Provides the mnemonic elements library of the user interface of the industrial automation.
|
The library is created to provide mnemonic elements of the user interface and it contains graphic elements, often need when forming the user interface of the automation of technological processes. The library is built on the basis primitives of the widgets and the internal programming language JavaLikeCalc.
The element's names and their parameters are available in languages: English, Ukrainian and mRussian. Their source code wrote in the human-language independent mode with calls for the translations by the function tr() and the message's translation also allowed for English, Ukrainian and mRussian.
For connection the library to a project of the OpenSCADA station you can obtain the database file as:
- supplied with a ready and proper package of the Linux distribution like to "openscada-libdb-vca", "openscada-LibDB.VCA";
- directly taken for most actual one from the subversion repository and converted to the DB SQLite file in the way:
wget http://oscada.org/svn/trunk/OpenSCADA/data/LibsDB/vcaBase.sql
sqlite3 -init vcaBase.sql vcaBase.db .exit
- downloaded for the one attached here.
This obtained file next you can place into the project directory of the station and create the database object for the DB module "SQLite", registering the database file in the configuration.

1 Passive screen elements
1.1 Elements of pipelines without the gradient fill
The elements in Figure 1.1 serve to construct pipelines of any complexity, required width and color. By default, they are filled in yellow, the rotation angle is 0° and the mirroring disabled.
The pipeline elements include, from the left to the right:
| Name (identifier) | Version | License | Author |
|---|---|---|---|
| Pipe-cross (El_Krest) | 1.0 | GPLv2 | Maxim Lysenko |
| Pipe-line horizontal (El_Pipe_simple) | 1.0 | GPLv2 | Maxim Lysenko |
| Pipe-line vertical (El_Pipe_simple_vert) | 1.0 | GPLv2 | Maxim Lysenko |
| Arrow (El_Strela) | 1.0 | GPLv2 | Maxim Lysenko |
| Back arrow (El_Obr_Strela) | 1.0 | GPLv2 | Maxim Lysenko |
| Pipe-angle (El_pipe_1) | 1.0 | GPLv2 | Maxim Lysenko |
| Pipe-tee (El_Troinik) | 1.0 | GPLv2 | Maxim Lysenko |
Using — development
These widgets can be used by the developer to create mnemonic schemes of the plain pipelines. By the attribute "Color 1" you can change the element filling color. By rotation and mirroring these widgets you can get all the needed combinations. By scaling, you can set the desired pipe width where, for straight sections, the "x" and "y" axis scales may be different, determining the typical pipe width on the mnemonic scheme and the length of its individual section, respectively. To use it you need to add selected ones to a mnemonic scheme, systematically adjust for the geometry and visually connect the needed parts of the pipelines properly, see Addition 1 for the details. For the purpose of systematic and simplified work, you may prepare only first elements and for other pipeline parts use ready copies of these already prepared and placed elements.
Using — runtime
In the runtime mode, these elements look the same as in the development mode because they are not dynamic.
1.2 Elements of pipelines with volumetric filling
The elements in Figure 1.2 serve to construct volumetric pipelines of any complexity, required width and color. By default, the transparent volumetric gradient is filled in yellow.

Using — development
These widgets can be used by the developer to create mnemonic schemes of the volumetric pipelines. By the attribute "Fill: color" you can change the element filling color. By scaling, you can set the desired pipe width where, for straight sections, the "x" and "y" axis scales may be different, determining the typical pipe width on the mnemonic scheme and the length of its individual section, respectively. To use it you need to add selected ones to a mnemonic scheme, systematically adjust for the geometry and visually connect the needed parts of the pipelines properly, see Addition 1 for the details. For the purpose of systematic and simplified work, you may prepare only first elements and for other pipeline parts use ready copies of these already prepared and placed elements.
It is not necessary to rotate these widgets as this may cause visual contradiction with other elements of this category, due to the specific of gradient filling. That is why all four element orientations are provided without the need for rotation.

These widgets can be used by the developer to create mnemonic schemes with the pipelines. By rotating and mirroring these widgets, you can get all the combinations you want, based solely on the primitive "Elementary Figures". By scaling, you can set the desired geometric dimensions relative to the overall dimensions of the pipe network. To use it you need to add selected ones to a mnemonic scheme, systematically adjust for the geometry and properly visually connect into or between the pipeline elements, see Addition 1 for the details. For the purpose of systematic and simplified work, you may prepare only first elements and for other pipeline parts use ready copies of these already prepared and placed elements.

3 Addition 1: Adjustment and fitting of elements, construction of complete pipelines
This library contains and is intended for the construction of integral pipelines of arbitrary configuration of its individual elements, which need to be visually connected to each other so that there are no obvious displacements along the common axis and the intervals between the connection of visual elements, especially for primary elements of the pipeline and with the ability to have an equally perfect appearance across a wide range of scales, ideally at all.
The need for wide-scale mnemonic schemes is relevant because of the unified construction of the mnemonic schemes in the resolution 900x600 and the ability to perform them on large resolutions of modern displays, when the zoom factor can now reach 10.
Therefore, all imperfections of the manual fitting there will immediately pop up and spoil the picture, since it is difficult to do without special means and on the initial screen of development it is impossible to see them.
Accordingly, the following rules are recommended for fitting the elements to obtain the desired result:
- Aligning elements by axis should be performed by centering, since they are all unified in size 100x100 and at the condition of providing their systematic arrangement on the mnemonic scheme on the same scale, typically 0.2.
- Perfect fit is more difficult because there is currently no tool to draw one element to the nearest border of another, and it is possible only at a separate calculation of the coordinates. Therefore, it is recommended to partially overlap one element to another, at 100% development scale, after the previous rule and according to the algorithm:
- to pull up the second element to the first, in one pixel step (holding down Shift) until the visual gap disappears, that is, the maximum possible distance remaining there will be 1 pixel;
- compensate this remain by another step of 1 pixel.
-
When developing at a scale other than 100%, say 150%, we get a maximum compensation of 1*(150/100)=1.5, ie the compensation steps must be the larger whole (ceil) — 2.
-
The latter rule is obviously not perfect and for a translucent fill color will lead to another defect namely the unevenness of the final color in the connection locations, which can however be used for visual inspection in the design of opaque schemes. But if you still need such an opportunity without the need for separate calculations, then order-motivate the developers to create a tool for reaching out!
Applying these rules can be quite simple to get the result in the figure:
