560CMU05 R0001  Communication module for RTU560

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

The 560CMR01 communication unit is one of the CMU modules of the RTU560 product line.
The essential tasks are:
• Managing and controlling of the I/O modules via the interface to the serial I/O bus.
• Reading Process events from the input modules.
• Send commands to the output modules.
• Communicating with control systems and local HMI systems via the serial interfaces (RS232) and the
Ethernet 10/100BaseT interfaces.
• Communication with Sub-RTU’s, IED’s or multimeter devices via the interfaces (RS485) and the Ethernet interfaces.
• Managing the time base for the RTU560 product line station and synchronizing the I/O modules.
• Handling the dialog between RTU560 product line and
Web-Browser via the LAN interfaces.
Within the RTU560 racks the board occupies . The communication unit is able to handle Ethernet- and UARTcharacter based communication protocols.
The unit has a battery buffered real time clock (RTC).
The unit is available in 2 versions:
• R0001: with standard cyber security functions
• R0002: with security chip for advanced cyber security functions

560CMU05 R0001

On the applied ARM cortex A8 controller AM3352 a realtime operating system is implemented. The 560CMR01
is responsible for the interface management, the event handling, the time base and the internal data base. The
controller acts as master for the SPB I/O bus (serial 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 nonvolatile 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.
