BK5110, BK5120 | Контроллер ввода-вывода CANopen с возможностью подключения до 64 цифровых модулей

The 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.

With the K-bus extension technology, the “Economy plus” Bus Coupler BK5120 allows the connection of up to 255 spatially distributed Bus Terminals to one Bus Coupler. The Bus Coupler works on the CAN protocol basis as defined in ISO 11898. In addition to network services, CANopen also determines the data allocation for automation systems applications and has established itself as an open CAN application layer. The Bus Couplers 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. The firmware can be updated via the configuration interface.

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

The BK5120 Bus Coupler supports the operation of all Bus Terminals. As far as the user is concerned, handling of the analog inputs/outputs is not different to other series. The information is available in the process image of the controller for processing in the form of a byte array.

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.

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.
