Section 2 IEC 60870-5-103 overview2.1 IEC 60870-5-103 standard GUID-69BA3944-3809-43D0-A558-55FA2B87319B v7IEC 60870-5-103 is defined as a companion standard for the informative elementof protection equipment. While the official IEC 60870-5-103 standard dates backto 1997, the protocol has its roots in the VDEW6 communication protocol from thelate 1980’s. A VDEW6 device can be seen as a subset of an IEC 60870-5-103device but not the opposite.IEC 60870-5-103 defines communication for a serial, unbalanced link only.Communication speeds are defined as either 9600 or 19200 baud.Standard documentationThis manual assumes that the reader has some basic knowledge of the IEC60870-5-103 protocol and the standard IEC 60870 documents relating to theprotocol.Table 1:Standard IEC 60870 documents relating to IEC 60870-5-103IEC 60870document partDescription5-1 Transmission frame formats5-2 Link transmission procedures5-3 General structure of application data5-4 Definition and coding of application information elements5-5 Basic application functions5-6 Conformance testing guidelines5-103 Companion standard for the informative interface of protection equipment.The IEC 60870-5-1…6 parts are also used in communication protocols like IEC60870-5-101 and IEC 60870-5-104.Interoperability and interchangeabilityAn IEC 60870-5-103 device can be interoperable and interchangeable, or onlyinteroperable. Interoperability means that any required application data in thedevice, which can be coded into an IEC 60870-5-103 data type, can be mapped intothe IEC 60870-5-103 address space. This data is recognized by any IEC60870-5-103 master.Interchangeability means supporting the application data (informative elements)whose semantics are pre-defined by the IEC 60870-5-103 standard.
