Abstract

Abstract An arrangement is disclosed for time division multiplex data transmission with a bus system which includes a bus line and a plurality of participators connected to the bus line in data transmitting connection with each other in a predetermined succession in a predetermined combination, in which each participator has at least one programmable counter having a counting input for connection with a synchronizing signal generator and an output for connection with a switching device to produce a data transmitting connection between the bus line and a data source or sink of this participator, whereby the counters of all participators are synchronized with each other. The arrangement includes apparatus to detect short circuits and to shut down individual sections of the bus line to protect the individual sections without shutting down all sections.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 112 words
An arrangement for time division multiplex data transmission through a bus system which includes a bus line and a plurality of terminals connected to the bus line in a predetermined succession and in a predetermined combination, in which each terminal establishes a data transmitting connection to the bus line and means connected in the bus system for detecting short circuits and shutting down individual sections of the bus line to protect the individual sections without shutting down all sections, including safety devices respectively connecting the terminals to the individual sections of the bus line, and an energy source connected to the bus line at point of common connection to said safety devices.
Claim 2
Dependent Claim 112 words
An arrangement for time division multiplex data transmission through a bus system which includes a bus line and a plurality of terminals connected to the bus line in a predetermined succession and in a predetermined combination, in which each terminal establishes a data transmitting connection to the bus line and means connected in the bus system for detecting short circuits and shutting down individual sections of the bus line to protect the individual sections without shutting down all sections, including safety devices respectively connecting the terminals to the individual sections of the bus line, and an energy source connected to the bus line at point of common connection to said safety devices.
Claim 3
Dependent Claim 34 words
An arrangement as claimed in claim 1 wherein the bus line includes a central terminal having at least one safety module directly connected therewith, and an energy source directly connected to the central terminal.
