Title (EN) DATA TRANSMISSION ARRANGEMENT
(FR) DISPOSITIF DE TRANSMISSION DE DONNEES
Abstract: front page image
(EN)A data transmission arrangement for bi-directional transmission of bit-sequences between a central unit (CCU) and a plurality of terminal units (TU1, TU2, ...) is provided which is particularly adapted for data acquisition and feedback signaling of messages, and for process control. In the arrangement the data transmission can occur simultaneously with the power supply of the terminal units over a two-lead cable (L), to which a large number of terminal units can be connected in parallel. The method of operation of the arrangement permits an advantageously simple construction of the transmission and reception equipment in the central unit and the terminal units.
(FR)Un dispositif de transmission de donnees pour la transmission bidirectionnelle de sequences bit entre une unite centrale (CCU) et une pluralite de terminaux (TU1, TU2, ...) est particulierement adapte a l"acquisition et la reinjection de donnees de messages, et a la commande de traitement. Dans le dispositif, la transmission des donnees peut avoir lieu simultanement avec l"alimentation en puissance des terminaux par un cable a deux fils (L), sur lequel un grand nombre de terminaux peuvent etre connectes en parallele. La methode de fonctionnement du dispositif permet une construction simple et avantageuse du materiel de transmission et de reception de l"unite centrale et des terminaux.
