BK8000 | RS485 Bus Coupler
Thông tin về Beckhoff BK8000:
The BK8000 Bus Coupler usess the physics of the RS485 (V.24) specification for data transmission. Application of the Bus Coupler with a serial interface is suited to those cases in which the use of a fieldbus system can be omitted. The RS485 interface can be used by any automation device with the corresponding interface to gain access to the Bus Coupler. Data exchange is made via an open, documented protocol.
Another mode of operation is for the Bus Coupler to function in master/slave mode as a fieldbus multiplexer. The input data from one device are copied directly to the outputs of the other, without the aid of an additional master – and vice versa.
The BK8000 Bus Coupler communicates via an RS485 interface. This permits a bus to be constructed with up to 99 participating devices (addresses can be set with an address selector).
