IEC 60870-5-104 Protocol

Introduction to IEC 104

IEC 60870-5-104 (IEC 104) is a standard for telecontrol, teleprotection, and associated telecommunications for electric power systems. It defines a network-access for IEC 60870-5-101 using a complete TCP/IP based interface. This protocol is used for monitoring and controlling geographically widespread processes.

Key Features

• Based on TCP/IP, which ensures reliable, connection-oriented data transmission.
• Supports both balanced (master-master) and unbalanced (master-slave) transmission.
• Provides mechanisms for time synchronization.
• Uses a standardized format for data, ensuring interoperability between devices from different vendors.
