BECKHOFF BX8000 BX Series RS232/RS485 Bus Terminal Controller

Description

Integrating decentralized execution with flexible communication capabilities, the BECKHOFF BX8000 functions as a high-performance programmable logical controller designed for the Beckhoff Bus Terminal system. This compact controller bridges standard serial communication interfaces (RS232 and RS485) with industrial I/O signals, enabling modular control topologies in complex plant installations. Engineered with 256 kbytes of program memory and 256 kbytes of data memory, it provides robust capabilities for execution tasks configured via the TwinCAT software suite in compliance with the IEC 61131-3 standard.

The unit features a built-in illuminated FSTN character display alongside an integrated navigation joystick, allowing operators to execute diagnostic functions, configure network parameters, and read localized status messages directly at the device. Connectivity is further enhanced by an integrated CANopen-based Smart System Bus (SSB) designed to link additional peripheral modules or subsidiary controller units.

Features

• Dual integrated serial interfaces: COM1 configured as dedicated RS232; COM2 configurable as RS232 or RS485.
• Direct connection for up to 64 local Bus Terminals, expandable to a maximum of 255 modules utilizing K-bus extension technology.
• Illuminated FSTN display showing 2 lines of 16 characters for customized status tracking and system diagnostics.
• IEC 61131-3 compatible programming support with capability for online program alterations.
• Battery-backed integrated real-time clock for system time-stamping and scheduling tasks.
• Integrated power contacts rating of up to 24 V DC at 10 A max.

Applications

• Distributed machinery control and local pre-processing.
• Serial-to-fieldbus gateway execution in infrastructure monitoring.
• HVAC and building automation networks using Modbus RTU protocols.
• Remote telemetry and processing stations requiring local status displays.

Technical Specifications

Connections and Interfaces

Installation Guidelines

• Mounting: Mount horizontally on standard 35 mm DIN rail (conforming to EN 60715) using the integrated locking mechanism.
• Wiring: Connection terminals utilize tool-actuated spring clamps. Solid conductors (0.08 to 2.5 mm squared) and flexible conductors with wire-end ferrules (0.14 to 1.5 mm squared) should be stripped to a length of 8 to 9 mm prior to insertion.
• Shielding & Grounding: Ensure a low-impedance connection to the functional earth terminal to safeguard against serial interface EMC disturbances.

Compliance and Certifications
