FB_Rec_Teach_In_Ex
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.
In addition to the FB_Rec_Teach_In() function block, the system also checks whether it is an EEP telegram.
