Signal Identification
Elements of the signal identification as defined in IEC 61850–7–2 are illustrated in Figure 7.
Figure 7. Elements of the Signal Identification as Defined in IEC 61850-7-2
The signal designation consists of the following four parts:
1. A user defined part identifying the Logical Device LD in the process (LDName).
2. A function related part to distinguish several LNs of the same class within the same LD/IED (LN-
Prefix).
3. The standardized LN class name and the LN instance number, which distinguishes several LNs
of the same class and prefix within the same LD/IED.
4. A signal identification inside a LN consisting of data and attribute name as defined in IEC 61850–
7–3 and IEC 61850–7–4.
IED Related Naming
The LDName part is built out of the objects IED and LDevice. The LNName is the LN Prefix, the LN class
and the LN instance #.
The LN prefix is used to identify several versions of a LN class. The link between the IED and the primary
process (Substation, Voltage level, Bay) is given in the substation section of the station SCD file but not in
the signal identification in the telegram. The IED name may be extended with a short form of the three
missing levels. See Figure 8.
