ABSTRACT:
A circuit arrangement, for serial data transmission via at least one bus, is made up of plural subscriber stations each having a time circuit, by means of which faulty seizure of the bus can be discontinued. In order to achieve the highest possible level of availability with a comparatively large number of subscriber stations, the bus is connected to a data transmission network via a coupling device which itself includes a time circuit for the discontinuation of faulty seizures of the data transmission network by the bus. The circuit arrangement can be used advantageously in monitoring devices of electrical information transmission technology in which a plurality of stations each containing a plurality of locating devices are connected to a control processor.
