or to a processor TERMI. An order number is assigned to the modules. The transmissions from the modules are sequenced by measuring the time elapsed between the messages. The messages are active signals having a predetermined duration, and all signals of shorter duration are suppressed. The impedance of the modules is low during emission and otherwise. Applications to the fields of personal computers and of domestic electric power distribution.
