Solcon RVS-DX soft starter

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.

link settings as documented (unverified): default 9600 8E?; Standard RS485, Half Duplex with MODBUS Protocol. Terminals (-) & (+) must be wired to control supply for operation in communication mode. Leave terminal NC not connected.

⚠ Do not interchange line and load connections. Operating at surrounding air temp. higher than 40°C may cause damage to the starter. — Starkest reads only; we never write a control register.

bench facts as documented (unverified)

terminals	out(-), Out(+)
shield/ground	Twisted shielded pair should be used, connect shield to ground a PLC/Computer side.
wiring notes	Use twisted shielded pair.
protocol notes	MODBUS TIME OUT range is 0.1-60 SEC., default is OFF.
power	Control Voltage: 230VAC +10%-15% or 115VAC +10%-15%, 50/60 Hz. Mains Voltage: 230-600V or 690V (for RVS-DX 390A and up), 50/60Hz.
environment	Operating temperature range: -10°C to +40°C. Relative non-condensed humidity inside the enclosure should not exceed 95%.

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.
