Function Embedding in the Device
General
SIPROTEC 5 devices offer great flexibility in the handling of functions. Functions can be individually loaded
into the device. Additionally, it is possible to copy functions within a device or between devices. The necessary
integration of functions in the device is illustrated by the following example.
NOTE
The availability of certain settings and setting options depends on the device type and the functions avail-
able on the device!
Several predefined function packages that are tailored to specific applications exist for each device family. A
predefined functional scope is called an application template. The existing application templates are offered
for selection automatically when you create a new device in DIGSI 5.
Application Template
When creating the device in DIGSI 5, you must specify the hardware configuration of the device. DIGSI 5 then
automatically offers the appropriate 7KE85 application template for the selected hardware configuration.
Select one of the offered application templates.
See also chapter 2.2 Adjustment of Application Templates/Functional Scope.
Function Groups (FG)
Functions are arranged in function groups. This simplifies handling of functions (adding and creating). The
function groups are assigned primary objects, such as feeders with current and voltage transformers. Further-
more, special function group functionalities, such as all recorders (found in DIGSI 5 under Recording), can be
summarized.
The function groups bundle functions with regard to the following basic tasks:
•
Assignment of functions to current and/or voltage transformers (assignment of functions to the meas-
uring points and thus to the fault recorder)
•
Exchange of information between function groups
When a function is copied into a function group, it automatically works with the measuring points assigned to
the function group. Their output signals are also automatically included in the configured interfaces of the
function group.
The selected application template Fault recorder contains 4 function groups:
•
Function group Voltage
•
Function group Voltage/current
•
Function group Recorder
•
Function group PMU
The following tables show the structure of the function groups.
