Text Structure and Reference Number for Settings and Indications
Each parameter and each indication has a unique reference number within every SIPROTEC 5 device. The
reference number gives you a clear reference, for example, between an indication entry in the buffer of the
device and the corresponding description in the manual. You can find the reference numbers in this docu-
ment, for example, in the application and setting notes, in the logic diagrams, and in the parameter and infor-
mation lists.
In order to form unique texts and reference numbers, each function group, function, function block/stage, and
indication or parameter has a text and a number. This means that structured overall texts and numbers are
created.
The structure of the texts and the reference numbers follow the hierarchy already shown in Figure 2-1.
•
Function group:Function:Stage/Function Block:Indication
•
Function group:Function:Stage/Function Block:Parameter
The colon serves as a structure element to separate the hierarchy levels. Depending on the functionality, not
all hierarchy levels are always available. Function Group and Stage/Function block are optional. Since the func-
tion groups, functions as well as tripping stages/function blocks of the same type can be created multiple
times, a so-called instance number is added to these elements.
EXAMPLE
The structure of the text and reference number is shown in the protection-function group Line as an example
of the parameter Threshold value and the indication Pickup of the 2nd definite time-overcurrent protec-
tion stage of the function Overcurrent protection, phases (see Figure 2-9). Only one function and one func-
tion group exist in the device. The representation of the stage is simplified.

Figure 2-9 Stage of the Overcurrent Protection Function, Phases (without Representation of Stage
Control)
The following table shows the texts and numbers of the hierarchy elements concerned:
Name Number of the
Type
Instance Number
Protection function group Line 2 1
Function Overcurrent 3ph 20 1
Stage Definite time-overcurrent
protection
66 2
Settings Threshold value 3 –
Indication Pickup 55 –
The instance numbers arise as follows:
•
Function group: Line 1
1 instance, because only one Line function group exists in the device
•
Function: Overcurrent 3ph 1
1 instance, because only one Overcurrent 3ph function exists in the Line function group
