ZIGBEE ETHERNET GATEWAY DATA CONTRACT AND BENCH TEST
Companion: https://yenra.com/zigbee-ethernet-gateway/
Prepared September 8, 2026. Read-only integration planning on approved equipment.

INSTRUCTIONS
Fill every address and field from the exact manufacturer's documentation. A
radio or Ethernet connection alone does not establish application compatibility.
Do not use the fictional example below as a real device register map.

Gateway / firmware / manual revision / operating mode:
Sensor or serial endpoint / firmware / supported function evidence:
Ethernet API/protocol and security / allowed clients / management path:
Wireless role / device identity / gateway-side identity mapping:

COPY PER VALUE
Measured quantity / unit:
API field or Modbus function code / unit ID / zero-based protocol address:
Register count / manual's displayed address convention:
Data type / signedness / byte order / multi-register word order:
Scale / offset / invalid-value convention:
Measurement time / receipt time / reporting interval:
Quality flag / maximum data age / stale-data behavior:
Known input / raw read / calculated value / observed application value:

FICTIONAL EXAMPLE ONLY
Function 04, input-register protocol address 0, signed 16-bit, scale 0.1 C/count.
234 -> 23.4 degrees C; -55 -> -5.5 degrees C.
A separate hypothetical quality/time contract marks old data stale even if the
cached value remains readable. These fields are not an ICP DAS register map.

BENCH TEST LOG
Timestamp/timezone / test / expected outcome / actual outcome / evidence:
Known normal, negative or boundary input:
Incorrect address or documented protocol exception:
Sensor-report interruption and stale indication:
Ethernet interruption and timeout behavior:
Reconnection / buffered records / original timestamps / duplicates:
Polling interval / retries / outstanding requests and capacity evidence:
Correction / retest / acceptance decision:

RETAIN
Completed map, exact models/versions, manual, approved configuration and owner.
Recheck after sensor, gateway, firmware or application changes. Consult the
Modbus specification and exact gateway manual linked from the companion guide.
