FB_Rec_Teach_In
This function block indicates when a learn button is pressed on an EnOcean device. If the bLearnType flag is set, then further information can be read out from the EnOcean device. This function must be provided by the EnOcean device. (So far, it is only supported by very few EnOcean devices).
