Section 3 Vendor-specific implementation
3.1 Product series implementation
IEC 60870-5-103 is specified for single function protective equipment with a limited
set of process data. Some extensions are necessary for supporting the IEDs.
• Multiple protection functionality
• Objects with four valid positions such as circuit breakers or disconnectors
• Circuit breaker and disconnector control operations
• Class 1 event overflow handling
Since these features are not a part of the IEC 60870-5-103 standard, it is not likely that
different vendors have implemented them in the same manner. However, it is
guaranteed that the IEDs in this product series are equally implemented concerning
these features. In addition of having product series-specific default settings for private
function type and information number application data definitions, the user can
reprogram these settings if required. The user can also affect the way in which Class
1 event overflows should be treated and reported.
ASDU type 2 data is generally supported. This means the generation of a fault number
and a relative time stamp for protection related Class 1 events. Despite the default
ASDU type settings it is possible for the user to configure either ASDU type 1 or 2
separately for each private Class 1 data.
Different Class 2 measurand value sets are selectable. All the standardized ASDU 3
(Meas I) and ASDU 9 (Meas II) sets can be selected. Additionally some IED-
dependent private ASDU 9 frames are also provided. It is also possible for the user to
freely define an own (private) Class 2 measurand set.
IEC 60870-5-103 disturbance files are supported. The IEC 60870-5-103
communication stack adapter contains a conversion functionality between the IED's
native disturbance recorder files and the IEC 60870-5-103 specific disturbance
recorder data and settings definitions.
3.2 Communication link
The IEC 60870-5-103 protocol can only operate on a serial communication link. The
standard defines serial data characteristics.
