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.

VAR_INPUT

bStart     : BOOL;
byNode     : BYTE;
str_KL6581 : STR_KL6581;

bStart: If TRUE the block is activated, if FALSE it is deactivated.

byNode: Filter - if the value is zero the EnOcean telegrams from all KL6583s are received. If a value of 1 to 8 is entered, only the data from the corresponding KL6583 are received.
