9 Logic functions
9.1.1 Using logic functions
Complex switching sequences can be realised in the Com-
fort Panel using so-called
Logic functions
which can be
configured in the graphical logic editor of IP Project.
Logic functions
essentially consist of logic modules that
are organised into a logic network. Input and output modu-
les are interfaces of the logic network to a KNX or IP-
based network (see section
Input and output modules ).
Notes:

The logic functions are event-controlled. For
every arrival of a telegram at an input module,
all logic modules affected by this event are re-
calculated.

If the recalculation of a logic function is trigge-
red by a telegram input, the input modules are
allocated with the value of the last telegram to
come in.

Time-controlled logic functions automatically
carry out a recalculation after expiry of the
specified time.

Within a logic network, only the five data ty-
pes
Boolean
,
Number
,
Date
,
Time
, as well as
String
are used instead of the KNX data types.

The logic engine of the Comfort Panel is a ca-
pable and complex tool for a smart and effi-
cient realization of logic networks. However, it
must be kept in mind that a logic network is
triggered on each arriving telegram. That is,
the logic network is re-calculated on each new
telegram and new output telegrams are sent.
When used in an inappropriate way this may
lead to an overload of the KNX bus!
