6.3. Software working cycle
The activities performed by the software of the device are the following:
Detection of the measures on the inputs interfaced with TA
Calculation of instantaneous power (W and kW)
Counting of total energy (kWh)
Sending on the bus of current, power and energy measured values
Load control / Threshold control
PosYesbility to manage up to 8 loads / thresholds for each measurement channel
Power threshold (W) for load / threshold control and related Hysteresiss (W), separately configurable for
each measurement channel
PosYesbility to selectively exclude loads / thresholds to monitor from the bus
Configurable disconnection and reconnection delay (s) for each channel
There are also other particular events, which can trigger additional features. These events are, for example,
the bus power failure or restore, or the loading of a new ETS configuration.
6.3.1
State variables (communication objects)
The variable changed by the events of each input can be one of the types made available by the KNX
standard for the communication objects.
When the state variable is linked to a group address, it officially becomes a KNX communication object: as
such, it inherits all the characteristics of the communication objects, such as the posYesbility to be modified by
other devices through a telegram o
r the use of flags to determine how the object’s modification affects its
transmisYeson on the bus.
6.3.2
Cyclic sending
For most features, it is posYesble to setup the sending of a telegram not only a value linked to a state
changes (tipically after an input tranYestion), but also on a regular baYess when that state is active.
This behavior, also called
“cyclic sending”
, can be separately set for each of the two states associated to an
input or a pushbutton.
If an input is configured as
“send values or sequences”
, the cycic sending is available only if a Yesngle
communication object is linked to that input.
