ICP DAS ET-7000/PET-7000 I/O

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.

  • Since Firmware version 3.11 or later, factory default credentials are no longer supported, requiring manual creation on first login. [source]
  • An 'Invalid IP Address' error message may be displayed in the Network Settings configuration page when using Mozilla Firefox or SeaMonkey browsers. [source]
  • The module fails to retrieve or authenticate the account and password when the credential length is exactly equal to 8 characters. [source]
  • confirmed: Default Unit ID is 1, framing is TCP on port 502, and supports function codes 1, 2, 3, 4, 5, 6, 15, 16 — confirmed by ET-7002/PET-7002 User Manual and ET-7x00 Series Register Table
  • confirmed: Firmware version register is 30351 (0-based 351) and Module Name register is 40559 (0-based 559) — confirmed by ET-7x00/PET-7x00 Series Register Table
  • confirmed: Analog Input accuracy is +/-0.1% (Normal) / +/-0.5% (Fast) and operating temperature is up to 75°C — confirmed by ET-7000 Series Specifications
  • confirmed: CJC Temperature is mapped to 0-based register 143 (30143) — confirmed by ET-7018Z/PET-7018Z Modbus Address Mapping

The trust ladder

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

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.
