Beckhoff BK5200 DeviceNet Bus Coupler User Manual

1. Introduktion og overview

The Beckhoff BK5200 DeviceNet Bus Coupler is designed to connect the DeviceNet bus system to electronic terminal blocks, allowing for modular expansion of industrial control systems. This unit serves as a crucial interface for data exchange within a DeviceNet network.

The BK5200, along with its variants BK5210 and BK5220, forms a complete unit comprising the Bus Coupler, up to 64 standard terminals, and an end terminal. The BK5210 "Economy" variant offers a cost-effective solution for peripheral interfacing, supporting up to 64 digital input/output terminals.

For more extensive applications, the BK5220 "Economy plus" utilizes K-bus extension technology, enabling the connection of up to 255 spatially distributed Bus Terminals to a single Bus Coupler. This variant supports all Beckhoff system Bus Terminals and can manage up to 1,020 digital signals and a maximum of 256 analog input and output channels per slave in its full configuration.

Operating on the CAN protocol, the BK52x0 Bus Coupler adheres to the DeviceNet standard, facilitating the integration of various DeviceNet devices into a unified network. DeviceNet's communication object definition is specifically tailored for sensor/actuator data exchange in automation technology.

Configuration and parameterization of the Bus Couplers and Bus Terminals can be performed using the KS2000 configuration set on a PC. Commissioning is also possible without the KS2000, with corresponding EDS data files available for DeviceNet configuration tools.

3.4 Softwarekonfiguration

For advanced parameterization, use the Beckhoff KS2000 configuration software. Alternatively, standard DeviceNet configuration tools can be used with the provided EDS (Electronic Data Sheet) files. Ensure the correct EDS file for the BK5200 is loaded into your configuration software.

4. Betjeningsvejledning

Once installed and configured, the BK5200 operates as a transparent gateway between the DeviceNet network and the connected I/O terminals. Data exchange occurs automatically based on the DeviceNet communication protocol.

4.1 LED-statusindikatorer

Monitor the LED indicators on the top of the unit to ascertain the operational status of the Bus Coupler and the DeviceNet network:

• I/O ERR: Indicates an error with the connected I/O terminals.
• I/O RUN: Indicates normal operation of the I/O terminals.
• FORBINDE: Indicates a successful connection to the DeviceNet network.
• NS (Network Status): Indicates the status of the DeviceNet network.
• BUS OFF: Indicates the DeviceNet bus is off or in an error state.
• MS (Module Status): Indicates the status of the Bus Coupler module itself.
• LØB: Indicates the Bus Coupler is in run mode.
• SAMLET: General status indicator.

Refer to the DeviceNet specification and Beckhoff documentation for detailed interpretations of LED states.

5. Vedligeholdelse

The Beckhoff BK5200 Bus Coupler is designed for robust industrial environments and requires minimal maintenance. However, periodic checks can help ensure long-term reliability:

• Rensning: Keep the unit free from dust and debris. Use a soft, dry cloth for cleaning. Avoid using solvents or abrasive cleaners.
• Forbindelsesintegritet: Periodically inspect all wiring connections (power, DeviceNet, terminal blocks) to ensure they are secure and free from corrosion.
• Miljøforhold: Sørg for, at driftsmiljøet forbliver inden for de angivne temperatur- og fugtighedsområder for at forhindre for tidlig komponentsvigt.
• Firmwareopdateringer: Check the Beckhoff website periodically for any available firmware updates that may improve performance or address known issues. Follow official procedures for any updates.

6. Fejlfinding

If you encounter issues with your BK5200 Bus Coupler, consult the following troubleshooting guide:

6.1 Strømproblemer

• Ingen strøm: Verify the 24Vdc power supply is active and correctly connected to the terminals. Check for blown fuses in the power circuit.

6.2 DeviceNet Communication Issues

• NS/BUS OFF LED: If the Network Status (NS) or Bus Off LED indicates an error, check the DeviceNet cabling for breaks or shorts. Verify proper termination resistors are in place at both ends of the bus.
• CONNECT LED Off: Ensure the MAC ID and baud rate settings on the DIP switches match the DeviceNet network configuration. Check for duplicate MAC IDs on the network.
• No Data Exchange: Confirm that the EDS file used for configuration matches the BK5200. Verify the DeviceNet master is correctly configured to communicate with the BK5200's MAC ID.

6.3 I/O Terminal Issues

• I/O ERR LED: This indicates an issue with one or more connected I/O terminals. Check the individual terminal blocks for power, wiring errors, or module faults.
• Incorrect I/O Readings: Verify the I/O terminal configuration in your software matches the physical modules connected. Check wiring to sensors/actuators.

For persistent issues, consult the detailed Beckhoff documentation or contact technical support.
