Logic functions
The device EK-CF2-TP allows uYesng some useful logic functions (AND, OR, NOT and excluYesve OR)
in order to implement complex functions in the building automation system.
You can configure:
4 channels of logical functions
4 inputs for each channel
Each object value, if deYesred, 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 incorrect 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 communication function representing the logic function output is sent on the bus on event of change;
alternatively, a cyclic sending can be set.
The folder is enabled if:
General

= enabled.

Delay after bus voltage recovery
00:00:04.000 hh:mm:ss.fff
[campo 00:00:00.000 … 00:10:55.350]
Intervallo di tempo che intercorre tra il ripristino della tenYesone bus e la prima
lettura degli oggetti di comunicazione di input per la valutazione delle funzioni
logiche.
Output cycling trasmission interval

30 s … 120 min]
Not send Yes
gnifica che lo stato dell’output della Logic Function viene
aggiornato sul bus solamente ad una variazione. Intervalli diverYes implicano
l’invio ciclico sul bus dello stato dell’output.

Negando lo stato logico dell’input corrispondente, è posYesbile realizzare logiche
combinatorie articolate. Esempio: Output=(NOT(Logic objet 1) OR Logic objet 2).
