Communication Unit 560CMR01

RTU560 product line

Communication module for RTU560 with 32 bit

CPU
• 2x serial communication interface (RS-232 or
RS-485) for remote communication
• 2x Ethernet interface (10/100BaseT)
• 1x USB port
• 1x serial peripheral bus
• Battery buffered real time clock

Application
The 560CMR01 communication unit is one of the CMU E1 E2 CP1, CP2
10/100 MB LAN 10/100 MB LAN RS232C or RS485
modules of the RTU560 product line.

The essential tasks are:

• Managing and controlling of the RTU560 product line I/ Ethernet Ethernet
O modules via the interface to the serial I/O bus. Controller Controller

• Reading Process events from the input modules.

• Sending commands to the output modules.
• Communicating with control systems and local HMI
systems via the serial interface and the Ethernet Processor bus
interfaces.
• Communication with Sub-RTU’s, IED’s or multimeter
devices via the serial interface and the Ethernet Serial line MPU RAM/Flash
interfaces. interface ARM cortex A8 Memory

• Managing the time base for the RTU560 product line

character based communication protocols.
Characteristics
The unit has a battery buffered real time clock (RTC).
On the applied ARM cortex A8 controller AM3352 a real-
The unit is available in two versions: time operating system is implemented. The 560CMR01
• 560CMR01 R0001 with standard cyber security is responsible for the interface management, the event
functions handling, the time base and the internal data base. The
• 560CMR01 R0002 with security chip supporting high- controller acts as master for the SPB I/O bus (serial
demanding cyber security use cases peripheral bus). RTU560 synchronizes itself to the time
references supplied by 560RTC0x. The time information
of the 560RTC0x is provided to the 560CMR01 on the
backplane of the sub-rack.

System relevant configuration files are stored in the non-

volatile flash memory card (removable SD-card™) in order
to guarantee a valid system configuration after Power on
Reset (PoR).

A battery buffered RTC is used to keep an exact time

during power off state.

The communication unit provides the following interfaces:

• Communication Port 1 and 2 (CP1 & CP2): serial
interfaces according RS232C or RS485 with RJ45
connectors. The communication ports can be
configured independant as SPB I/O bus interface to
the front.
• Ethernet interface 1 and 2 (E1 & E2): 10/100BaseT
with RJ45 connector.
• USB 2.0 device interface for diagnosis and
maintenance purposes.
• The SPB I/O bus is directly connected to the
backplane connector.
