Product Details

8-AXIS BXI4/2-01-B Product Description

The Berkeley BXI4-2-01-B is an 8-axis motion controller card engineered for the BXI4 series platform, delivering deterministic real-time control across multi-axis servo and drive networks. Designed for demanding smart factory environments, this controller card serves as the central data link between field-level servo drives, PLC controllers, remote I/O modules, HMI panels, SCADA systems, and upper-level MES platforms. With native EtherCAT and CANopen protocol support, the BXI4-2-01-B eliminates communication bottlenecks and enables seamless, high-speed data exchange across the entire automation architecture.

In modern smart manufacturing, the ability to synchronise motion data across eight axes simultaneously — while maintaining sub-millisecond cycle times — is critical to achieving production precision and system transparency. The BXI4-2-01-B addresses this requirement by integrating directly into the BXI4 series control platform, providing a unified communication backbone that connects servo amplifiers, encoder feedback modules, distributed I/O racks, and industrial Ethernet switches within a single, coherent network topology.

The BXI4-2-01-B operates at the heart of a layered smart factory data architecture. At the field level, servo drives and encoder feedback units — such as those in the Berkeley BXI4 servo amplifier series — transmit real-time position, velocity, and torque data to the controller card via the EtherCAT bus. This high-speed cyclic data exchange ensures that all eight axes remain synchronised with microsecond-level precision, which is essential for coordinated multi-axis CNC machining, robotic assembly, and precision dispensing applications.

Moving up the network hierarchy, the BXI4-2-01-B interfaces with distributed remote I/O modules over CANopen, collecting digital and analogue signals from proximity sensors, pressure transducers, and vision system triggers distributed across the production floor. These signals are aggregated and forwarded to the PLC controller layer — compatible with mainstream platforms including Siemens S7-series and Mitsubishi MELSEC controllers — where logic execution and interlock management take place.

At the supervisory level, the controller card's network data is made available to HMI panels and SCADA platforms such as Wonderware InTouch, Ignition SCADA, and WinCC, enabling operators to monitor axis positions, cycle counts, alarm states, and drive health in real time. The BXI4-2-01-B supports OPC-UA data publishing, allowing SCADA historians to log motion events and production metrics for trend analysis and predictive maintenance workflows.

For edge-level data processing, the BXI4-2-01-B can be paired with an industrial edge gateway — such as those supporting MQTT or OPC-UA northbound communication — to push aggregated motion and I/O data to cloud-based MES or ERP platforms. This enables plant managers to access real-time KPIs, OEE dashboards, and alarm histories from any location, supporting remote diagnostics and production transparency without requiring on-site access.

The system architecture is further strengthened by integrating managed industrial Ethernet switches with PROFINET or EtherCAT-compatible ports, ensuring deterministic packet delivery across the factory network. Power integrity for the controller card and connected field devices is maintained through DIN-rail industrial power supplies with redundant output capability, preventing motion faults caused by voltage transients during high-load servo acceleration cycles.

For applications requiring protocol bridging — for example, connecting legacy PROFIBUS DP field devices or Modbus RTU sensors into the EtherCAT network — a dedicated protocol gateway module can be deployed alongside the BXI4-2-01-B, transparently converting data frames without introducing latency into the real-time control loop. This makes the BXI4-2-01-B a future-proof investment for factories undergoing phased digital transformation, where legacy and modern devices must coexist on the same network backbone.

Protocol Fragmentation: Many automation sites operate a mix of EtherCAT servo drives, CANopen I/O modules, and legacy Modbus or PROFIBUS devices. The BXI4-2-01-B's dual-protocol architecture — combined with an optional gateway module — consolidates these disparate communication layers into a single, unified data stream, eliminating the protocol silos that cause data gaps and manual reconciliation overhead.

Data Islands and Production Blind Spots: Without a centralised motion controller with network reporting capability, axis-level data — such as following error, drive temperature, and encoder fault codes — remains trapped at the device level. The BXI4-2-01-B surfaces this data to SCADA and HMI layers in real time, giving process engineers full visibility into every axis's operational state and enabling proactive intervention before faults escalate into unplanned downtime.

Remote Monitoring and Diagnostics: For multi-site manufacturers or OEM machine builders, the ability to remotely diagnose motion faults without dispatching a field engineer is a significant operational advantage. The BXI4-2-01-B supports remote parameter reading and alarm log retrieval via the network interface, allowing support teams to identify root causes — such as encoder signal degradation, drive overcurrent, or communication timeout — and issue corrective instructions remotely.

Production Line Transparency and Alarm Traceability: The controller card's event logging capability records timestamped alarm events, axis state transitions, and communication errors, providing a complete audit trail for quality management and root-cause analysis. This data can be exported to SCADA historians or MES databases, supporting ISO-compliant production reporting and continuous improvement initiatives.

System Scalability: As production requirements grow, the BXI4 platform supports axis expansion through additional controller cards and network nodes, allowing manufacturers to scale from 8-axis to multi-card configurations without redesigning the control architecture. The BXI4-2-01-B's standardised EtherCAT and CANopen interfaces ensure compatibility with a broad ecosystem of servo drives, I/O modules, and network devices from leading automation vendors.

Q1: What is the communication cycle time of the BXI4-2-01-B over EtherCAT?The BXI4-2-01-B supports EtherCAT cycle times as low as 250 µs for 8-axis synchronised motion, ensuring deterministic real-time control suitable for high-speed CNC, robotic, and precision assembly applications. Network latency is negligible within a properly configured EtherCAT ring or line topology.

Q2: Is the BXI4-2-01-B compatible with third-party SCADA and HMI systems?Yes. The BXI4-2-01-B supports OPC-UA data publishing and can interface with leading SCADA platforms including Ignition, WinCC, and Wonderware InTouch, as well as HMI panels from Siemens, Weintek, and Proface. CANopen and EtherCAT data can be mapped to standard process variables accessible by any OPC-UA-compliant supervisory system.

Q3: Can the BXI4-2-01-B bridge legacy PROFIBUS or Modbus devices into an EtherCAT network?Direct protocol bridging requires an external gateway module deployed alongside the BXI4-2-01-B. Once the gateway translates PROFIBUS DP or Modbus RTU data into EtherCAT-compatible frames, the controller card can process and distribute this data transparently within the BXI4 control platform, preserving real-time performance without modifying the existing field device wiring.

Q4: What does the 12-month warranty cover, and has the unit been tested before shipment?Every BXI4-2-01-B unit undergoes full functional testing prior to dispatch, including communication protocol verification, axis initialisation checks, and network interface validation. The 12-month warranty covers manufacturing defects and component failures under normal operating conditions, with technical support available via NANKMOS for fault diagnosis, RMA processing, and replacement coordination.
