Circuit arrangement for the transmission of data signals between control devices connected to one another via a loop system

Abstract From the Canadian patent

A system for transmitting data signals between control devices connected to each other by a transmission loop operated directionally dependent has a number of such control devices connected to the loop, with each control device including a signal compiler which compiles data signals to be transmitted in the form of a data signal block which includes at least one receiver address identifying another control device which is intended to receive the transmitted signal block. The signal compiler is followed by a transmit buffer which includes an intermediate storage. A prepared data signal block is accepted in the intermediate storage. A buffer control is connected to the intermediate storage. A …
