Operating as an I\/O device, the coupler manages communication between the master controller and modular digital or analog peripheral terminals, converting the fieldbus signals into the internal, terminal-independent K-bus representation.\u003c\/p\u003e\n\n\u003cp\u003eThis coupler supports automatic transmission rate recognition of 10\/100 Mbit\/s, facilitating simple integration into existing network topologies. System configuration and parameterization are managed via the Beckhoff KS2000 configuration software, which can connect through the Ethernet port or the integrated serial interface. The unit features an integrated power supply designed to power both the coupler electronics and the connected K-bus terminals.\u003c\/p\u003e\n\n\u003cp\u003eDesigned for compact control cabinet mounting, the \u003cstrong\u003eBECKHOFF BK9000\u003c\/strong\u003e provides direct connection for up to 64 Bus Terminals, and can be extended further using K-bus extension terminals.
