Finally, explains briefly the following task. Embedded Multiply Port Modbus Server acts as the middle tier business platform—could supervisory and control the various types of field control devices through 8 RS422/RS485 buses, provide standard Modbus protocol based on TCP/IP, accomplishes the ESP SCADA system with remote control and independent of distance. At the same time, acts as the agency of field control level and DCS system, makes the various types of field control devices integrate with DCS system through standard industrial protocol. So, eMPMS extends the application range and flexibility of the ESP SCADA system, accelerate the efficiency of the ESP system, and plays a positive role in environment protection and the decrease of power plant`s dust emission.
