Overview
Essential details：520CMD01 RTU520 product line Communication unit
The 520CMD01 communication unit is the CMU module of the RTU520 product line.
The essential tasks are:
• Managing and controlling of the RTU520 I/O modules via 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 interface.
• Communication with Sub-RTU’s, IED’s or multimeter devices via the interfaces (RS485) and the Ethernet interface.
• Managing the time base for the RTU520 product line station and synchronizing the I/O modules.
• Handling the dialog between RTU520 product line and Web-Browser via the LAN interfaces.
The communication unit will be mounted on a DINrail, together with the power supply module and the I/ O modules. The communication unit is able to handle Ethernet- and UART character based communication protocols.
The unit is available in 2 versions:
• R0001: without battery buffered real time clock (RTC)
• R0002: with battery buffered real time clock (RTC)

520CMD01 RTU520 product line Communication unit
On the applied ARM9 controller AT91SAM9260 a realtime operating system is implemented. The 520CMD01 is responsible for the interface management, the event handling, the time base and the internal data base. The controller acts as master for the serial I/O bus (WRB).
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).
An optional battery buffered RTC is used to keep an exact time during power off state.
The communication unit provides the following interfaces:
• Communication Port 1 (CP1): a serial interface according RS232C with RJ45 connector.
• Communication Port 2 and 3 (CP2 & CP3): serial interfaces according RS485 with RJ45 connector.
• Ethernet interface (E1): 10/100BaseT with RJ45 connector.
• Interface X1 for power supply to the power supply unit 520PSD01.
• Interface X2 for communication unit with the RTU520 I/ O modules.
• USB 2.0 device interface for diagnosis and maintenance purposes.
• WRB I/O bus interface for local communication with the I/O-modules
