2.1 The Beckhoff Bus Terminal system
Up to 256 Bus Terminals, with 1 to 16I/O channels per signal form
The Bus Terminal system is the universal interface between a fieldbus system and the sensor / actuator
level. A unit consists of a Bus Coupler as the head station, and up to 64 electronic series terminals, the last
one being an end terminal. Up to 255 Bus Terminals can be connected via the K-bus extension. For each
technical signal form, terminals are available with one, two, four or eight I/O channels, which can be mixed
as required. All the terminal types have the same mechanical construction, so that difficulties of planning and
design are minimized. The height and depth match the dimensions of compact terminal boxes.
Decentralised wiring of each I/O level
Fieldbus technology allows more compact forms of controller to be used. The I/O level does not have to be
brought to the controller. The sensors and actuators can be wired decentrally, using minimum cable lengths.
The controller can be installed at any location within the plant.
Industrial PCs as controllers
The use of an Industrial PC as the controller means that the operating and observing element can be
implemented in the controller's hardware. The controller can therefore be located at an operating panel, in a
control room, or at some similar place. The Bus Terminals form the decentralised input/output level of the
controller in the control cabinet and the subsidiary terminal boxes. The power sector of the plant is also
controlled over the bus system in addition to the sensor/actuator level. The Bus Terminal replaces the
conventional series terminal as the wiring level in the control cabinet. The control cabinet can have smaller
dimensions.
Bus Couplers for all usual bus systems
The Beckhoff Bus Terminal system unites the advantages of a bus system with the possibilities of the
compact series terminal. Bus Terminals can be driven within all the usual bus systems, thus reducing the
controller parts count. The Bus Terminals then behave like conventional connections for that bus system. All
the performance features of the particular bus system are supported.
Mounting on standardized mounting rails
The installation is standardized thanks to the simple and space-saving mounting on a standardized mounting
rail (EN60715, 35mm) and the direct wiring of actuators and sensors, without cross connections between
the terminals. The consistent labelling scheme also contributes.
The small physical size and the great flexibility of the Bus Terminal system allow it to be used wherever a
series terminal is also used. Every type of connection, such as analog, digital, serial or the direct connection
of sensors can be implemented.
Modularity
The modular assembly of the terminal strip with Bus Terminals of various functions limits the number of
unused channels to a maximum of one per function. The presence of two channels in one terminal is the
optimum compromise of unused channels and the cost of each channel. The possibility of electrical isolation
through potential feed terminals also helps to keep the number of unused channels low.
Display of the channel state
The integrated LEDs show the state of the channel at a location close to the sensors and actuators.

K-bus
The K-bus is the data path within a terminal strip. The K-bus is led through from the Bus Coupler through all
the terminals via six contacts on the terminals' side walls. The end terminal terminates the K-bus. The user
does not have to learn anything about the function of the K-bus or about the internal workings of the
terminals and the Bus Coupler. Many software tools that can be supplied make project planning,
configuration and operation easy.
Potential feed terminals for isolated groups
The operating voltage is passed on to following terminals via three power contacts. You can divide the
terminal strip into arbitrary isolated groups by means of potential feed terminals. The potential feed terminals
play no part in the control of the terminals, and can be inserted at any locations within the terminal strip.
Up to 64Bus Terminals can be used in a terminal block, with optional K-bus extension for up to 256Bus
Terminals. This count does include potential feed terminals, but not the end terminal.
Bus Couplers for various fieldbus systems
Various Bus Couplers can be used to couple the electronic terminal strip quickly and easily to different
fieldbus systems. It is also possible to convert to another fieldbus system at a later time. The Bus Coupler
performs all the monitoring and control tasks that are necessary for operation of the connected Bus
Terminals. The operation and configuration of the Bus Terminals is carried out exclusively by the Bus
Coupler. Nevertheless, the parameters that have been set are stored in each Bus Terminal, and are retained
in the event of voltage drop-out. Fieldbus, K-bus and I/O level are electrically isolated.
If the exchange of data over the fieldbus is prone to errors or fails for a period of time, register contents (such
as counter states) are retained, digital outputs are cleared, and analog outputs take a value that can be
configured for each output when commissioning. The default setting for analog outputs is 0 V or 0 mA. Digital
outputs return in the inactive state. The timeout periods for the Bus Couplers correspond to the usual
settings for the fieldbus system. When converting to a different bus system it is necessary to bear in mind the
need to change the timeout periods if the bus cycle time is longer.
The interfaces
A Bus Coupler has six different methods of connection. These interfaces are designed as plug connectors
and as spring-loaded terminals.

2.2 BK7150 - Introduction
Fig.1: BK7150
Bus Coupler with CC-Link Slave Interface
The “Compact” Bus Couplers BK7150 connects the CC-Link system 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 K-bus extension technology allows for the connection to one Bus Coupler of up to
255 Bus Terminal spatially distributed.
The Bus Coupler recognizes 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 outputs
are clearly separated. The Bus Coupler automatically begins a further byte if the number of controller inputs
or outputs exceeds 8 bits.
CC-Link is an open fieldbus system. Baud rates up to 10 Mbaud can be selected via a switch, so that the
transfer speed can be adapted to the requirement of the technical process.
Complex signal processing for analog I /Os, position measurement, …
The BK7150 Bus Coupler supports 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 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 linearization 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.
