Notes
UPS with the Eaton Gigabit Network Card (Network-M2 / INDGW-M2), which runs the Modbus/TCP server on port 502; the card is available for the 5PX, 9PX and 9SX families and for larger three-phase UPSs. Values come from the Eaton Master Modbus Register Map (document 164201391 Rev F): status bits are input status (function 02, 1xxxx numbering) and meters are input registers (function 04, 3xxxx numbering). Register numbers in this file are the supplier's 1-based register numbers, so register 1 is 30001 (wire address 0). All meter values are integers with the documented scale applied (/10 or /100). The master map is generic: the document warns that not all registers apply to all UPS models. This seed lists the core status bits and the output/input/battery meters; the bar-chart and service-only registers, the UPM 1-8 LED banks, the outlet/group alarm bits and the ESS/high-efficiency bit (input status register 4, which is 'Reserved' in Rev D of the master map and only appears as a named bit in the newer Rev F that is not publicly reachable) are left out.
