Hitachi SJ100/L100/SJ200/L200 drive

Register map(s) for this device, with a note of how far each has been checked. Addresses are 0-based, as on the wire. Scale and byte order are confirmed only at the hardware-verified rung.

coherence-checked

Round-trips through a real Modbus stack with no overlapping addresses and a word-order-sensitive codec — the map is internally coherent and wire-decodable. Does NOT prove byte-order or scaling match a real device: the emulator is seeded from the map's own types, so a uniformly wrong byte-order still round-trips. Only hardware-verified confirms byte-order/scale on the wire.

field reports — community-sourced, unverified (checked 2026-06-11)

Register address offset: Users must use 0-based addressing (subtracting 1 from the documentation's 1-based start addresses) to avoid reading/writing incorrect registers. [source]
Coil mapping / Alarm trip issue: Writing to the third coil (thinking it is a direction command) actually triggers an external trip command (alarm) on the VFD because of a mismatch/inconsistency in register/coil numbering. [source]
confirmed: Supports MODBUS/TCP communication protocol with function codes 3, 4, 6, 16 — confirmed by SJ/L-EN Ethernet Communications Module Instruction Manual (HAL1052) [1.2.9]
confirmed: Physical connectors include RJ45 (marked ETHERNET) and RJ11 (marked SERIAL) with RJ11-to-RJ45 connection to the inverter — confirmed by SJ/L-EN Ethernet Communications Module Instruction Manual (HAL1052)
confirmed: Requires 24 VDC via terminals marked '+ 24 V -' — confirmed by SJ/L-EN Ethernet Communications Module Instruction Manual (HAL1052)
confirmed: Terminals are marked 'Power Alm Rly +24V- GNDC CM NC NO' — confirmed by SJ/L-EN Ethernet Communications Module Instruction Manual (HAL1052)
confirmed: Max read registers is 125 — confirmed by SJ/L-EN Ethernet Communications Module Instruction Manual (HAL1052)
confirmed: Register map matches 0-based start addresses of 32-bit parameters (e.g., output_frequency_monitor at 3000, run_mode at 8000) — confirmed by SJ/L-EN Ethernet Communications Module Instruction Manual (HAL1052)

The trust ladder

Each rung states what it proved and what it did not. Gray until proven; green is earned by hardware only.

generated — A prompt produced it. Unproven — anyone can regenerate this.
structure-verified — Decode path is structurally sound (addresses, widths, finite values). Does NOT prove word order or scaling.
coherence-checked — Round-trips through a real Modbus stack with no overlapping addresses and a word-order-sensitive codec — the map is internally coherent and wire-decodable. Does NOT prove byte-order or scaling match a real device: the emulator is seeded from the map's own types, so a uniformly wrong byte-order still round-trips. Only hardware-verified confirms byte-order/scale on the wire.
hardware-verified (software-key) x1 — Matched a real device with operator-attested readings as ground truth — the only rung that confirms word order + scaling on the wire.
