FB_Rec_Teach_In
This function block indicates when a Learn button is pressed on an EnOcean® device. If the flag bLearnType is set, further information about the EnOcean® device can be read. This function must be provided by the EnOcean® device. So far, however, it is only supported by very few EnOcean® devices.
