Notes
The UMG 96RM-E has its own Ethernet interface, so it is read directly over Modbus TCP (port 502, slave address 1 by default). Every row is the "Frequently required readings" block of Janitza's "UMG 96RM-E - Modbus-address list and Formulary", document 1.040.085.8.o (07/2025, from firmware 3.01 / hardware release 104), published at https://assets.janitza.com/ce18jq9ih0x6/b80ca06dda38d37f864115/703a1d1d3014935a5c3327ed6b978d37/janitza-mal-umg96rme-en.pdf ; the addresses are used as wire addresses (the list itself says the Little-Endian variant is the same address + 32768, so this is the Big-Endian, high-byte-first layout). All values are IEEE-754 single precision floats read with function code 03 and refreshed every 200 ms. Float and integer measured values already include the set current/voltage transformer factors; the short (16-bit) block does not. The list is deliberately limited to the frequently used measurements plus THD: harmonics 2-63, minimum/maximum/mean values, drag indicators, limit-value monitoring, logos and the 10000/10002 configuration registers (transformer ratios, nominal values, Modbus settings) are documented in the same address list. Everything listed here is read-only.
