IEC101 Insights

What is IEC101?

IEC 60870-5-101, often referred to as IEC101, is a communication protocol used for telecontrol, teleprotection, and associated telecommunications for electric power systems. It is commonly used for serial communication between a control station (master) and substation devices (slaves) like remote terminal units (RTUs) and intelligent electronic devices (IEDs). It defines the structure of data exchange, error checking mechanisms, and communication procedures for transmitting information such as status indications, measurements, and control commands.
