EIB Delta-Meter
Electricity Meters
Meter reading [EIS 11; 32 bit counter]: The measured energy consumption
values or meter readings are transferred via the 4 byte output communication
object "Meter reading". The application software "Tariff meter/1.1" has five
meter reading objects altogether, one for each of the four tariffs and one for
the total. The application software "Combination meter/1.1" has one object for
the active energy and one for the reactive energy. The transmitted data
correspond to the values that are displayed on the LCD display.
The sending behaviour of these objects is defined in the parameter window
"Meter readings".
Object type Measuring range
4-Byte 0 .. 999 999 990
Instantaneous power (active/reactive) [EIS 10; 16 bit counter]: The 2 byte
output communication object "Instantaneous power" is used to transfer the
instantaneous power or energy consumption. The sending behaviour of
these objects is defined in the parameter window "Instantaneous power".
Object type Measuring range
2-Byte 0 .. 65534 (65535 = Überlast)
The application software "Combination meter/1.1" has separate communication
objects for the instantaneous active power and the instantaneous reactive
power. In addition, it is possible to transfer the reactive power as:
a 2 byte object [EIS 10; 16 bit counter] (see above) with a separate
"Reactive power type" [EIS 1; switching] object in order to transfer the type
of reactive power.
Telegram value "0": inductive reactive power
Telegram value "1": capacitive reactive power
or as a 4 byte object with sign [EIS 11; 32 bit counter].
Object type Measuring range

If the actual instantaneous power lies above 65534 W (var), the value 65535

Request meter reading [EIS 1; switching]: The read request for the current
meter readings of the EIB Delta-Meter is transferred to the meter via the 1 bit
input communication object "Request meter reading". Once a request signal
telegram with the value "1" has been received, the meter reading is stored
and sent on the bus once the transmission delay T
This sending behaviour is defined in the parameter window "Meter readings".
The communication object is only visible if the option "Send on request" is
selected.
Telegram value "1": Send meter reading
"0": No function
Switch tariff [EIS 14; 8 bit counter]: The 1 byte input communication object
"Switch tariff" enables the control of four different tariffs of an EIB Delta-Meter
tariff meter via the ABB i-bus
or 4), the meter switches to the required tariff. Once the transmission delay T
has elapsed (if selected), the current data of the old and new tariffs as well as
the total of all the tariffs at the time of the change are sent on the bus.
