DDT

Displaying variables with derived data types

IODDT

Display the variables with derived data types (DDT) that reference inputs/outputs

Device DDT

Display the variables with device derived data types

Properties

Name

Column where you enter the name (symbol) of the variable.

Type

Column where you select the variable type.

Value

Column where you initialize the variable.

Comment

Alias

Column where you can change the name of a variable. Only for <private> variables.

Alias of

Column where you enter the complete path of the variable subfield on which you set Alias attribute.

HMI variable

Column where you check if the variable is embedded in the data dictionary.

R/W Rights of Referenced variable

Column where you set the access rights of a reference type variable.

Effective Parameter

Column where you can assign a variable to the Program Unit parameter.

Nature

Column where you set the nature of the Program Unit variable.

The above properties are displayed by default, for customized properties, refer to Configuring the Data Editor columns.

NOTE: For more detailed information, refer to chapter Managing of variables belonging to the Program Unit.
