BK8000, BK8100 | RS485/RS232 Bus Couplers

The Bus Couplers BK8000 and BK8100 use the physics of the RS485 or RS232C (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 or RS232 interface can be used by any automation device (e.g. a PC with RS232 interface) to gain access to the Bus Coupler. Data exchange is made via an open, documented protocol. An ActiveX control and a DLL (KS8000) are available for Windows NT/2000/XP applications. The ActiveX control handles the necessary protocol for the exchange of data with the Bus Couplers, permitting the application to be implemented quickly. KS8000 LV also makes an interface available for the graphical programming system LabVIEW from National Instruments. The data is transmitted in a fixed format binary string secured by a checksum.

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).

The BK8100 Bus Coupler has an RS232C interface, and has been designed particularly for peer-to-peer connection.

Complex signal processing for analog I/Os, position measurement, …

The BK8000 and BK8100 Bus Couplers support the operation of all Bus Terminal types.

The analog and multi-functional Bus Terminals can be adapted to each specific application using the KS2000 configuration set. Depending on the type, the analog Bus Terminals' registers contain temperature ranges, gain values and linearisation characteristics. With the KS2000, the required parameters can be set on a PC. The Bus Terminals store settings permanently and in a fail-safe manner.

Optionally, the Bus Terminals can also be controlled by the control system. Via function blocks (FBs), the programmable logic controller (PLC) or the Industrial PC (IPC) handles configuration of the complete periphery during the start-up phase. If required, the controller can upload the decentrally created configuration data in order to centrally manage and store this data. Therefore, new adjustments are not necessary in the event of replacement of a Bus Terminal.
