   document: >
       Units of measurement for  AnalogItems that represent continuously- variable physical quantities   ( e.g.,
       length, mass , time, temperature )
       NOTE  This standard defines Properties to inform about the unit used for the  DataItem
       value and about  the highest and lowest value likely to be obtained in normal operation

  fields:

            Identifies the organization (company, standards organization) that defines the EUInformation.

    unitId: >
            Identifier for programmatic evaluation. −1 is used if a unitId is not available.
            The displayName of the engineering unit is typically the abbreviation of the
            engineering unit, for example ”h” for hour or ”m/s” for meter per second." +
