Method and device for setting the addresses of subscribers connected to a bus

摘要

The subject of the invention is a method and device for setting the addresses of subscribers which are connected to a bus, and via the bus to a central processing unit. The subscribers (3, 4, 5) are connected in series in daisy-chain fashion, via a separate control line (9) from the central processing unit (2). By a signal with a defined binary value on the control line (9) at the input to a subscriber (3, 4, 5), the subscriber accepts an address which is assigned to it from a transmission telegram, which is generated in the central processing unit, on the bus, and outputs the defined binary value to the control line. If the signal with the defined binary value at the input of a subscriber (3, 4, 5) fails, the daisy-chain connection is broken. If the daisy-chain connection exists, each subscriber outputs the received address to the bus (1), as the response to the poll of the central processing unit. <IMAGE>
