There are 2 separate MOLEX PC-applications that could come in handy.
PFN TP CT (ProFiNet Teach Pendant Configuration Tool?): which is an application that looks and works exactly as the application that's running on a teach pendant. To use it, the PC needs to be connected by ethernet to the controller's CD38A or CD38B port.
PFN CT (ProFiNet Configuration Tool): which is for creating the libraries that's needed for the I/O-controller configuration. Downloads directly to the profinet card.
Both of them are covered (or at least mentioned) in the Profinet Manual for FANUC robots.
