Text Structure And Reference Number For Parameter And Indications - Siemens SIPROTEC 5 Manual

2.4 Text Structure and Reference Number for Parameter 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 test and reference numbers, every function group, function, function block, and indi-
cation or parameter has a text and a number. This means that structured overall texts and numbers are
created.
The structure of the text and reference number is in accordance with the hierarchy, already shown in chapter
2.1 Function Embedding in the
•
Function group:Function:Function Block:Indication
•
Function group:Function: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 Function block are optional. Since the same type
of function groups, functions as well as function blocks can be created several times, a so-called instance
number is added to these elements
EXAMPLE
The structure of the text and reference number is shown for the parameter dM/dt rise active and the
indication Health of the function Voltage trigger in the VI 3-phase function group. Function and function
group are only present once in the device (in the DIGSI 5 library). The representation is very simplified.

The following table shows the text and numbers of involved hierarchy elements:
Function group
Function
Function block
Parameter
Indication
The instance numbers result from the following:
•
Function group: VI 3-phase 1
1 Instance, because only one function group VI 3-phase exists in the device
