Description

Integrating industrial I/O signals directly into Ethernet networks, the BECKHOFF BK9100 functions as a high-performance Ethernet TCP/IP bus coupler designed for modular Bus Terminal configurations. This interface module bridges the fieldbus-independent K-bus system with standard Ethernet networks, permitting efficient decentralized automation architectures.

The unit features an integrated 3-port switch (configured as a 2-channel switch and one internal port), facilitating line topology and star topology physical wiring without requiring external network switches. Communication capabilities include multi-protocol support, enabling seamless integration within TwinCAT ADS systems, Modbus TCP networks, and Beckhoff real-time Ethernet environments. Configuration and diagnostics are conveniently handled via the KS2000 software interface.

Features

Dual-Channel Switch: Equipped with 2 x RJ45 ports for cost-efficient line topology cascading of up to 20 BK9100 units.
Flexible Expansion: Connects up to 64 Bus Terminals directly, with scalability up to 255 terminals using a K-bus extension.
Multi-Protocol Support: Compatible with TwinCAT ADS, Modbus TCP, and Beckhoff Real-Time Ethernet protocols.
Auto-Negotiation: Detects transmission speeds of 10 or 100 Mbit/s automatically.
Reliable Isolation: Features 500 V electrical isolation between power contacts, supply voltage, and the fieldbus network.

Applications

Process control and industrial automation networks
Decentralized data acquisition systems
Factory floor I/O expansion in line and star topologies
Water and wastewater management systems
Material handling and building automation infrastructure

Key Features:

#Beckhoff Bus Terminals #Ethernet Bus Couplers

How many Bus Terminals can be connected to the Beckhoff BK9100?

The BK9100 can connect up to 64 Bus Terminals directly. With a K-bus extension, the network can be expanded to support up to 255 Bus Terminals.

Which communication protocols does the BK9100 support?

The BK9100 supports TwinCAT ADS, Modbus TCP, and Beckhoff real-time Ethernet protocols.

Does the BK9100 support daisy-chain topology?

Yes, because it includes an integrated 2-channel switch (2 x RJ45 ports), you can cascade up to 20 BK9100 units in a line topology without requiring external switches.

What is the maximum current supply capacity for the internal K-bus?

The BK9100 delivers a maximum current supply of 1750 mA to the internal K-bus system.

What cables are recommended for connection to the BK9100?

A Category 3 (10 Mbit/s) or Category 5 (100 Mbit/s) 4 x 2 twisted-pair copper cable is recommended for reliable data transfer.
