Moxa ioLogik E1200 remote 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.

⚠ disputed: identification: firmware_register is 5029 — disputed by ioLogik E1200 Series User's Manual, which lists register 5029 as firmwareBuildDate (length 2 words), while the actual firmwareVersion is located at register 5024 (length 3 words) [10.4.1]

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

The user manual's appendix lists AI_scaledValue for the ioLogik E1240 at register 30521 (0-based address 520), but the actual device's default Modbus map uses register 30009 (0-based address 8). This discrepancy causes communication faults when using standard Modbus TCP instructions or Add-On Instructions (AOIs) configured according to the manual's appendix. [source]
When integrating the ioLogik E1242 with PLCs that only support signed 16-bit integers (such as the Allen-Bradley MicroLogix 1400), raw analog input values (which are unsigned 16-bit, 0-65535) will overflow and cause erratic or incorrect readings (e.g., reading 32767 at 12mA). [source]
confirmed: comms defaults (framing: TCP, default unit ID: 1) — confirmed by ioLogik E1200 Series User's Manual [1.1.2]
confirmed: physical characteristics (2 switched 10/100 Mbps RJ45 ports, 1.5 kV magnetic isolation, DIN rail or wall mounting, max 14 AWG I/O cable) — confirmed by ioLogik E1200 Series User's Manual
confirmed: environmental limits (operating temp: -10 to 60°C standard, -40 to 75°C wide temp; storage temp: -40 to 85°C; humidity: 5 to 95%) — confirmed by ioLogik E1200 Series User's Manual
confirmed: power requirements (12 to 36 VDC) — confirmed by ioLogik E1200 Series User's Manual
confirmed: register addresses (e1240_ai_raw_value_ch0 @ 0, e1240_ai_scaled_value_ch0 @ 8, e1241_ao_raw_value_ch0 @ 1024, e1241_ao_scaled_value_ch0 @ 0, e1242_ai_raw_value_ch0 @ 512, e1260_rtd_multiplied_value_ch0 @ 1536, e1260_rtd_scaled_value_ch0 @ 1548) — confirmed by ioLogik E1200 Series User's Manual

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.
