The ABB 560CMU02 (ordering code 1KGT012600R0002) is a high-performance Communication Unit (CMU) designed for the RTU560 remote terminal unit series. This module serves as the primary processing and communication hub for substation automation, managing data concentration, protocol conversion, and secure communication between field devices and higher-level SCADA systems.

 

Technical Functionality

The 560CMU02 is equipped with a powerful 32-bit CPU and a real-time operating system to handle complex logic and high-volume data traffic. It supports a wide range of standard protocols (such as IEC 60870-5-101/104, DNP3, and IEC 61850) and features integrated cyber security measures, including encryption and user authentication, to protect critical infrastructure from unauthorized access.

 

Key Specifications

 

Operational Precautions

• Firmware Management: Use the RTUtil560 software tool to ensure the firmware version is consistent across all CMUs in a redundant rack; mismatched firmware can lead to synchronization failures.
• Redundancy Configuration: When used in a redundant pair, ensure the redundancy cables are securely connected and the “Line Switching” parameters are correctly mapped in the configuration logic.
• Storage Media: The module uses a CompactFlash card for project data and firmware; never remove the card while the “Run” LED is active to avoid file system corruption.

 

Common Questions Q&A

Q: Can this module operate as an IEC 61850 Client and Server simultaneously? A: Yes, the 560CMU02 is capable of acting as a gateway, collecting data from IEDs as a client and forwarding it to the SCADA system as a server.

Q: Does it support secure authentication? A: Absolutely. It supports IEC 62351-5 and 62351-3 for secure communication and role-based access control (RBAC).
