Select Box
After selecting Add Box..., a Selection Diagram for the specified I/O module appears, according to the selected fieldbus system (in this case Beckhoff Lightbus).
The tree view of the Selection Diagram displays all possible I/O modules (see also Technical Reference). These are sometimes listed in order of manufacturer to simplify viewing.
The Profibus and DeviceNet fieldbus systems support I/O configuration with description/configuration files supplied with the systems (or by each manufacturer). Adding these types of GSD/GSE and/or EDS boxes is described under Adding GSE and EDS Boxes.
Type
Shows the possible I/O modules. These can be compact or modular I/O devices, and drives with digital interface (like the AX2000 drive shown in the example).
Name
The identifier for the selected module can be edited here.
Ok
Confirms a module selection and closes the dialogue. Alternatively, double click to achieve the same result.
Cancel
Closes the dialogue without adding a module to the configuration.
