DFANA-M
The left side of this window contains all parameters that
can be reported by DFANA-M module, while the middle
section of the window shows 5 groups of 4 addresses for a
total of 20 address; insert the desired measurements in the
chosen addresses selecting them in the list on the left side
and then press the little near to the position where
that measurement has to be inserted. To remove a mea-
surement from the channel press instead the little button -.
Additional options in this windows are the following:
Module Address:
it is the base address of DFANA-M mod-
ule to be configures or to be read.
Output Address:
enabling these parameter, the output ad-
dress of DFANA-M will be activated (the value of the output
address will be the same assigned to the base address).
Reset Energy:
reset the energy counters.
Reset Hour-meter:
reset the hour-meter.
Read:
transfer the current configuration of DFANA-M to the
configuration window.
Program:
transfer the configuration currently displayed in
the window to DFANA-M.
From File:
load from a file the settings of DFANA-M and
show them in the configuration window.
To File:
save on a file the settings shown in the configura-
tion window.
Default:
remove all measurements from the configuration
window (but not from DFANA-M).
=DFCC2:
fills the table with the same measurements of
DFCC2 module (for APPs iCasaMia and aCasaMia).
ID & Ver.:
ask to DFANA-M the ID code and the firmware
version.
Close:
quit the configuration panel.
As said before, the module will take a number of addresses
(1 to 20) depending on the current compilation of the table
shown in Figure 1.
If an empty table has been sent, then DFANA-M will take
for default a single address reporting a null measurement.
Concerning all the measurement of active, reactive and ap-
parent power, it is possible to choose from the list in the
configuration panel the measured units between W or KW
(or VAR/KVAR for reactive power, or VA/KVA for apparent
power) as in the following figure.
The choice must be done considering that the maximum
value which can be transferred on the bus is
✗
-32768 to 32767 for active and reactive power
✗
65535 for apparent power
If the installed powers do not override 32767 W (or Var),
then choose the 1st case, otherwise choose the 2nd one
(so that it is possible to report up to 32767 kW or kVar).
Idem for apparent power.
Concerning the active and reactive energy counters, each
value is made by 6 bytes, therefore 3 addresses are need-
ed for each counter (e.g. total active power 1-2, 3-4 and 5-
6). The total value of the energy in kWh (or kVarh for reac-
tive power) will be given by the formula:
65536x(Energy 1-2) + (Energy 3-4) + (Energy 5-6)/1000
For instance, suppose to have:
(Energy 1-2) = 35
(Energy 3-4) = 33897
(Energy 5-6) = 59
The energy value will be then:
65536x(35) + (33897) + (59)/1000 = 2.327.657,059 kW
that means more then 2327 MWh.
Mapping
The map of DFANA-M module can be displayed by BD-
Tools or DCP IDE as shown in the example of figure 2.
Like for all the group that can be displayed in the map, it is
possible to place labels near to each measurement for an
immediate visual identification.
