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

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.

I/O Controller (IOC)

The microcontroller on the module handles all critical tasks for the parameterized processing functions. In addition, it communicates interactively with the RTU I/O bus.

All configuration data and processing parameters are loaded by the communication unit via the RTU I/O bus.

The module is equipped with a serial interface to the RTU560 I/O bus on the backplane.

The binary output unit performs the following processing functions for individual signal types:

– Control of command output duration

Command monitoring function:

– Checking of output relays on the module (m out of 16)

– Monitoring of the output bit pattern by reading back the output status

– Monitoring of the switching voltage before and during output (24 V DC coil voltage)

– Command output duration monitoring

During initialization and operation, the module performs a series of tests. If a fault occurs, it will be reported to the communication unit.

All fault conditions affecting the function of the module are signaled as common faults by the red LEDs. Module faults are detected by the communication unit.

Binary outputs

The binary outputs utilize relay contacts.

The 16 outputs are divided into two groups. Each of the 8 outputs has a common circuit. The groups are isolated from each other and from the internal electronics.

The relay coil supply voltage (24 VDC) is switched by an internal relay (R17).

The relay coil supply voltage (24 VDC) is monitored internally before and during the command output.

Command outputs to the process equipment can be executed either directly or in conjunction with the command output monitoring module.

The command output monitoring module is responsible for checking the output circuits (1 out of n times). For more details, refer to the Command Output Monitor datasheet.

The following modules with command output monitoring functions are supported:

– 23BA23 (60 VDC maximum)

The 1.5-pole command output can only be used in conjunction with the command output monitoring module. When using the 1.5-pole command output, the

One of the output relays of the 560BOR01 switches the command to the intermediate relay. Process voltage of the intermediate relay

The process voltage of the intermediate relay is switched by the command output monitoring module.

For 2-pole commands, two output relays are required for each command.

Alternatively, using additional booster relays connected to the command output monitoring module 23BA23.

Direct switching of process relays with high switching capacity on electrical devices (disconnectors, circuit breakers) (see data sheet 23BA23).

The module 560BOR01 performs several command monitoring functions before and during command output.

These tests ensure correct output. These tests can be further refined with the Command Output Monitoring module.

If the command monitoring reveals a fault, the command is canceled. Release relay R17 will only energize the output relay if the test is successful.

A faulty drive or a faulty release relay R17 will result in a complete failure of the command output module.
