    "Schneider Electric Acti9 iEM3000 energy meters with Modbus RS-485 (iEM3150/3155, iEM3250/3255, iEM3350/3355).",
    "Addresses are the manual's register numbers (address on the wire = register - 1).",
    "The meter only supports FC03 (read) and FC16 (write). Settings marked WC in the manual are changed through the command interface (registers 5250+), so they are listed here as read-only.",
    "Rows marked \"not on iEM3x50\" only exist on the iEM3155 / iEM3255 / iEM3355.",
    "Tested on an iEM3250 and an iEM3155, both hardware revision 1.0.0 and firmware 14002, read over a Modbus TCP gateway, November 2026: all 81 registers read without errors on each. Checked: identification (name, model, manufacturer, serial number), setup, communication, currents, voltages, frequency, power, power factor, the 64-bit energy counters and their float copies (iEM3155: 127432214 Wh = 127432.21875 kWh), and the phase energies. On the iEM3155, L1 + L2 + L3 active power (2.5512 kW) equals the total, and active / apparent power (2.5512 / 4.0854) gives the power factor 0.6245 that the meter reports.",
    "On the iEM3250 the rows marked \"not on iEM3x50\" read NaN (floats) or 0xFFC00000; on the iEM3155 they read values (reactive and apparent power, energy export, the reactive phase energies, the four rates, which were 0 because multi-tariff is disabled). Both meters answer FC17 with illegal function.",
    "Not verified: the meaning of diagnostic codes 204 and 205 (code 205 was active on both meters, and 204 also on the iEM3250), and Digital input status (8906), which read 0x00008000 on the iEM3155 and 0xFFC00000 on the iEM3250: the 32-bit value does not fit the description of bit 1 given for it, and the state of the input was not known."
