Image 8-8 Data transfer LOGO! to KNX: Dimming - DPT 1.001 and DPT 3.007
LOGO! data type
Set a 1-bit LOGO! data type as the preselection for the "Dimming" function:
● Digital input
● Digital flag
● 1-bit variable memory
KNX data type
Two communication objects are provided in the ETS:
● Switch - DPT 1.001 and
● Dimming - DPT 3.007
The configured binary variable can be used for 1-bit dimming. A distinction is made between
short and long setting:
Switch (short setting up to 500 ms) - DPT 1.001
With short setting, the value currently in the switched object (switch over) is inverted and
then sent. The on or off message frame is only generated when the binary value is reset (=
falling edge).
