CAN CAL / CANopen - Coupler

Product Description

The BK5000 and BK51x0 bus couplers connect the CAN bus system to the electronic terminal blocks, which can be extended in modular fashion. One unit consists of one bus coupler, any number of up to 64 terminals and one end terminal. The BK5110 economy variant permits particularly economical creation of peripheral interfacing connections. Up to 64 digital input/output terminals can be connected.

The bus coupler works on the CAN protocol basis as defined in ISO 11898. In the bus coupler BK5000 the network services are implemented according to CAL; it can be operated in any CAL networks. The BK51x0 are CANopen devices. As well as network services, CANopen also determines the data allocation for automation systems applications, and has established itself as an open CAN application layer. The BK51x0 support all types of CANopen communications and can also be used without difficulty in manufacturer-specific CAN environments due to the simple structure of this protocol definition.

Complex signal processing for analog I/Os, position measurement

The BK5000 and BK5120 bus couplers support the operation of all bus terminals. As far as the user is concerned, handling of the analog inputs/outputs is no different to other series. The information is available in the process image of the controller for processing in the form of an byte-array.

The analog and multifunctional 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. Using the KS2000 software, the required parameters can be set on a PC. The bus terminal stores 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 Personal Computer (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.

Parameterising can also be carried out using any CANopen configuration tools. For this, eds data files are available, which describe all the setting options for the CANopen coupler. For most applications, however, no configuration is necessary, as CANopen provides practical default values for all parameters.
