Taking DC traction power supply system as an example, a communication mode based on Modbus is proposed. Based on the analysis of interior communication data on DC traction power supply system, the serial communication between SCADA and microprocessor protection equipment and S7-200 is realized based on modbus protocol of the RS485 interface. The communication of all modules of system interior is reliably accomplished, simultaneity the whole efficiency and security of system are improved.
