Communication manager Introduction SPC3000 series communication manager is a high integrated new 32bit embedded intelligent communication device. It is used to collect information of whole substation automation system and centralized send to local back-end or remote debug centre, and at the same time transfers the orders of back -end and centers to all measure and control devices that realize local and remote control. SPC directly collect all on -site device data in small sized automation system, and transfer to background control system by user required communication protocol( 101,104,CDT and so on)and communication medium(Ethernet,RS232/422/485 and so on) to finish all on-site monitoring. In big systems, it can be as function substation and bay level that make all levers related to realize data transferred through different classification and directions. Features To adopt Motorala 32-bit high performance microcontrollers and commercial real-time multifunction operating system that makes sure of the product stability and operation speed. High quality industrial element, high lever electrical design and high density integrated circuit structure enable the device have excellent electro-magnetic shielding and electrical isolation. The integrated machine has no adjustable element that greatly enhances the ability of anti-interference and the reliability of the device. Adopt good performance switch power to the device, input voltage is DC 110~340V or AC 85~264V, output voltage is 5V, wide-range voltage output can widely be used for different power supply environment. Having high speed and reliable communication interface such as Ethernet and serial port and CAN for system extension to strengthen the device scalability and allocation flexibility. Flexible on-line and off-line debugging, reliable program upgrading and parameter download and data query functions meet the need of ever new and faster network information age. Be provided with great ability of self -diagnosis and self -healing, the system can be self-recovered in a short time when causing program operation error by outside interference or other reasons. Provide secondary development kit, on the basis of supporting CDT, Polling, Modbus, DNP 3.0, 1801,IEC870-5-101/102/103/104 an
