ABB AX670 3BSE000566R1
Product Introduction
The ABB AX670 3BSE000566R1 is a high-performance PROFIBUS DP master interface module designed for ABB’s S800 I/O system within the 800xA and Advant OCS control platforms. This industrial-grade communication module enables seamless integration of PROFIBUS DP slave devices – such as variable frequency drives, I/O blocks, and sensors – into ABB’s distributed control architecture. The AX670 acts as a protocol gateway, translating PROFIBUS DP-V1 telegrams into the native S800 bus protocol for real-time data exchange with AC 800M controllers.
Engineered for mission-critical automation, the 3BSE000566R1 supports dual-channel redundancy with automatic bus termination, ensuring continuous operation even during network disturbances. Its integrated diagnostic suite monitors slave device health, cable integrity, and signal quality, providing actionable insights through Control Builder M engineering tools. For brownfield modernization projects, the AX670 bridges legacy PROFIBUS equipment with ABB’s latest control technology, eliminating costly system replacements.
Core Advantages and Technical Highlights
Network Resilience:
Dual isolated PROFIBUS ports enable redundant trunk-line configurations, with automatic switchover <10 ms during segment failure. The AX670 implements advanced error confinement to prevent faulty slaves from disrupting entire networks.
Deterministic Performance:
Achieves cycle times down to 1 ms for 32 slaves with 244 bytes I/O, synchronized via AC 800M‘s global clock. Hardware-based PROFIBUS ASIC ensures jitter-free communication critical for motion control applications.
Engineering Efficiency:
Auto-scan technology detects slave configurations automatically, reducing commissioning time by 70%. Integrated GSD library supports >5,000 third-party devices. TM I/O Safe allows module replacement under full voltage without system shutdown.
Typical Application Scenarios
The ABB AX670 3BSE000566R1 excels in automotive manufacturing, where it synchronizes robotic cells (KUKA, FANUC) with ABB’s DCS for paint shop conveyor control. In cement plants, it interfaces with weigh feeders and motor starters across 500m+ PROFIBUS segments, surviving high EMI environments.
Water utilities deploy the AX670 to integrate pump station VFDs (Siemens, Danfoss) into centralized SCADA, while pharmaceutical facilities use it for GMP-compliant batch process control with remote I/O islands. Mining operations leverage its vibration tolerance (-25°C startup) for crushing plant motor control.

Installation, Commissioning and Maintenance Instructions
Installation Preparation:
Verify PROFIBUS segment length ≤100m (12Mbps) or ≤1200m (93.75kbps). Use purple-shielded cables (Type A) with 90° connectors. Ground shield at both ends in high-noise environments. Ensure rack backplane voltage 5V±5%.
Maintenance Suggestions:
Quarterly inspect connector seals for IP20 integrity. Monitor “BUS FAULT” LED via Control Builder M. Replace modules showing persistent segment errors. Always use ABB’s FDT/DTM framework for slave device diagnostics. Store spares in original ESD packaging.
