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. The 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 section
Interoperability
in this manual for the interoperability list.
Data mapping principle
Whenever possible, process data is mapped into standard IEC 60870-5-103
function types and information numbers. When this is not possible the process data
is mapped into private function types and information numbers. General principle
of the mapping is to keep all process data belonging to the same function design
inside the same IEC 60870-5-103 function type definition. However, if this default
mapping principle causes interoperability problems with older installations, the
user can freely remap every available IEC 60870-5-103 process data point by using
PCM600.

Example of IEC 60870-5-103 communication structure for a
substation automation system
IEC 60870-5-103 communication protocol is mainly used when a protection IED
communicates with a third party control or monitoring system. This system must
have software that can interpret the IEC 60870-5-103 communication messages.
