 "summary": "The UMG 509-PRO is a Janitza power quality analyser with a fourth voltage and current channel, an RS-485 port and network (IP) settings. Measurements are big-endian 32-bit floats; the 19000-19120 'frequently required readings' block is the same one used across Janitza meters. This map covers that block, the fourth channel, total power factor, consumed energy, digital I/O, transformer ratios and identity/network settings, with access rights as printed in the list.",

  "Left out: the energy delete commands 14141/14142 (_DEL_WH/_DEL_QH) because the list says '1 = delete' but marks them read-only (RD), so write access is unclear.",
