Special Notes
Note 1: The address of each component will depend on which components are selected during the
configuration of the meter (using the AFC Manager). If less than 24 components are selected, they
are packed to remove unused component elements in the Analysis Block. The relative order of the
selected components is maintained and the overall size of the Analysis FB remains unchanged
(With firmware version 2.05 and later, you may choose to receive the analysis unpacked
regardless of the component selection; see the descriptions of Site Option bits 13 and 14 for more
information about the packing of analyses)
Note 2: The component mole fractions are entered as scaled integers. A component mole fraction
of .0753 (7.53 mole percent) is entered as the integer value 753. This number is internally divided
in the AFC module by 10,000.
Note 3: Refer to Function Block Structure (page 168) for information on Bit 8 and 9 settings.
