Introduction

The "QTCfg" module provides the configurator of the OpenSCADA system. Configurator is based on multi-platform library of the graphical user interface (GUI) of the firm TrollTech Ч Qt (http://www.trolltech.com/qt).


At the core if the module lies the management interface language of the OpenSCADA system, and thus provides a uniform configuration interface. Update of the module may be required only in the case of updating the specification of the language of the management interface. To request a page context used the group request management interface that allows you to optimize time, for remote access to high latency and slow communication channels.


Lets examine the working window of the configurator in Fig. 1.

Operating window of the configurator consists of the following parts:
1 Menu Ч contains a drop-down configurator menu.
2 Toolbar Ч contains buttons of quickly control.
3 Navigator Ч is intended for direct navigation of the control tree.

3.1 Text enter field for elements search into current branch of tree.

4 Status line Ч indicating the status of the configurator.

4.1 Indicator/choice of the user Ч displays the current user. By double-clicking the user selection dialog opens. As well as an indicator of changes in configuration.

5 Workplace field Ч it is divided into parts:

5.1 Node name Ч contains the name of the current node.
5.2 Tabulator of the working areas Ч the root page (management areas) of the node are placed into the tabulator. The management areas of the following levels are placed on the information panel.

Menu of the configurator contains the following items:


The toolbar contains the following management buttons (from left to right):


In the navigation tree the context menu of following contents is supported:


The control tools are divided into basic, commands, lists, tables and images. All items are displayed in the sequence strictly appropriate to their location in the description of language of management interface.

1. Configuration

To adjust your own behavior in the not obvious situations module provides the ability to customize individual settings through the management interface of the OpenSCADA (Fig. 2). These parameters are:

2. Basic elements

Into the number of the basic elements are included: information elements, the field to input values, the elements of combo box, flags, text fields. In the case of absence of an element name, the basic element connects to the previous basic element. Examples of basic elements with the connection is shown in Fig.3.


For input elements that do not mean instant change and may be edited for a long time before a final conclusion, a confirmation mechanism is foretold. This mechanism eliminates the delay when editing, especially in the case of the configuration of remote stations, and to make changes on the confirmation. To elements of input with confirmation include: input line fields of text or numeric values and text fields. Confirmation is made by pressing the button that appears next to the input field after the start of editing.


Input and display text field supports the ability to change the height by setting the bottom edge of the widget and dragging it. In addition the text box supports syntax highlighting, rules which are transmitted in the form of regular expressions from the management interface.

3. Commands

Commands are the elements for the transfer of the certain instructions of the action to the node and for the organization of the links on the page. Commands may contain parameters. The parameters are formed from the basic elements. Example of the commands with the parameters is shown in Fig.4.

4. Lists

Lists contain a group of basic elements of the same type. Operations under the elements are accessible via the context menu of the list. Through the elements of the list can be performed the moving operations to other pages. The transition is implemented by double-clicking of the mouse on an element of the list. Lists can be indexed. An example of the list is shown in Fig. 5.

5. Tables

The tables contain values of the basic elements. Type of the basic element is an individual for each column. Example of the table is given in Fig. 6. Operations on the structure of the table for editable tables are accessible through the context menu. Editing of the table is done by double-clicking on the desired cell.


Tables support the ability to change the height by setting the bottom edge of the widget and dragging it.
