IEC 60870-104 Protocol IEC 60870-104 is a widely used protocol for communication between supervisory control and data acquisition (SCADA) systems and remote terminal units (RTUs). IEC 60870-104 is a modern and more advanced protocol compared to IEC 101. It is designed to address the limitations of IEC 101, such as its security vulnerabilities and performance limitations. IEC 60870-104 Protocol Master/Slave Key features and components of IEC 104: Asynchronous serial communication: Similar to IEC 101, IEC 104 uses asynchronous serial communication for data transmission. Master-slave architecture: It also follows a master-slave architecture, where the SCADA system is the master and controls the RTUs. Event-driven data transfer: Unlike IEC 101, IEC 104 uses an event-driven data transfer mechanism. This means that data is only transmitted when there is a change in the status of the remote equipment, rather than on a periodic basis. This improves efficiency and reduces network traff

IEC 60870-101 Protocol  IEC 60870-101 is a widely used protocol for communication between supervisory control and data acquisition   (SCADA)  systems and remote terminal units  (RTUs) . It is particularly common in the energy industry, including power generation, transmission, and distribution. IEC 60870-101 Protocol Master/Slave Key features and components of IEC 101: Asynchronous serial communication: It uses asynchronous serial communication, which is a common method for transmitting data over serial lines, such as RS-232 or RS-485. Master-slave architecture: The protocol follows a master-slave architecture, where the SCADA system acts as the master and controls the RTUs, which are the slaves. Cyclic data transfer: IEC 101 uses a cyclic data transfer mechanism, where the master periodically polls the slaves for data. This ensures that the SCADA system has up-to-date information about the status of the remote equipment. Message types: IEC 101 defines various message types for differ

The difference between IEC 101 vs IEC 104 Communication Protocol IEC 101 and IEC 104 are protocols used for communication between Supervisory Control and Data Acquisition ( SCADA ) systems and Remote Terminal Units (RTUs). However, they differ in several key aspects. Here is the general key between the two types of protocol: IEC 60870-5-101 Cyclic data transfer: IEC 101 uses a cyclic data transfer mechanism, meaning the master (SCADA) periodically polls the slaves (RTUs) for data. Limited security: IEC 101 has limited security features, making it vulnerable to attacks. Older protocol: IEC 101 is an older protocol, developed in the 1970s. IEC 60870-5-104 Event-driven data transfer: IEC 104 uses an event-driven data transfer mechanism, meaning data is only transferred when there is a change in the status of the remote equipment. Enhanced security: IEC 104 has enhanced security features, including encryption and authentication. Modern protocol: IEC 104 is a more modern protocol, develop
