Fig. 1: BK5200 – Bus Coupler for DeviceNet The BK5200 Bus Coupler connects the DeviceNet bus system to the modularly extendable electronic terminal blocks. One unit consists of one Bus Coupler, any number from 1 to 64 terminals and one bus end terminal.
Fig. 2: BK5250 – Compact Bus Coupler for DeviceNet The Compact Bus Coupler BK5250 for DeviceNet extends the Beckhoff Bus Terminal system by a cost- optimized version in a compact housing. Up to 64 Bus Terminals are supported; with the Terminal Bus Extension, up to 255 Bus Terminals can be connected.
Product overview LC5200 - Introduction Fig. 3: LC5200 - Low-cost Bus Coupler for DeviceNet The LC5200 low-cost bus coupler is characterized by its compact design and less expensive connection technology. It corresponds to the functions of the BK5210 DeviceNet Bus Coupler in relation to operation with Bus Terminals and its fieldbus properties.

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.

Basic Function Principles 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.
The BECKHOFF DeviceNet devices have a powerful implementation of the protocol. Through active participation in the ODVA's technical committees, BECKHOFF are contributing to the further development of this bus system, and has in this way itself gathered profound DeviceNet expertise.
Diagnostics The extensive diagnostic functions of the BECKHOFF DeviceNet devices allow rapid fault localisation. The diagnostic messages are transmitted over the bus and collated by the master. The status of the network connection, the device status, the status of the inputs and outputs and of the power supply are displayed by LEDs.
Basic Function Principles Analog outputs receive 16 bits of data, i.e. two bytes, per channel. An analog output terminal with 2 channels must therefore receive 4 bytes. A digital output terminal with 2 channels requires a total of 2 bits of data, 1 bit for each channel. First the data from all the analog outputs The first 4 bytes of an object transmitted to the terminal strip are assigned to the first analog output terminal, which is the analog output terminal closest to the Bus Coupler.
0. As soon as an error occurs, the I/O ERR LED lights up and the status byte contains the value 1. 3.3.3 Vendor ID The Vendor ID is # 108 3.3.4 DeviceNet Group The BK5200, BK5210 and LC5200 Bus Couplers are exclusively Group 2 devices.

Fig. 9: Spring contacts of the Beckhoff I/O components Dimensions The system of the Beckhoff Bus Terminals is characterized by low physical volume and high modularity. When planning a project it must be assumed that at least one Bus Coupler and a number of Bus Terminals will be used.
Mounting and wiring Fig. 10: Dimensions Installation on mounting rails WARNING Risk of injury through electric shock and damage to the device! Bring the Bus Terminals system into a safe, de-energized state before starting mounting, disassembly or wiring of the Bus Terminals. Mounting The Bus Couplers and Bus Terminals are attached to commercially available 35 mm mounting rails (DIN rail according to EN 60715) by applying slight pressure:...
Page 21
Mounting and wiring 1. Carefully pull the orange-colored lug approximately 1 cm out of the terminal to be disassembled, until it protrudes loosely. The lock with the mounting rail is now released for this terminal, and the terminal can be pulled from the mounting rail without excessive force. 2.
Mounting and wiring Power supply, potential groups Power supply The Bus Couplers require a 24 V DC supply for their operation. In the case of the BK52x0 Bus Couplers this is connected via the upper spring-loaded terminals marked "24 V" and "0 V". This supply voltage feeds not only the Bus Coupler electronics, but also the Bus Terminals via the K-bus.
Note: All the Bus Terminals are electrically isolated from the K-bus. The K-bus is thus electrically isolated from everything else. Fig. 11: BK5200, BK5210, BK5250 – potential groups The LC5200 does not provide electrical isolation from the fieldbus and peripheral level. If the peripheral level nevertheless needs to have an electrically isolated implementation, this can easily be achieved through the use of isolating terminals (KL9xxx).
Mounting and wiring Electrical isolation BK5200, BK5210 The BK5200 and BK5210 Bus Couplers have electrical isolation between the DeviceNet bus cable and the communication electronics of the Bus Coupler. Fig. 12: Potential levels of the BK5200 and BK5210 LC5200 The LC5200 does not provide electrical isolation from the fieldbus and peripheral level. If the peripheral level nevertheless needs to have an electrically isolated implementation, this can easily be achieved through the use of isolating terminals (KL9xxx).
Mounting and wiring DeviceNet connection – pin assignment A 5-pin connector is supplied for the connection of the DeviceNet bus cable. When it is plugged into the Bus Coupler, pin 1 is at the top. The figure shows the socket in the Bus Coupler. The power supplied by this plug is isolated from the power supply of the terminal to the right of the Bus Coupler.
Mounting and wiring Bus cable lengths and pin assignment The maximum length of cable which can be used depends on the selected baud rate. The following lengths should be understood as the total length of the main line plus any drop lines. Baud rate Bus length 500 kbit/s...

Parameterization and Commissioning Parameterization and Commissioning Start-up behaviour of the Bus Coupler Immediately after being switched on, the Bus Coupler checks, in the course of a self-test, all the functions of its components and the communication on the K-bus/E-bus. The red I/O LED blinks while this is happening. After completion of the self-test, the Bus Coupler starts to test the attached Bus Terminals (the "Bus Terminal Test"), and reads in the configuration.
Parameterization and Commissioning or input value is represented, according to the standard settings, by "7FFF" hex. Negative input/output values, e.g. -10 V are mapped as "1000" hex. The intermediate values are correspondingly proportional. A range with a resolution of 15 bits is not achieved for all input and output stages. With an actual resolution of 12 bits, the last 3 bits for outputs have no effect and for inputs they are read "0".

Parameterization and Commissioning instance, the consistency must be extended. The different bus systems guarantee consistency up to the required length. Correct transfer of the consistent data from the bus system master to the controller is important. The corresponding manual for the bus system will provide a detailed description of the correct procedure, in particular the description of the master interfaces used.
Set all the DIP switches to the desired configuration before you switch on the Bus Coupler. Switches 7 and 8 are used to set the baud rate, as shown in the following table. Fig. 22: BK5200 - Configuration Fig. 23: DIP switch...

Parameterization and Commissioning Switch on the Bus Coupler When you have set all the DIP switches to the desired configuration you can switch on the Bus Coupler. Any changes you make to the switches while the system is in operation will have no effect until the next time it is switched on.
Parameterization and Commissioning Diagnostic LEDs After switching on, the Bus Coupler immediately checks the connected configuration. Error-free start-up is indicated when the red "I/O ERR" LED goes out. If the "I/O ERR" LED blinks, an error in the area of the terminals is indicated.
