Working with basic requirements

Introduction
With the help of the "Basic requirement" option, the minimum requirements on the control
module to be assigned are given an abstract description; e.g. the required commands or
feedback via the status.
Control modules assigned to an equipment module (type) are marked as so-called basic
requirements if they describe only the requirement for one control module and are not to be
included implicitly in the copied quantity in the course of instancing. If you define control module
assignment, use a control module basic requirement or a specific control module as part of the
equipment module type.
Requirement
● The "Type configurator" plugin is open.
See also Chapter Opening the Type configurator plugin (Page 59).
● An equipment module (type) is created.
See also Chapter Creating an equipment module (type) (Page 41).
● At least one control module type is created.
See also Chapter Creating a control module type (Page 25).
Procedure
1. Create a control module assignment below the equipment module (type) in the "Type
structure" column.
2. Drag the desired control module types using the drag&drop feature from the "Type library"
column to the equipment module in the "Type structure" column.
3. Enable the option "Basic requirement" in the "Type attributes" column of the lower-level
control module types.
4. Using the drag&drop feature, drag the control module basic requirement to the control
module assignment.
You may assign the basic requirement as often as required to different control module
assignments within an equipment module type.
