The IEC 60870-5 family defines based on the five basic standards IEC 60870-5-1 (frame formats), -2 (link transmission procedures) -3 (structure application data), -4 (information elements) and -5 (basic application functions)
the companion standards IEC 60870-5-101, -102, -103 and -104.
The IEC 60870-5 protocol family is used widely throughout Europe.
IEC 60870-5-104 is used as a general transmission protocol between a control system and substations (RTUs, Remote Terminal Units). It possesses general features within the context of SCADA applications.
The messages can only be transmitted through the internet protocol TCP/IP. Because TCP/IP is already a reliable transmission protocol, a link layer is not required.
