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 a very limited set of
application data informative elements has been defined by the standard. It should also be
noticed that these sets of data are mainly defined for a single function protection IED. 650
series IEDs in turn are multifunctional protection and control IEDs whose internal data model
is based on the IEC 61850 standard.
Interoperability list
The standard requires the IEC 60870-5-103 device to provide an interoperability list, which
actually is more an interchangeability list. See the vendor specific implementation section in
this manual for the interoperability list.
