ABB Communication Unit 560CMR02 Remote Terminal Unit

Remote Terminal Unit - Datasheet

Communication Unit 560CMR02 RTU560 Product Family

RTU560 communication module CPU with 32-bit CPU

- 6 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 560CMR02 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.

The board occupies two slots in the RTU560 chassis.

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

The ARM cortex A8 controller AM3352 is used to implement the real-time operating system. 560CMR02 is responsible for the interface management, event processing, and internal database.

The 560CMR02 is responsible for interface management, event processing, 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 560CMR02 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 ... Communication ports 1 ... 6 (CP1 ... Communication ports 1 ... 6 (CP1 ... CP6): RS232C or RS485 serial interface with RJ45 connector CP1 and CP2 can be configured independently of each other 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.
