Issue
Addressing issues with M-Bus metering application because it is unclear what Storage# or Tariff# to use in Xbuilder.
Environment
Xenta 913 5.x.x
Xbuilder 5.x.x
Cause
Manufacturers of meters which utilize the M-Bus protocol may not specify the Storage# or Tariff# needed by Xbuilder. They may instead include DIF or DIFE information regarding their meter points. These codes correspond to the M-Bus protocol and indicate the Storage# and Tariff# of the data.
Resolution
Use the M-Bus DIF calculator to parse the data type, Storage#, and Tariff# of the data point. This spreadsheet should be sufficient for the majority of applications, but some exceptions apply. The hexadecimal codes for the data point must be provided by the manufacturer for the calculator to be useful.
