Note
:strong:Configuration \ with ControlBuilderPlus (ABB solution)
The physical layers are selectable as submodules in PROFINETâ configuration (parameter Physical Layer not visible and fixed with the correct value). Certain parameters are not visible if a certain physical layer is selected. This concept of parameterization provides a better usability than configuring via GSDML (see below).
Note
:strong:Configuration \ via GSDML (use by non-ABB PROFINETâ configuration tool)
All parameters are visible independent of the configured physical layer (via parameter Physical Layer). The user must take precautions for each parameter since certain parameter values are invalid for certain physical layers. Nevertheless, the CI504-PNIO performs a parameter check depending on the configured physical layer and generates a diagnosis message (parameter error) in the case of error.
