Configuration & Setup
This chapter describes the configuration of the IEC60870-5-104 protocol implementation
into the
DinBox RTU M4
.
IEC 60870 part 5 [1] is one of the IEC 60870 set of standards which define systems
used for telecontrol (supervisory control and data acquisition) in electrical engineering
and power system automation applications.
In practice it is used by a SCADA system to obtain information from RTU’s and PLC’s in
the field. This works on a master/slave principle, where the SCADA system functions as
the master, and the RTU or PLC as the slave.
The IEC 60870-5-104 protocol uses a number of acronyms in describing data types and
addressing. The configuration of IEC 60870-5-104 features in this manual uses the
following protocol terms:
ASDU
Application Service Data Unit
A data item at the application layer of a IEC 60870-5 protocol
ASDU Type ID
ASDU Type Identifier
IEC 60870-5-104 protocol numeric identifier for the ASDU type.
IOA
Information Object Address
The IEC index (address) of the data item.
See the
DinBox RTU M4
CI Guide document for more information about the used ASDU
and ASDU types. The IOA of the different ASDU's can be freely changed, see next
chapters.
