Chromalox 6060 controller (Modbus supplement)

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 only confirmed at the hardware-verified rung.

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): RTU; baud 2400/4800/9600/19200/38400; FC 03,04,06,08,16; The max. length of a message may not exceed 256 bytes.

bench facts as documented (unverified)

terminals	pins of connector B on the rear, via flat-pin connectors or via screw terminals dependent on version
A/B polarity	for signal 1 (off) Data A is positive to Data B, for signal 0 (on) Data A is negative to Data B
termination	Terminating resistors usually have a value of approx. 120 ohms, and are connected in parallel between the data lines A and B
wiring notes	GND lead can be grounded at one point via a resistor 'RGND' (100 ohms, 1/4 watt).
broadcast	supported
protocol notes	If a parity error is detected upon receipt of a message, the receiving device will not generate an answer.
model register	203
firmware register	201
FC 43 device ID	not supported
environment	If possible, the place of installation should be exempt of vibration, aggressive media (e.g. acid, lye), liquid, dust or aerosol.
certifications	The device is not certified for installation in explosion-hazarded areas.

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.

Have a device that isn't here? Upload its register map — generation is free, and the connector earns its rung by being proven, not claimed.

Need it proven on your own device? Hardware verification — if it doesn't verify, you don't pay.

Building a platform? License the verified library — machine-readable maps, firmware matrix, API access.
