ABB RTU560 560CMD11 COMMUNICATION UNIT
The ABB RTU560 560CMD11 COMMUNICATION UNIT is a key component of the RTU560 remote terminal unit, mainly used for remote monitoring, control, and communication in power systems. Here is a detailed introduction:
- Diverse Communication Interfaces: It is equipped with multiple serial interfaces (CP1, CP2, CPA, CPB) that can interface with RS485 or RS232C signals, and two Ethernet 10BaseT/100BaseT LAN interfaces (E1, E2). In addition, it has an integrated GPRS modem (only in the R0011 version), enabling communication via GSM/GPRS. This allows the unit to connect to various external devices and systems through different communication media and protocols, such as direct connection (RS232, RS485), audio modem, wireless connection, dial - up modem, fiber - optic connection, digital network, and LAN/WAN.
- Programmable Function: The module can be programmed, allowing users to write control programs according to specific application requirements to achieve customized control logic. This enables the 560CMD11 to adapt to different application scenarios and control requirements.
- Real - time Monitoring Capability: It has a real - time monitoring function that can monitor the status and operation of external equipment in real - time, detect faults promptly, and send out alarm signals. This is crucial for ensuring the stable operation of power systems.
- Redundant Design: The RTU560 system, of which the 560CMD11 is a part, can be redundantly configured according to customer requirements. This includes redundancy of communication interfaces, central processing units, and power supplies, enhancing the reliability and stability of the system.
The 560CMD11 controls process events and communications with control centers and local MMI systems through its various interfaces. The serial interfaces and Ethernet interfaces receive and send data signals, enabling communication and data exchange with external devices such as sensors, actuators, and upper - level monitoring systems. The integrated GPRS modem (in the R0011 version) allows for wireless data transmission via the GSM/GPRS network, facilitating remote monitoring and control in areas with wireless network coverage.
This communication unit is suitable for remote monitoring, control, and communication applications in power systems. It can achieve flexible control and monitoring of external equipment, improve the operating efficiency and reliability of the system, and is particularly suitable for industrial automation, remote supervisory control, and data acquisition (SCADA) systems.
