MODBUS POINT MAP

The EM3555 Full Data Set (FDS) features data outputs such as demand calculations, per phase signed watts VA and VAR, import/export Wh and VAh, and VARh accumulators by quadrant. The Data Logging function adds log configuration registers 155-178 and log buffer reading at registers 8000-13760. The meter supports variable CTs and PTs, allowing a much wider range of operation from 90V x 5A up to 32000V x 32000A. To promote this, the meter permits variable scaling of the 16-bit integer registers via the scale registers. The 32-bit floating point registers do not need to be scaled.

Integer registers begin at 001 (0x001). Floats at 257 (0x101). Configuration registers at 129 (0x081). Values not supported in a particular System Type configuration will report QNAN (0x8000 in Integer Registers, 0x7FC00000 in Floating Point Registers). Register addresses are in PLC style base 1 notation. Subtract 1 from all addresses for the base 0 value used on the Modbus RS-485 link.
