4.2.6.6 Register Definitions (cont.)
Table 8 below shows the registers that are available with the energy meter firmware.
Registers
30527-30528 Totalizer #2
32043-32048 Totalizer #2 units
30003-30004 Temperature #2
30011-30012
Table 9 below shows the registers that contain the display units strings:
Registers
32007-30012 Volume Flow units
32001-32006 Mass flow units
32025-32030 Temperature units
32019-32024 Pressure units
32031-32036 Density units
32013-32017 Energy flow units
Function codes 03 (read holding registers) and 04 (read input registers) are the only codes supported for reading
these registers, and function codes for writing holding registers are not implemented. We recommend that the
floating point and long integer registers be read in a single operation with the number of registers being a multiple of
two. If this data is read in two separate operations, with each reading being a single 16-bit register, then the value will
likely be invalid.
The floating point registers with values in display units are scaled to the same units currently displayed, but they are
instantaneous values that are not smoothed. If display smoothing is enabled (non-zero value entered in the Display
TC item in the Display Menu), then the register values will not agree exactly with the displayed values.
