Product Description:
The BX9000-0000 is a compact controller produced by Beckhoff and is part of the BX Bus Terminal Controllers series. The unit combines a small PLC with fieldbus and I/O interfaces so that distributed terminal blocks can be driven directly from the head station without a separate processor. In industrial automation, the device is mounted at the end of a K-bus segment to execute user logic, collect process data from attached terminals, and forward information over Ethernet to higher-level control systems.
On the local side, the controller manages up to 2040 I/O digital channels and a further 1024 I/O analog points, which set the maximum number of process signals assignable to the attached terminal stack. The 16-bit microcontroller cycles this data from program memory of 256 kbyte, ensuring deterministic execution of IEC routines. Communication to the plant network is handled by an Ethernet interface that auto-negotiates 10/100 Mbaud and supports cable runs of 100 m, permitting cabinet-to-switch distances typical of factory layouts. The K-bus backplane can source 1450 mA, so power-hungry terminals such as relays or analog output blocks remain within the available current budget. An FSTN display with two lines of sixteen characters provides status and basic parameter access, and a dielectric strength of 500 V isolates field wiring from logic.
Expansion and power limits determine the scale of the installation. Up to 64 K-bus terminals can be inserted, and eight SSB slaves can be scanned through the serial sub-bus, allowing mixed signal stacks and intelligent modules to be connected on the same station. Input images are transferred to the CPU in 2048-byte blocks to match the controller's network message length. Power contacts route up to 10 A for actuator loads, while logic and I/O share a single 24 VDC feed, and the enclosure has an IP20 protection rating suitable for control cabinets.
