645-2 application field and working principle are applied in power system as its own protocol for communications between intelligent electronic devices (IEDs). It is designed for systems such as supervisory control and data acquisition (SCADA), automatic meter reading (AMR), substation automation, power plant automation and distributed control systems.

645-2 protocol makes it possible for different devices with common communication requirement in power system to effectively communicate with each other. It is mainly used for applications such as energy metering, load control, power quality monitoring, etc. It can also be used in public networks, private networks or local area networks.

The working principle of 645-2 protocol is that it performs communication by using the exchange or ordering of data between two or more stations. The information is divided into frames or messages which is then transmitted between the different parties by using a logical address. The information to be exchanged is usually decimal or binary coded and the result of decoding is then available for further interpretation or processing.

The main purpose of 645-2 protocol is to ensure reliable, secure and timely communication between different devices within a network which operates using the protocol. The protocol allows the devices to send data to each other as well as receive data from each other, and also allows the devices to communicate directly with each other.

The protocol also includes the ability for devices to inform each other about their presence in the network or even send commands to another device. This means that a device can send a request to another device for data or information. The request may be sent in the form of an information packet, which contains the information that is required by the requesting device. The protocol allows the devices to communicate securely and quickly, and makes sure that all communications follow a common format.

645-2 protocol also supports the transmission and processing of multiple messages in one go. This allows for the efficient sending and receiving of multiple messages in one session, which is a great advantage in communication. This is especially beneficial when sending and receiving large volumes of data.

In summary, 645-2 protocol is a very useful protocol for communication between different devices in power system. It is designed to ensure reliable and secure communication, while making sure that the information is sent quickly and efficiently. This protocol helps to improve the performance of the power system, and enables the efficient and timely communication between different devices in order to get the best results.
