Layers and Interaction Windows
Control modules in layer 2
When a control module contains other modules, so called sub modules, it is
recommended that they are placed in layer 2. Zooming in on the module will reveal
the sub-modules, which gives a good overview and also fast access to the modules.
There are mainly three categories of sub-modules which are placed in layer two:
1.
Interaction windows - used for operator interaction with the object. In this way
the user gets fast access and overview of the windows belonging to the object.
2.
Internal code structure - some internal control modules may be related to the
connections of a module. By placing the control module close to its
corresponding connection the user/developer gets a fast access to the correct
module.
3.
Applications - used for structuring application and/or reuse of application
solutions. This gives a good overview of any applications residing inside the
object, for example a control loop or a section of a process.
It is recommended that control modules representing interaction windows are
visible in layer 2 of a control module. To make them visible, either create them in
the CMD or set the property Visibility in Graphics to Visible on the object in the
project explorer structure.
