       The establishment of communication protocol is a necessary key link. Only through remote communication can the dispatching end and the station end realize the information exchange between them. In communication, both sides of communication must follow some established rules when sending and receiving data to ensure the correct and reliable transmission of data. And this protocol is communication protocol.

        In order to solve the incompatibility problem of telecontrol equipment produced by different manufacturers, the fundamental way is to formulate a set of standard communication protocols, and require each manufacturer to comply with them, so IEC61850 standard is formulated.

        After the IEC61850 communication protocol is formulated, in theory, the equipment manufactured by different manufacturers can be connected to the same monitoring system. However, because there are many kinds of protocols commonly used in China, the communication protocols adopted by the equipment of different manufacturers are also different, resulting in the incompatibility of products. Now, even if the same communication protocol is used, However, due to the different strength and technology research and development ability of manufacturers, some manufacturers can not develop a large number of software and hardware for communication protocols. Therefore, IEC61850 protocol converter is needed. Protocol converter is the device to realize protocol conversion.

        Protocol converter generally needs to realize the conversion of communication interface and communication protocol. Protocol converter to link with different devices, communication interface to match with both. The protocol converter needs a network port to connect with the monitoring computer, and one to connect with RS485 or RS232 interface and equipment. In the process of protocol conversion, the protocol converter collects the data of the device and forwards it to the monitoring computer through protocol conversion. On the other hand, it receives the command from the monitoring computer to the device and forwards it to the device to execute the command by protocol conversion.
