Dimming (2 Bits) With Stop Message Frame - Siemens LOGO! CMK2000 Operating Instructions Manual

Dimming (2 bits) with stop message frame

The two configured binary tags can be used together with short setting to switch on or off or,
together with long setting, to dim brighter or darker. You can select which binary variable is
to be used for switching off and dimming darker or for switching on and dimming brighter. In
the case of "Dimming (2 bits) with stop message frame", a dimming message frame
"Brighter" or "Darker" is sent as soon as long setting of a binary variable value is detected
(value 1), and a stop message frame upon resetting of the binary variable value (value 0 =
falling edge).

LOGO! data type
Set one of the following LOGO! data types as the preselection for "Dimming with stop
function":
● Digital inputs (2) for dimming
● Digital flags (2) for dimming
● Variable memories (2) for dimming
KNX data type
Two communication objects are provided in the ETS: Switch - DPT 1.001 and Dimming -
DPT 3.007
A distinction is made between short and long setting:
Switch (short setting up to 500 ms) - DPT 1.001
The switching message frames "On" and "Off" are sent via the group address linked to this
object. Which of the two binary variables is assigned to the on or off function in the case of
brief pressing of the key can be set in the ETS.
Dimming (long setting 500 ms or more) - DPT 3.007
The dimming message frames are sent via the group address linked to this object. Which of
the binary variables generates brighter or darker dimming in the case of long pressing of the
key can be set in the ETS.
