8.1.5.3.3 Images

Images are real objects of the plant with parameters and signals (examples: feeder north, cir-
cuit breaker Q00, disconnector Q10).
·
Typified images
Typified images can be created from the defined types, that means, each images is as-
signed to a type. The assigned type defines thereby the structure for the image. The struc-
ture defines which linktypes include a signal and which parameter includes a link. This
structure can be changed only in the type of the belonging image. All images that are as-
signed to that type, adopt automatically the structure change (inheritance). The same be-
havior applies for default input.
The usage of typified images is the more efficient, the more identic images are present.
·
Typeless images
Typeless images do not have a reference to the types, that means, no inheritance takes
place. Typeless images are also created by structural changes of a typified image (since
the image does not have the same structure as the type).
Typeless images are advantageous, if images are only uniquely existing.
Below typless images, typified images can be used (example: voltage level "20 kV" is
typeless since it is only uniquely existing, all feeders thereunder are typified images).
·
Link images
In the link images the parameters of the single target devices can be set.
The signals of the libraries include as first link a so-called common link (LNK_ADR). There
reside parameters (example: longtext, LAN station...) that include "references" to other
links of the same signal or are source of "formulas".
A reference causes that upon changes of an entry in the common link the change takes
place automatically in the link of the specific target device. Message address CASDU(1,2),
IOA(1,2,3) and TI are generated automatically with filling of the 1703 link address
(Lk_Reg, Lk_Komp, Lk_BSE, Lk_ZSE, Lk_DP) by means of formulas and references and
do not have to be entered.
You find the instruction for the creation of images in the SICAM TOOLBOX II Online Help,
chapter "OPM II", section "Images".
Parameterization of the Process Signals and Assignment to the System Technique
The parameters for the technological processing of process signals reside in the directory tree
below the link images:
·
Addressing
·
Signal preprocessing
·
Signal postprocessing
You find the description of the parameters in the SICAM TOOLBOX II Online Help, chapter
"Parameter Documentation".
You find the description of the technological processing of inputs and outputs of the process
periphery in the manual SICAM RTUs Common Functions Peripheral Elements According to
IEC 60870-5-101/104.
The assignment of a process signal to a hardware pin or software data point in the system
technique takes place by means of assignment (alternatively automatical or manual). You find
the instruction thereto in the SICAM TOOLBOX II Online Help, chapter "Parameter Documen-
tation", section "Assign".
