Logic functions
The KNX room thermostat EK-EQ2-TP allows to use some useful logic functions (AND, OR, NOT and
exclusive OR) in order to implement complex functions in the building automation system.
You can configure:
8 channels of logical functions
4 inputs for each channel
Each object value, if desired, can be individually inverted by inserting a NOT logic operator.
For each channel, a parameter
Delay after bus voltage recovery
is available: this parameter represents the
time interval between the bus voltage recovery and the first reading of the input communication objects for
evaluating the logic functions.
In case of uncorrect connection of the input communication object or electrical trouble on bus
resulting in a failed input reading request, the logic output of the corresponding channel can be
calculated by setting the input values to default.
The communicaton function representing the logic function output is sent on the bus on event of change;
alternatively, a cyclic sending can be set.
7.13.1
Parameters and communication objects
The following condition has to be true: General
Logic functions = enabled.
Parameter name
Conditions
Values
Logic function
disabled
/ enabled
Logic operation
Logic function = enabled
OR
/ AND / XOR
XOR (eXclusive OR)
Delay after bus voltage recovery
00:00:04.000 hh:mm:ss.fff
[range 00:00:00.000
… 00:10:55.350]
Time interval between the bus voltage recovery and the first reading of the input
communication objects for evaluating the logic functions
Output cyclic transmission delay
no sending
[other value in range
30 s … 120 min]
No sending means that the output state of the logic function is updated on the bus
only on change. Different values imply cyclic sending on the bus of the output state.
Logic object x
disabled
/ enabled
Negated
Logic object x = enabled
no
/ yes
Negando lo stato logico dell’ingresso corrispondente, è possibile realizzare logiche
combinatorie articolate. Esempio: Output=(NOT(Oggetto logico 1) OR Oggetto
logico 2).
Read at startup
Logic object x = enabled
