Product Overview
The ABB 560CMR01 R0001 (ordering code 1KGT036200R0001) is a Communication Unit (CMU) module belonging to ABB’s RTU560 remote terminal unit product line, designed to serve as the central processing and communication engine for substation automation and remote monitoring applications. As the “brain” of the RTU560 rack, the 560CMR01 R0001 manages all I/O modules via the serial peripheral bus (SPB), reads process events from input modules, issues commands to output modules, and handles time synchronization across the entire station. The module is built around an ARM Cortex-A8 AM3352 processor running at 800 MHz, paired with 128 MB of RAM and 8 MB of boot flash, providing deterministic performance for time-critical SCADA and telecontrol tasks.
The 560CMR01 R0001 is distinguished from its sibling variant, the R0002, by its standard cybersecurity feature set rather than the advanced security chip configuration. This makes the 560CMR01 R0001 suitable for installations where baseline network protection is sufficient and where compatibility with existing RTU560 architectures is the priority. The module communicates with control systems and local HMIs through two Ethernet ports (10/100BaseT) and two configurable serial ports (RS-232 or RS-485), supporting protocols such as IEC 60870-5-101/103/104, DNP3, and Modbus—though protocol licenses are generally purchased separately. A battery-buffered real-time clock (RTC) maintains precise timekeeping during power interruptions, ensuring that Sequence of Events (SOE) records retain accurate millisecond-resolution timestamps for post-fault analysis.
