IEC 60870-5-103 process data

IEC 60870-5-103 data objects

The IEC 60870-5-103 protocol in the IEDs is built on top of the internal IEC 61850
data model. Thus, the IEC 60870-5-103 application data objects and Class 1 events are
derived from IEC 61850 data objects and data set reporting. The IEDs have a
predefined IEC 61850 data set configuration. In other words, it is predefined which
internal data object changes the IEDs detect.
The available IEC 60870-5-103 Class 1 data objects in the IEDs are selected from the
objects predefined in the IEC 61850 data sets. IEC 61850 data set reporting and IEC
60870-5-103 Class 1 event reporting are basically identical.
For a list of the available data objects, see the point list manual.

Indications

The IEC 60870-5-103 standard defines indications to be of ON/OFF type. The value
coding for indications is always DPI, where only values 1 and 2 (binary 01 and 10) are
used. Value 1 means OFF and value 2 means ON. Indications are assigned to IEC
60870-5-103 Class 1 data transactions.
Indications relate to general purpose signals or protection signals (start and trip). The
standard defines two ASDU object types for indications: ASDU 1 and ASDU 2.
ASDU 1 type is intended for general purpose objects and ASDU 2 type for protection
objects. These ASDU types are shown as TypeID 1 and TypeID 2 in the
Communication Management tool of PCM600.
The IEC 60870-5-103 standard was originally defined for protective equipment only.
Therefore the standard does not include circuit breaker control and object definitions.
For circuit breaker and disconnector position information the IEC 60870-5-103 DPI
value is extended to include the values 0 and 3 (binary 00 and 11) also. These values
represent the four-pole object's intermediate and faulty positions.
