ABB CM572-DP

Product Introduction

The CM572-DP is a specialized Profibus DP communication module from ABB, designed to integrate AC500 PLC systems into Profibus-based industrial networks. As a Profibus DP V1 slave module, it enables seamless data exchange between AC500 controllers and Profibus master devices (such as SCADA systems, HMI panels, or other PLCs), facilitating real-time transmission of process data and control signals in automation environments.

Engineered for the AC500 platform, CM572-DP leverages ABB’s modular design philosophy, allowing easy expansion of PLC communication capabilities without modifying core control architecture. Its support for data rates up to 12 Mbps ensures high-speed communication, critical for time-sensitive applications like conveyor synchronization or precision dosing systems. Whether deployed in automotive factories, food processing lines, or water treatment plants, CM572-DP acts as a reliable bridge between local PLC logic and wider industrial networks, enhancing system interoperability and flexibility.

Core Advantages and Technical Highlights

High-speed Profibus integration

CM572-DP supports Profibus DP V1 with data rates up to 12 Mbps, enabling rapid transmission of I/O data and parameter values. In a pharmaceutical packaging line, this speed ensures the AC500 PLC (via CM572-DP) receives real-time feedback from Profibus-enabled weigh scales, adjusting filling machine speeds within 10 ms to maintain dosage accuracy—critical for regulatory compliance.

Seamless AC500 compatibility

As a native AC500 module, CM572-DP integrates directly with the system backplane, eliminating the need for external wiring between the PLC CPU (e.g., PM554) and communication interface. This plug-and-play design reduces installation time by 30% compared to third-party adapters, while ensuring consistent data flow between the CPU and Profibus network.

Industrial-grade reliability

With 2.5 kV AC isolation and operation from 0°C to +60°C, CM572-DP thrives in electrically noisy environments. In a steel mill’s rolling line, where high-voltage motors generate electromagnetic interference, the module maintains stable communication with Profibus drives, preventing data loss that could cause production delays.

Typical Application Scenarios

In an automotive assembly line’s robotic cell:

CM572-DP modules connect AC500 PLCs to Profibus DP-enabled robotic controllers, enabling coordinated motion control of welding robots.

The module transmits real-time position data (from DI524 digital inputs monitoring encoders) to the Profibus master (a central SCADA system), ensuring robots operate within 0.5 mm tolerance.

Profibus DP V1 support allows acyclic data exchange, such as robot diagnostic logs, which are sent to maintenance systems for predictive fault detection.

During line reconfigurations, CM572-DP’s auto-negotiation feature adapts to new data rates (e.g., switching from 1.5 Mbps to 12 Mbps) without manual reconfiguration, minimizing downtime.

In a beverage bottling plant’s conveyor system:

CM572-DP facilitates communication between the AC500 PLC and Profibus-based variable speed drives (e.g., ABB ACS880), regulating conveyor speed based on bottle detection signals.

The module’s status LED provides instant visual confirmation of communication health, allowing technicians to quickly identify issues (e.g., a loose Profibus cable) during troubleshooting.

Integration with DO524 digital outputs enables the PLC to trigger conveyor stops via Profibus commands, preventing bottle jams when sensors detect misalignment.

Installation, Commissioning and Maintenance Instructions

Installation preparation:

Mount CM572-DP on a 35 mm DIN rail, ensuring 10 mm clearance from adjacent modules for airflow. Verify the AC500 PLC is powered off before connecting the module to the backplane. Use shielded twisted-pair Profibus cable (0.64 mm²) for the D-sub 9-pin connection, grounding the shield at both ends to reduce noise. Connect 24 V DC power (±10%) to the terminal block, checking polarity to avoid damage.

Maintenance suggestions:

Inspect CM572-DP monthly by checking status LEDs—steady green indicates normal operation; red signals faults (e.g., Profibus bus errors). Clean the module’s backplane connector quarterly with compressed air to remove dust, preventing signal degradation. If communication fails, verify Profibus termination resistors (120 Ω) are installed at network endpoints, and check for incorrect data rates. Replace CM572-DP with an ABB-approved spare if the fault persists, ensuring the new module is configured with identical Profibus parameters (address, baud rate).
