Solcon RVS-DX soft starter

Register map(s) for this device, each at the trust rung it earned. Addresses are 0-based as on the wire. Word order and scaling are confirmed at the hardware-verified rung and at no rung below it.

interop-verified

Read + decoded cleanly over a real network vs an independent third-party Modbus test server (transport and framing; reads are remapped into the server's register window, so the map's own addresses are NOT exercised). Does NOT prove word order/scaling against the actual device.

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%.
certifications	UL, cUL, CE, GOST-R
doc revision	Ver. 26/12/2012

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.
interop-verified — Read + decoded cleanly over a real network vs an independent third-party Modbus test server (transport and framing; reads are remapped into the server's register window, so the map's own addresses are NOT exercised). Does NOT prove word order/scaling against the actual device.
simulator-verified — Decoded correctly against a protocol emulator seeded with known-true values — catches word-order/scaling errors vs the emulator, not the physical device.
hardware-verified x1 — Matched a real device with operator-attested readings as ground truth — the only rung that confirms word order + scaling on the wire.

If your device isn't here, upload its register map. Generation is free, and the connector keeps the rung it earns under testing.

To prove a connector against your own device, order hardware verification. If it doesn't verify, you don't pay.

Platform builders can license the verified library: machine-readable maps, the firmware matrix, API access.
