LonWorks meters
M-Bus and standard meters
Inputs or Outputs
The meter is available with various input and output as
options. The input can be used as an alarm or as a pulse
counter, e.g., for a water meter. The output can be used
as ON and OFF function, for example to switch off the
current by remote control.
The inputs/outputs are of opto-switch type and are gal-
vanic isolated from other electronics parts in the meter.
There are two input/output voltage variants; high and
low, (see technical data). Both variants are for AC/DC
voltage and are of polarity independent.
LonWorks Protocol
*)
The software is compatible with Lon Mark 3.2 and uses the
LonMark-proleUtilityDataLogger1.0.Adescriptionofnetwork
variables can be found noted in the DELTAplus/DELTAmax User’s
Manual.
Technical information (LonWorks)
*)
Operating and display elements:
Service pin and LED.
Bus interface: FTT-10A.
Communication rate: 78 kbps.
A software clock is implemented in the LonWorks interface to
enable readings from meter to be time-recorded.
The accuracy is ± 2 seconds per 24 hours.

M-Bus Protocol
The protocol is based on international standard IEC 60870.
The bus system is adapted for remote reading of energy
meters and works on the principle of master slave.
