
value[1] Datetime: The current date and time stored in the M-Bus device.

value[2] m³: The meter reading at the last reference day. Reference days are configured by the
installation tool for the device and define a fixed date or recurring pattern when data will be
recorded.

value[3] Date: The last reference day.

value[4] Date: The next reference day.

value[5] l/h: The current flow of water.

value[6] m³: The meter reading at the end of the month.

value[7] Date: The date of last months reading.
Creating an M-Bus Type Translation
After you have read the data specification for the M-Bus device and determined how to interpret the
various elements in the M-Bus data point, you can use a type translation to extract each element and
convert it to a L
ON W ORKS data point.
The Type Translator includes three pre-defined rule-based type translations for converting water,
power, and thermal measurements generated by M-Bus devices. The names of these translations
consist of the manufacturer and model number of actual devices for which they were designed.

MBS_HYDROMETER_SCAMPY_1. Converts the current meter reading (the [0] element) and
the current water flow (the [5] element) of the UCPT_MBS8 input data point of an M-Bus water
meter to SNVT_vol_f and SNVT_flow_f output data points.

MBS_EMH_EIZ_EDWS_7390. Converts the total watts per hour (the [2] element) and total
watts (the [3] element) of an UCPT_MBS7 input data point of an M-Bus power meter to
SNVT_elec_kwh_l and SNVT_power_f output data points.

MBS_ACTARIS_CF50. Converts the total energy (the [0] element), current energy (the [2]
element), flow temperature (the [4] element), return temperature (the [5] element), and
temperature differential (the [6] element)of an UCPT_MBS9 input data point of an M-Bus thermal
meter to SNVT_elec_kwh_l , SNVT_power_f, SNVT_temp_f, SNVT_temp_f, and
SNVT_temp_diff_p output data points.
You can either use one of these pre-defined M-Bus type translations or create your own custom M-Bus
type translation using one of these as a starting point. To use one of these three pre-defined rules,
select one from the list below the Rule icon.
