IEC 60870-5

IEC 60870-5 provides a communication profile for sending basic telecontrol messages between two systems, which uses permanent directly connected data circuits between the systems. The IEC Technical Committee 57 (Working Group 03) have developed a protocol standard for Telecontrol, Teleprotection, and associated telecommunications for electric power systems. The result of this work is IEC 60870-5. Five documents specify the base IEC 60870-5:
* IEC 60870-5-1 Transmission Frame Formats
* IEC 60870-5-2 Data Link Transmission Services
* IEC 60870-5-3 General Structure of Application Data
* IEC 60870-5-4 Definition and coding of Information Elements
* IEC 60870-5-5 Basic Application Functions

The IEC Technical Committee 57 has also generated companion standards:
* IEC 60870-5-101 Transmission Protocols, companion standards especially for basic telecontrol tasks
* IEC 60870-5-102 Companion standard for the transmission of integrated totals in electric power systems (this standard is not widely used)
* IEC 60870-5-103 Transmission protocols, Companion standard for the informative interface of protection equipment
* IEC 60870-5-104 Transmission Protocols, Network access for IEC 60870-5-101 using standard transport profiles
