Abstract: IEC 870-5-101 and DNP are two dominant telecontrol protocols. Inorder to deepen the understanding and help the selection and use of the relevant products and devices, detail descriptions are given on their functions, structure and standardization. They both provide data transmission and control functions for SCADA system, according to EPA model. They have many differences in layer definition, especially the data-link layer and application layer. Each has advantages with the consideration on content, implementation and application scope. The topologic structure of telecontrol system and the application environment should be analyzed for choosing one from the two protocols.
