Object Properties Panel

The Object Properties Panel is by default shown on the right hand side of DataStudio. It shows all properties of the currently selected object. Objects can be selected in any panel in DataStudio and will be shown in the Object Properties Panel.

Alternatively, objects can be selected to be displayed in the Object Properties panel from the available DataStudio Displays by clicking the icon certificate view 32 icon, or selecting _Load in Property Panel from the context menu (shortcut: Ctrl+Shift+L).

This section describes the different sections of the panel.

Object Properties Panel
Figure 1. Object Properties Panel
The content of the Object Properties Panel heavily depends on the selected object type. This chapter describes the principles behind the object properties panel, not a description of each object type. For a detailed description of each object, please refer to the system documentation.

The header of the Object Properties panel always shows the object name, type (read only) and icon representation. In addition it contains a Refresh button which when pressed, will require all properties of the object currently shown in the panel from the Core server.

Object Properties Panel Header
Figure 2. Object Properties Panel Header

When the cursor is hovered over the header panel, a "+" appears beside the object icon. Clicking on this will open the advanced header properties.

Advanced header properties
Figure 3. Advanced header properties

The Advanced Header contains information about the object to give the user more detailed information about the history of the object and it’s current status. The table below explains the different fields.

The advanced header fields are populated by the system and are non-configurable by the user. They are accessible to read using the Lua Object Methods described in the Lua API section of the documentation.
Table 1. Advanced Header Fields
Header Field Description

Object ID

The unique Object ID used by the system internally to identify the object. This is particularly useful for Lua API and Web API developers.

Item Path

The path to the object in the respective Model Panel where it has been created. This is particularly useful Lua API and Web API developers.

Config Version

The Config version for the object indicates how many configuration changes the object has undergone since creation. The Config version incrementally rises each time object properties are changed and applied to the server.

Class Version

The class version of the object. The object is an instance of a particular class in system:inmation. The classes are

Created

The timestamp for the creation of the object. The following field contains the name of the profile that created the object.

Modified

The timestamp for the last modification of the object. The following field contains the name of the profile that made the modification.

State

The user state flag group (or bitmask) for the object describing the state of the object. A more detailed explanation of the user state flag group and the different section meanings can be found in the System Documentation).

Faceplate

The Faceplate section of the Object Properties panel is available only, when the selected object’s type has a dynamic value property. The type of Faceplate displayed depends on the type of inmation object selected. The Faceplate can be collapsed using the expand/collapse icon next to its section name. The available faceplate display options can be configured by clicking on the settings icon (icon settings32). The available display options will depend on the type of object selected, the types of faceplate display are described below.

Faceplate (for normal I/O Items)

Information Tabs

The different tabs on the Object Properties panel are only enabled when their function is active and their content applies to the currently selected object.

Object Properties Tabs
Figure 7. Object Properties Tabs

From left to right the following tabs are available:

  • Properties Tab Always enabled

  • Security Tab Enabled only when security profile was assigned to object

  • Object References Tab Enabled only when the selected object has a reference to or is referenced by some other object

  • Performance Counter Tab Enabled only when the selected object exposes information by performance counters

  • Instance Class Diagram Tab Always enabled

The functions and capabilities of these tabs are discussed in the following sections*.*

Properties Tab

This tab shows the properties of the object currently selected. Since different object types have different properties, the content of this tab changes depending on the object type. Hovering the mouse cursor over different elements in the tab will display a tooltip giving a detailed description of the element.

Object Properties Tab Displaying Tooltip
Figure 8. Object Properties Tab Displaying Tooltip

Changing one of the available properties (for example changing a limit value) will cause blue highlighting to appear around that property to indicate that it has been changed. To confirm the property change and update the information with the Core server press the Apply button at the bottom of the Object Properties panel.

Changing Properties - Blue Highlighting and Apply Button

Security profile removals are applied immediately

Object References Tab

If the currently selected object has references to other objects or is itself referenced by other objects, then the Object References tab will be enabled. The references to other objects will be displayed in the Object References table. Here the Name of the reference, the Type of reference and the Item Path of the object being referenced will be indicated in the respective columns.

Object Reference Table
Figure 14. Object Reference Table

In the Object References tab of the object that is being referenced this will appear as a Referenced By table, indicating the path of the referencing object.

Referenced By Table
Figure 15. Referenced By Table

Right-clicking on any of the references in the Object References table will display a context menu (shown below). From here the referenced object can be added to a display (Add item to…), or a value written to the reference object (Write Values, this action is possible if the user has write privileges over the referenced object). The reference can also be removed from the Object References table (Remove reference), renamed (Rename) or the referenced object can be found and highlight in the model tree panel (Find reference). The name and the path of the referenced object can also be copied to the clipboard (Copy name, Copy path).

Object References Context Menu

Performance Tab

If the currently selected object supports performance counters, this tab will be enabled and show a list of performance counter trends. Different inmation objects display different performance counters related to the object’s function. An object’s performance counters are grouped into different categories. To only view counters from a particular category, select from the drop down menu in the top left of the tab.

Performance Counter Tab
Figure 17. Performance Counter Tab

Each performance counter trend shows 60 seconds of performance data. For each performance counter, the name and the current value are displayed on the top left and the currently shown performance range and unit on the right.

The range of a performance counter trend changes automatically based on the currently shown values.

An object’s performance counters are grouped into different categories to make browsing easier. To only view counters from a particular category, select from the drop down menu in the top left of the tab.

Performance Counter Categories
Figure 18. Performance Counter Categories

The size of the performance counters in the object properties panel can be adjusted by selecting from the drop down menu in the middle, at the top of the tab.

Performance Counter Size
Figure 19. Performance Counter Size

The performance counters, by default, show the real-time performance data and update every second. However the display can be configured to show different time period aggregates by selecting from the drop-down menu on the right, at the top of the tab.

Performance Counter Time Period Settings
Figure 20. Performance Counter Time Period Settings

Selecting the 'Minute' configuration for example, shows the performance data aggregated every minute for the last 60 minutes. The Max, Min and Average values for each minute are shown in the trend part of the display (the blue trend line indicates the Count number of values at each minute time point). Hovering the mouse over the performance counter will also display this data for the chosen time point.

Performance Counter - Minute

Writing Values in the Object Properties Panel

Values can be written to I/O panel objects that have a dynamic value property (for example, I/O items, Data Holders, GenItems and Action Items) using the Faceplate in the Object Properties panel. To do this, first select the item in the I/O panel to display the Faceplate for the Item (including its current value) in the Object Properties panel.

Writing Values to Object - Faceplate
Figure 25. Writing Values to Object - Faceplate

Double-clicking anywhere within the Faceplate will open the Write Value dialog for the selected object.

Write Values Dialog Box
Figure 26. Write Values Dialog Box

The Write Value dialog opens and highlights the value field (containing the current item value). To write a new value to the object, chose the data type of the new value from the drop-down menu, then enter the new value into the Value field and click Write.

Write Values Dialog - Data Types
Figure 27. Write Values Dialog - Data Types
You cannot enter a null value in the Write Values dialog box, however null values can be written to objects using the SCI or Lua scripting. See the SCI and Lua scripting Chapters for more details about writing values to objects using these interfaces.

When entering a "String" data type, click on the Editor button to open the text editor box. Here you can enter larger blocks of text including line breaks (use Ctrl+Alt+Enter to enter carriage returns in the editor).

Write Values Dialog - Text Editor

Writing Array Values

Tick the "Array" checkbox to write values as an array. The Value field contains a guide for how array values should be entered, in square brackets, with each element of the array separated by a "|" character.

Write Values Dialog - Array
Figure 29. Write Values Dialog - Array

Null values can be written to elements in the array by either entering "|" twice (the null value being between the "|" characters) or by entering <null> as one of the elements.

Write Array Values - Entering null Values
Figure 30. Write Array Values - Entering null Values

An empty array of the type "[]" cannot be written as a value, however an array with two null elements can be written. For example "[|]" or [<null>|<null>].

Writing Null Values to an Array
Figure 31. Writing Null Values to an Array
Writing null values to arrays is only available in system:inmation v1.20 and above.

Generator Options

Clicking on the arrow next to "Generator" expands the options for generating a number using the sawtooth or sinewave functions. Press the "Play" arrow to start the generation then "Pause" to stop. Closing the Write Values dialog will then write that value to the object.

Write Values Dialog - Generator

Parameter - OPC Write Options

If writing to an I/O item in an OPC server namespace, the "Parameter" options allow you to choose the OPC Write options. Clicking the arrow next to "Parameter" expands the options.

Parameter Options in the Write Dialog
Figure 33. Parameter Options in the Write Dialog

Different OPC write modes can be selected and the delay between collecting writes configured. There is also the option to create an audit for the writes in the Session Log. Further information describing these configuration options in more detail can be found here.

JSON Viewer

Right-clicking on the faceplate will display the context menu from where you can copy the current value (shortcut Ctrl+C), copy the selected object’s property ID or display the current object value in the JSON viewer (shortcut Ctrl+Alt+J). The JSON viewer allows the user to visualize the structure of a JSON string as a tree structure, as displayed in the left hand panel of the Viewer window. The different fields of the JSON document can be selected here and viewed in the main window.

JSON Viewer
