ABB Communication Unit 560CMR01 RTU560 Product Family

Communication module for RTU560 with 32-bit CPU

- 2 serial communication interfaces (RS-232 or RS-485) for remote communication

- 2 Ethernet interfaces (10/100BaseT)

- 1x USB port

- 1x serial peripheral bus

- Battery buffered real-time clock

Applications

The 560CMR01 Communication Unit is one of the CMU modules of the RTU560 product family.

Its main tasks are

- Managing and controlling the I/O modules via the serial I/O bus interface.

- Read process events from the input modules.

- Send commands to the output modules.

- Communicate with the control system and the local HMI system via the serial interface (RS232) and the Ethernet 10/100BaseT interface.

- Communicates with sub-RTUs, IEDs, or multimeter devices via interface (RS485) and Ethernet interfaces.

- Manages the time base of RTU560 product line stations and synchronizes I/O modules.

- Handles the dialog between the RTU560 product line and a web browser through the LAN interface.

Within the RTU560 chassis, the board occupies . The communication unit handles communication protocols based on Ethernet and UART characters.

The unit is equipped with a battery-buffered real-time clock (RTC).

The unit is available in two versions:

- R0001: with standard network security

- R0002: with security chip with advanced network security features

Features

A real-time operating system is implemented using the ARM cortex A8 controller AM3352. 560CMR01 is responsible for interface management, event processing, time base and internal database.

The 560CMR01 is responsible for interface management, event processing, time base and internal database. The controller acts as a master for the SPB I/O bus (Serial Peripheral Bus).

The RTU560 is synchronized with the time base provided by the 560RTC0x. time information from the 560RTC0x is provided to the 560CMR01 on the subrack backplane.

System-related configuration files are stored on a non-volatile flash memory card (Removable SD Card™) to ensure that the system configuration is valid after a power-on reset (PoR).

The battery buffer RTC is used to maintain accurate time in the event of a power failure.

The Communication Unit provides the following interfaces:

- Communication Ports 1 and 2 (CP1 and CP2): RS232C or RS485 serial interfaces with RJ45 connectors. The communication ports can be independently configured as SPB I/O bus interfaces for the front end.

- Ethernet Interfaces 1 and 2 (E1 and E2): 10/100BaseT with RJ45 connectors.

- USB 2.0 device interface for diagnostics and maintenance.

- The SPB I/O bus connects directly to the backplane connector.
