Data - tab of the PmaData object

Data definition. The form of this tab is common to more Pma objects and hence the common description is stated in the description of the "PmaObject > Data" tab. Only configuration items of one variable are described here that are specific only for the the of this object.
Adding one or multiple new variables.
New variable - Opens the "Variable" configuration window, where new variable can be added.
Multiple new variables - Opens the "Multi items adding" configuration window, where any number of variables can be added.
Opens the "Variable" configuration window, where the marked variable can be edited.
Deletes the selected variables.
Moves the selected variable upwards in the list.
Moves the selected variable downwards in the list.
Opens window for text search.
Opens menu with additional options.
Export to XML file - see Data export to the XML text file. Various export types to the XML file are described in Import/Export in the editor of Pma objects.
Export to CSV file - see Data export to CSV text file
Import from XML file - see Data import from XML text file
Import from CSV file - see Data import from CSV text file
Import from the OPC server - This item is available only in the PmaOpcDaClientGroup object. Opens the "Viewing the OPC server address space" configuration window. On the selected level, it is possible to select multiple variables (by using the Ctrl, or Shift key), that are then added into this tab.
Sort - If sorts variables in the alphabetical order by the variable name. The order of variables is changed. Be careful in cases when variables are accessed not by the name but by index (order).
Data extensions - Opens the "List of data extensions" configuration window, displaying a list of all found data extensions (defined anywhere in the application), designed for this specific target object (see the "Target object" configurator in the corresponding data extension).
Configuration items variables - basic:
See Variable
NameName of the variable.

The maximum name length is 80 characters. This is a system name, so it must contain only alphanumeric and must not contain any diacritics, empty string, spaces and the first character must not be a number.

This configurator sets the initial value of the Name property.

Data typeData type of a variable. This data type is preserved in the variable and written values are converted into this data type.

The exception is the Variant data type - means that the variable preserves the last written value with its data type. Thus even an array can be stored in the variable (not allowed with the PmRtFree licence).

ValueHere you can define
- the value (expression), that will be assigned to the variable after starting the application, or
- the data binding to another value.

See Value property and see Data binding of the object PmVar.

Macro expression can be used for input (it is evaluated after starting the application).

RoundingIf checked, then the value in the variable will be rounded do defined accuracy on each writing.

It is functional only for numeric data types (Double, Single, Long, Short, Byte).

See also Pm.Round.

AccuracyPositive number indicating accuracy (number of decimal or whole places) to round the number to. For example:
0.01 = rounding to hundreths
0.1 = rounding to tenths
0.5 = rounding to five tenths
1 = rounding to whole numbers
10 = rounding to tens
25 = rounding to the closest multiple of 25
NoteNote for better orientation in the project, applicable through the script interface even in the running application.

This configurator sets the initial value of the Note property.

Macro expression can be used for input (it is evaluated after starting the application).

Configuration items variables - extended:
UnitPhysical unit of the variable (for example "kWh").

This configurator sets the initial value of the Unit property.

Macro expression can be used for input ($.text ..) (it is evaluated after starting the application).

Data extensionsAdditional Data extensions ca be configured here for alarms, trends, communication, etc.
The script access to the variable of the PmVar type on this tab is allowed by:
- by the Item method or
- by the Pm method with the usage of the #vars identifier

Pm8.02.00: ExtWriteAction: New data extension that defines when the events onItemBeforeWrite and onItemAfterWrite are triggered. Before, this has been set directly in the variable configurator, but this setting is now converted automatically into a data extension.
