ABB CM572-DP
Product Introduction
The ABB CM572-DP is a dedicated PROFIBUS DP slave interface module for ABB’s AC500 PLC platform, enabling seamless integration into industrial automation networks dominated by Siemens, Rockwell, and other PROFIBUS master systems. Designed as a plug-in module for PM5xx CPU racks, the CM572-DP converts AC500 controllers into intelligent field devices capable of exchanging 244 bytes of I/O data per cycle with DP masters.
As part of ABB’s scalable communication portfolio, this module supports PROFIdrive and PROFISafe protocols, allowing AC500-based motor starters, valve terminals, and safety systems to operate as native nodes in multi-vendor production lines. The ABB CM572-DP features automatic baud rate detection and GSD file (GSDML-V2.3) compatibility, eliminating complex configuration steps while maintaining deterministic response times ≤1 ms for critical motion control applications.
Core Advantages and Technical Highlights
Plug-and-Play Integration: Automatic detection by DP masters (e.g., Siemens S7-400) using standardized GSD files. Hot-plug capability allows module replacement without network shutdown.
Dual-Port Architecture: Integrated repeater functionality enables daisy-chaining to subsequent nodes without external couplers, reducing cabinet space in packaging machinery control cabinets.
Diagnostic Depth: Real-time monitoring of bus voltage (5V±10%), telegram error rates, and station status. Detailed diagnostics accessible via ABB Automation Builder or PROFIBUS master engineering tools.
Robust Signal Integrity: Advanced line drivers with short-circuit protection (IEC 61158-2) maintain communication during ground faults. 1500V isolation prevents ground loops in electrified rail systems.
Extended Environment Tolerance: Operates at full 12Mbps speed from -25°C to +70°C without derating. Conformal coating resists corrosive atmospheres in chemical processing.
Typical Application Scenarios
Automotive Body Shops: Connects AC500-controlled welding robots to Siemens PLC-based transfer lines. The CM572-DP‘s ≤1ms cycle time synchronizes spot welding guns with conveyor positioning.
Water Treatment Plants: Interfaces ABB PLC-controlled chemical dosing stations with legacy PROFIBUS DCS. Module diagnostics alert operators to cable degradation before communication loss.
Cement Plant Baghouse Systems: Links dust collector pulse valves (ABB PM564 control) to central SCADA. PROFIBUS Safe functionality enables emergency stop cascades across 500m distances.
