IEC 60870-5-103 overview

IEC 60870-5-103 standard

IEC 60870-5-103 is defined as a companion standard for the informative element
of protection equipment. While the official IEC 60870-5-103 standard dates back
to 1997, the protocol has its roots in the VDEW6 communication protocol from the
late 1980's. A VDEW6 device can be seen as a subset of an IEC 60870-5-103
device 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 documentation
This manual assumes that the reader has some basic knowledge of the IEC
60870-5-103 protocol and the standard IEC 60870 documents relating to the
protocol.

The IEC 60870-5-1...6 parts are also used in communication protocols like IEC
60870-5-101 and IEC 60870-5-104.
Interoperability and interchangeability
An IEC 60870-5-103 device can be interoperable and interchangeable, or only
interoperable. Interoperability means that any required application data in the
device, which can be coded into an IEC 60870-5-103 data type, can be mapped into
the IEC 60870-5-103 address space. This data is recognized by any IEC
60870-5-103 master.
Interchangeability means supporting the application data (informative elements)
whose semantics are pre-defined by the IEC 60870-5-103 standard. However, only
