Profibus - Coupler
Product Description
The BK3000, BK3010, BK3100 and BK3110 bus couplers connect the PROFIBUS system as a DP/FMS slave to the electronic terminal blocks, which can be extended in modular fashion. One unit consists of the bus coupler, any number of up to 64 terminals and one end terminal. The BK3010 and BK3110 economy variants permit particularly economical creation of peripheral interfacing connections. Up to 64 digital input/output terminals can be connected.
The bus coupler recognises the connected terminals and automatically generates the affiliations of the inputs/outputs to the bytes of the process image. The first input/output signal is inserted in the first bit of one byte (LSB), beginning from the left. The bus coupler inserts further signals in this byte. Inputs and output are clearly separated. The bus coupler automatically begins a further byte if the number of inputs or outputs exceeds 8 bits.
Profibus is an open field
bus system with European Standards. The Profibus has a bus structure, and
up to 126 stations can be operated in a system. Baud rates of up to 12
MBaud are selectable, so that the transmission speed can be adjusted to
the demands of the technical process.

Complex signal processing for analog I/Os, position measurement
The BK3000 and BK3100 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. The controller automatically sets the required setting on power up.
The TRS GSD and type data files to the bus couplers support the bus terminal options. The GSD and Type data files can be loaded in the corresponding master configuration software to facilitate planning and design. Various configurations and parameters for the bus coupler can be selected via GSD and Type data files.
