8.6.4.4 Solar protection control (2 bits)
The two configured binary tags can be used together with long setting to raise or lower the
solar protection up to the respective end position or, together with short setting, to terminate
the movement or to adjust the slats by one step. It is possible to select which binary variable
is used to lower the solar protection or close the slats by one step or - in the opposite sense -
to raise the solar protection or open the slats by one step.
Image 8-13 Data transfer LOGO! to KNX: 2-bit solar protection
LOGO! data type
Set one of the following data types as the preselection for the function “Solar protection" with
2 bits:
● Digital inputs (2) for solar protection
● Digital flags (2) for solar protection
● 2-bit variable memory for solar protection
KNX data type
Two communication objects are provided in the ETS:
● Solar protection up / down - DPT 1.008 and
● Slats open / close - DPT 1.009.
A distinction is made between short and long setting:
Solar protection up / down (long setting 500 ms or more) - DPT 1.008
The “up / down" commands for raising or lowering the solar protection are sent via the group
address linked to this object. Which of the binary tags generates a raise or lower message
frame in the case of long setting can be set in the ETS.
