2-Wire Energy Monitor

Other modules such as EMM.120... 630 do not have
SerialNr, but only Modbus addresses (range 1-247).
However, only serialnrs canbe used in the
projectammation.
That's why we're going to make a
fictitious
serial
number
for these
modules
ourselves.
Most
modbusmodules only need one channel, except for
the more complex modules such as the EMM.630 or
calorie meters. Those modules have 3 or more
channels (e.g. 3 phases) .
The maximum is 8
channels per module. (08xxxxxx)
The first two digits of the serial number shall
determine the number of outputs/entries:
1.
'01' are for single-rigid meters
2.
'02' are for single-rigid meters, which
measures in both directions (import-export)
3.
'03' are for three-legged meters
You can choose the following 5 digits yourself, but
make sure the serial number remains 'unique'!
Examples for the EMMxxx energy modbus meters
series:
1.
Enkelfasige (enkel import): EMM120

EMM220 :

The limit of the number of log channels is 64 and the
limit of the number of modules is 32.
The first serial number we are going to enter in the
field
'SerialNr'.
In the 'Module
Name'
field, one can
enter a name related to the module. (e.g. distribution
cabinet garage... thermostat..) When we press
'NEW'
now, the typed serial no. is put in the 'list
box'.
On the right side of the picture, a module will appear
with a number of channels according to our serial
number
(e.g. 01E00001 = 1 channel. )
1.
CH
: stands for 'CHANNEL' and is automatically
generated by the web server. This channel No
will later serve to make the link between log
channel and (modbus) address. (see below).
2.
MODE:
(Counter, Thermostat, AirQ....) is
automatically dialed
3.
ADDR:
Each channel must have a UNIQUE
ADDRESS
in the range 1-247. Therefore, no
channel may have the same address. Start
from 1 and number so that each meeting
entrance has a unique address. The simplest
is for
'ADDR'
to fill in the
same value
as the
channel number
'CH'.
When we have
modules without a serial number (series
EMMxxxx) we have to program these
addresses on these modules via the existing
display.
(How to change the address on the
module is described in the manual of the
module itself.)
4.
S
UBAD
: for modules with multiple log
channels such as 3-fazen meters and calorie
meters there is always only 1 modbus
address, but with the subaddress you can log
different data:
For the EMMxxxx series:
1.
serienr 01Exxxx : subadd = 0
2.
series no 02Exxxx: both channels
SAME
MODBUS
ADDRESS,
subadres 0 (import) and
subadres 1 (export)
3.
series no 03Exxxx: all 3 channels
SAME
MODBUS
ADDRESS
, subad = 0

1 - 2
4.
PARA3: PARA6
: are specifically explained in
the manual of the modules. Nothing needs to
be filled in for the EMMxxx.
