1 Primitives of the widgets

Any newly created widget is based on one of several primitives — end element of the visualization, by installing of the kinship as directly to the primitive, as well as through the several intermediate user widgets. Each of the primitives contains a mechanism of the data model. An instance of the widget stores the properties values of the primitive own configuration.

The tasks of the visualization interface include support and work with the data model of the widgets primitives. The widgets primitives should be thoroughly worked out and unified, in order to capture as many opportunities as possible in a smaller number of poorly linked, with the purpose, primitives.

Table. Library of the primitives of the widgets — basic elements of the visualization.

Table. The common set of properties/attributes in the widget

Identifier Name Number Value
id Identifier - Identifier of the element. The attribute is read-only, designed to provide information on the ID of the element.
path Path - Path to the widget. The attribute is read-only and designed to provide full information about the element location.
parent Parent - Path to the parent widget. The attribute is read-only and designed to provide information about the ancestor location which the widget is inherited from.
owner Owner - The widget owner and group in the view "{owner}:{group[,group1,groupN]}", by default the "root:UI".
perm Permission -

Where "user", "group" and "other" is:

  • "__" — no access;
  • "R_" — read-only;
  • "RW" — read and write.

By default the 01000 — inheritance.

root Root 1 Identifier of the widget-primitive (basic element) which underlies the widget visualization shape.
name Name - Name of the element. Accessible to modification the element name.
dscr Description - Description of the element. Text field of the brief description.
en Enabled 5 The state "Enabled" of the element. Disabled element is not shown in the execution mode.
active Active 6 The state "Active" of the element. Active element may receive focus in the execution mode, and thus receive keyboard and other events with their subsequent processing.
geomX Geometry: x 7 Geometry, coordinate 'x' of the element position.
geomY Geometry: y 8 Geometry, coordinate 'y' of the element position.
geomW Geometry: width 9 Geometry, the width of the element.

tipTool Tip: tool 15 Text of a brief help or tip on this element. Realized usually as a tool tip, while keeping your mouse cursor over the element.
tipStatus Tip: status 16

Text information on the status of the element or the guide to action over the element. Implemented usually in the form of a message in the status bar while keeping your mouse cursor over the element.

* Modification the attribute from session of the root page will record the message in the status bar of the visualization window of the session.
contextMenu Context menu 17

Context menu in the strings list view: "{ItName}:{Signal}".
Where:

  • "ItName" — name of the item;
  • "Signal" — name of the signal, which forming at the selecting: "usr_{Signal}".
evProc Events processing -

Attribute for storing of the script of the events processing for direct control of the user interface. Script is a list of commands to the visualization interface, generated at the event receipt (attribute event). Direct events processing to manage pages, in the view: "{event}:{evSrc}:{com}:{prm}". Where:

  • "event" — waiting event;
  • "evSrc" — event source;
  • "com" — command of the session: open, next, prev;
  • "prm" — command parameter, where used:
    • pg_so — direct name of the desired page, with the prefix;
    • 1 — name of the new page in a general way, without a prefix;
    • * — the page is taken from the previous page name;
    • $ — indicates the place relative to which the page opens.

Examples:

  • ws_BtPress:/prev:prev:/pg_so/*/*/$
  • ws_BtPress:/next:next:/pg_so/*/*/$
  • ws_BtPress:/go_mn:open:/pg_so/*/mn/*
  • ws_BtPress:/go_graph:open:/pg_so/*/ggraph
Additional attributes for items, placed into the project in the role of a page.
pgOpen Page: opened -

Sign "The page is opened".

* Modification from the session provides an immediate opening/closing the page, but for the pages type "Link" you must prefer of the user API function uiCmd() using to the pages managing.
pgNoOpenProc Page: process not opened - Sign "Execute the page, even if it is closed".
pgOpenSrc Page: source of the opening 3

Full address of the page which has opened this one.

* Writing/clearing the widget address, of the opening initiation, performs an immediate opening/closing the page. In the case of writing the address and on certain conditions, the dynamic linking of the current widget to the initiator performs. But for the pages type "Link" you must prefer of the user API function uiCmd() using to the pages managing.
pgGrp Page: group 4 Group of the pages. EMPTY and the "main" group is meant of using this page as the Root-main page, so such ones will replace other Root-main pages; the "fl" group is meant of using in the "fly" windows which are suitable for multiple open and must not be traced for doubles; all other are meant for including to the containers-boxes or single opening, so they forced in checking for doubles when the last one will be opened and the previous ones be closed.
Additional attributes of the execution mode — by the session.
(Virtual attributes are not available in the widget procedure)
event Events - Special attribute of the collection of events of the widget in the list, which is divided by the new line. Access to the attribute is protected by a critical section in order to avoid loss of the events. The attribute is always available in the widget procedure.
load Load -1 Virtual command of the group data download.
focus Focus -2 Special attribute of the indicating the fact of receiving the focus by an active widget. Attribute of the widget and of the included widgets is available in the widgets procedures.
perm Permission -3 Virtual attribute of the rights of the active user to view and control the widget.
* — Special function of the widget attribute which executing in the project session at any user's modification.

The engine of the visualization environment provides activation of the visualizer specific attributes. The activation process performs at opening a session of the project and means for the project: creation of the specific attribute with the specified properties, at case it lack, and activation for tracing its modification by the engine of the visualization environment, like to the attributes of forming primitive's shapes. To direct specifying such attribute you can also use the prefix "vs_" to the attribute identifiers, what is mach faster and excludes of the activation stage. For the specific attributes list of the visualizer you can see the documentation of the proper visualizer.

1.1 Elementary graphical figure (ElFigure)

The primitive is the basis for drawing basic graphical shapes with their possible combinations in a single object. Taking in the account the wide range of various shapes, which must be maintained by the primitive, and at the same time the primitive must be simple enough for using and, if possible, for implementation, it was decided to limit the list of the basic figures used for the construction of the resulting graphics to these figures: line, arc, Bézier curve and fill of the enclosed spaces. Based at these basic figures, it is possible to construct derived figures by combining the basic. In the context of the primitive, there is a possibility to set the transparency of the color in the range [0...255], where '0' — complete transparency.

1.5 Element of constructing diagrams (Diagram)

This primitive targeted to construct various diagrams in the time, including graphs-trends showing ongoing process and the archive data. Following types of the diagrams are implemented:

  • "Graph-trend" — builds a graph of the parameter values in the time.
  • "Spectrum" — builds the frequency spectrum of the parameter values. Window of the data of the frequency spectrum is formed on the basis of the horizontally size of the widget, in pixels, and the available data of the parameters imposed on the grid of the horizontal size. Due to this, the minimum allocated frequency is determined by the value of the attribute "tSize" — "1/tSize", and the maximum one is determined by half-width of the graph in pixels multiplied by the minimum frequency "width/(2*tSize)".
  • "XY" — builds the two-dimensional graph of the parameters values, by pairs to one graphic, where paired by axis Y (0,2,4...) and unpaired by axis X (1,3,5...). Specified data time range is used in the received values of the parameters of the X and Y axis, with the subsequent imaging.

For all the diagram types possible to set, as the data source:

  • parameter of the subsystem "DAQ";
  • value archive;
  • direct data block from the user.

The tracking mode is supported for current values and values from the archive, and it is possible to construct graphs of parameters that do not have a value archive by accumulating the current values in the buffer of the diagram and only at the moment of active display of this diagram.

Process of access to archival data is optimized by introducing an intermediate buffer of displaying, as well as the packaging of data traffic upon request, by bringing the data to a quality sufficient to display.

Attributes of the enabled archival mode
aCur Archive: cursor: current - Position of the current document in the archive. Record of the value <0 produces the archiving of this document.
vCur Archive: cursor: view -

Current visual document of the archive. Writing a value of:

  • -1 — selecting the next document;
  • -2 — selecting the previous document.
aDoc Archive: current document - Current archive document in XHTML, starts from the tag "body".
aSize Archive: size - Real size of the archive document.

Features of the primitive "Document":

  • Flexible formation of document structure based on HyperText Markup Language, which provides support for a wide range of features in the documents formatting.
  • Formation of the documents at a command or a schedule, which necessary for creation of reports to the archive and then reviewing the archive.
  • Formation of the documents in real time, to provide them completely dynamically and on the basis of archives at the specified time.
  • Using the widget attributes for transmission to the document of values and addresses to the archives, which allows you to use the document widget as a template when generating reports with other input data.

The basis of any document is the XHTML template. The XHTML-template is the tag "body" of the WEB-page which contains the document's static in the standard XHTML 1.0 and elements of the executable instructions in the user programming language of OpenSCADA in the view <?dp {procedure} ?>. The resulting document is formed by the procedures execution and insertion of their result into the document.

The source for values of the executable instructions are the widget attributes of the primitive, as well as all the mechanisms of the user programming language OpenSCADA. Attributes may be added by the user and they can be linked to the actual attributes or parameters or they can be autonomous, values of which will be formed in the widget procedure. In the case of linked attributes the values can be extracted from the archive-history.

The figure shows the structure of the widget of the primitive "Document". According to this structure, "Document" contains: XHTML template, results documents and data processing procedure. Data source of the procedure and output documents is attributes of the widget.

Figure. Block diagram of the primitive "Document".

Working in two modes is provided: "Dynamic" and "Archive". Difference between archive mode is the availability of the archive of the specified depth and attributes which allow you to control the process of archiving and viewing of the document in the archive.

Generation of the document is always performed at the time of setting of the attribute time relative to the earlier set begin time of the document in the attribute bTime. With the archive turned off the resulting document is placed directly in the attribute doc. When the archive is turned on the resulting document is placed in the cell under the cursor, the attribute aCur, as well as in doc if value of the archive cursor aCur and the visualized document cursor vCur match. Attributes of the archival cursors provide several command values:

  • "aCur < 0" — moves the archiver cursor to the following position, thereby leaving the previous document in the archive and clearing the document under the cursor, at short the circle archive.
  • "vCur == -1" — selecting the next document to be displayed, the selected document is copied to the attribute doc.
  • "vCur == -2" — selecting the previous document to be displayed, the selected document is copied to the attribute doc.

As mentioned above, the dynamics of the document template is determined by inserts of executable instructions of the view "<?dp {procedure} ?>". The procedures may use the same attributes of the widget and functions of the user programming interface of OpenSCADA. In addition to widget attributes, special attributes are reserved, see the table.

Table 3.8.7.a. Special and reserved elements of the template.
