|Data extension identifier||System text (without spaces and diacritics). It is used for unambiguous identification of data extension in data item (e.g. for Extension property).|
The default value is "trend".
|Target object (PmaTrendGroup)||Path to the target object of appropriate type, in which the data item must be registered. The object can also be selected by the button on the right.This selection allows to modify the trend type, saving period and another parameters defined in the PmaTrendGroup object. |
Macro expression can be used for input, the result must be a NON-LOCALIZED path to Pma object (it is evaluated after starting the application).
|Trend identifier||Trend identifier and variable (column) name in the trend database table. |
Caution! The variable name must comply with the limitation of corresponding database table column name (see the "Storage type" configurator).
Macro expression can be used for input, the result must be a NON-LOCALIZED SYSTEM text (it is evaluated after starting the application).This configurator must not contain an empty string.
|name for displaying||Text that can be shown as the name of the item in the trend viewer. |
This configurator sets the initial value of the property DisplayName.
|Order||Specifies the order (placement) of variable (column) in the trend database table. The order is defined upwardly according to order value (weight). The order value is represented by a decimal number (>= 0), allowing to insert new variable between any two other variables. The value does not represent the specific variable index in the table, but more likely it represents a weight used for evaluating the order.|
|Minimum||Low limit of the variable (minimum). |
This configurator sets the initial value of the property Min.
|Maximum||High limit of the variable (maximum). |
This configurator sets the initial value of the property Max.
|Dead band||Value insensitivity range. It is valid only if the optimalized value storage is enabled (see Enable saving of variables on change).|
|Unit||Physical unit of the variable (for example "kWh"). |
This configurator sets the initial value of the property Unit.
|Color||Color of the variable for displaying in the trend viewer. |
This configurator sets the initial value of the property Color.
|Additional parameters||Additional parameters for saving the trend variable. Allow to define the database data type or table column name.|
dbdt (optional) - Database column data type. For specific database data types see the "Storage type" configurator, for example "dbdt:NUMERIC(12,4);".
|Value type||Method for obtaining value for evaluation (testing):|
2 - defined bit - negated - A negated value of defined bit is used.
pVal: The value of PmVar.Value variable for simple usage in the expression.
pDE: Reference to data extension object (for obtaining other values from data extension or from variable).
pVar: Reference to PmVar object of the data extension.
If all items for the PmaTrendGroup object are of the "Data extension" type, then the "PmaTrendGroup > Data" page may remain empty. If there are both types of items present in the PmaTrendGroup object, then in the database table the PmVar type items will be entered first followed by the "Data extension" items.
