ABB 560CMU80R1  1KGT008800R0001 is the core communication and control module of the ABB RTU560 series Remote Terminal Unit (RTU). It features data acquisition, protocol conversion, edge computing and multi-link redundant communication. It is widely applied in SCADA systems and distributed control systems for critical infrastructure such as power, water conservancy, oil and gas industries.

Product Advantages

Industrial-grade High-reliability ArchitectureWide temperature range (-20℃ ~ +70℃), excellent EMC electromagnetic interference resistance, and coated PCB with moisture and dust protection, suitable for harsh environments of substations and field stations.Multi-protocol Fusion GatewayNatively supports IEC 60870‑5‑101/104, DNP3.0, Modbus RTU/TCP. It enables protocol conversion between serial ports and Ethernet, reducing integration costs of heterogeneous systems.Real-time Edge Processing CapabilityEquipped with 32-bit ELAN 400 processor (66MHz) and 4MB DRAM (expandable to 16MB). It supports local logical operation, event preprocessing and data caching to reduce the load on the host computer.Flexible Redundancy and ExpansionDual Ethernet plus multi-serial port configuration supports network redundancy and link backup. The modular design allows on-demand expansion of I/O and communication daughter cards.

Operation Guide

1. Installation and Wiring

• RS232: Cross-connect TX/RX/GND; default baud rate is 9600bps.
• RS485: Differential connection for Line A and Line B; enable 120Ω terminal resistor.
• Ethernet: Connect RJ45 port to switch; default IP address: 192.168.1.1.
• Bus Wiring: Connect SPB/WRB bus to I/O modules and confirm correct DIP switch address setting.

2. Configuration Steps

• Serial Port: Select RS232/RS485, configure baud rate, data bits, parity bit and stop bits.
• Ethernet: Set static IP, subnet mask and gateway; enable redundancy if required.

• Master Station: IEC 60870‑5‑104 master station for connection to SCADA server.
• Slave Station: Modbus RTU slave station for connection to PLCs and meters.
