Description

The ABB 560CMU05 is a versatile and robust communication and management unit from the renowned ABB S+ (Symphony Plus) family, specifically designed for the Harmony/INFI 90 open control system. This module serves as a critical node for integrating older INFI 90 hardware with modern plant networks and higher-level systems. The core function of the ABB 560CMU05 is to act as a powerful gateway and network interface, facilitating seamless data exchange between the control processors (e.g., CP40, CP60) and external devices such as engineering workstations, operator stations, and plant-wide DCS or SCADA systems. It manages the high-speed peer-to-peer communication (INFI-NET) between modules within a rack and across the broader control network, ensuring deterministic and reliable data transfer for complex process control applications. The ABB 560CMU05 is an essential component for modernizing and extending the life of existing INFI 90 systems, providing the necessary connectivity for advanced monitoring, data historization, and asset management while preserving the integrity and reliability of the original control strategy.

Main Features and Advantages

The ABB 560CMU05 is engineered for high availability and seamless integration, which are critical for continuous process operations. Its most significant feature is its role in managing the INFI-NET ring network, a deterministic, token-passing network that provides high-speed, peer-to-peer communication between all nodes in the system. This ensures reliable and timely data exchange, which is the backbone of coordinated control across large plants. The module acts as a gateway, allowing legacy INFI 90 systems to connect to modern Ethernet-based plant networks, thereby bridging the gap between proven control hardware and contemporary data acquisition needs. This functionality provides a major advantage: it protects existing capital investment in INFI 90 infrastructure while enabling access to real-time process data for performance monitoring, advanced analytics, and centralized operator supervision. The robust design of the 560CMU05 ensures high mean time between failures (MTBF), contributing to the overall availability and longevity of the control system it serves.

Application Field

The application of the ABB 560CMU05 is predominantly found in large-scale, continuous process industries where ABB’s Harmony/INFI 90 systems were historically deployed. This includes fossil fuel and nuclear power generation plants, where it is used for boiler control, turbine control, and balance-of-plant systems. It is also extensively used in chemical processing, oil and gas refineries, pulp and paper mills, and water/wastewater treatment facilities. In these environments, the 560CMU05 is installed in distributed control nodes throughout the plant. Its primary role is to ensure that data from these remote processing units is reliably aggregated and made available to central operator consoles and engineering stations. It is indispensable for systems that require reliable data highway communication for coordinated control loops and sequences that span multiple controllers, making it a vital component for maintaining the operational integrity and efficiency of some of the world’s most critical industrial processes.
