Image 8-11 Data transfer LOGO! to KNX: Solar protection
LOGO! data type
Set a 1-bit LOGO! data type as the preselection for the function "1-bit shutter/blind / solar
protection":
● Digital input
● Digital flag
● 1-bit variable memory
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.
The configured binary variable can be used for 1-bit solar protection control. A distinction is
made between short and long setting:
Solar protection up / down (long setting 500 ms or more) - DPT 1.008
In the case of long setting, and depending on the last direction of movement saved in the
object "Solar protection up / down", this is inverted and the solar protection is driven up or
down until the respective end position has been reached and the drive is switched off by the
limit switch. If a stop command is received before an end position has been reached with
activation of the limit switch, the movement is terminated immediately, the reached position
is retained, and the last direction of movement is saved.
