Schneider Electric · ModbusSchneider iEM3355

Read-only starter map for the Schneider Electric iEM3355 Modbus RTU meter. It contains 29 Float32 measurements from the current DOCA0005EN-16 manual: current, voltage, active/reactive/apparent power, power factor, frequency and active/reactive import and export energy.

Prove the decode before rollout

This file is intentionally scoped to product code iEM3355 so Edge's exact product-code compatibility gate can match it safely. Do not rename or apply it to another iEM model, or to similarly named LonWorks, M-Bus or BACnet variants; those require their own exact-code templates.

The manual's Address column is the hexadecimal 16-bit value sent in the Modbus frame, while Register is one-based decimal (register = address + 1). Edge sends the PDU address directly, so documented register 3000 at 0x0BB7 is start_address 2999.

All selected rows are read-only Float32 holding registers read with function code 03. The pinned mbmd iEM3000 implementation decodes the same measurement addresses as network-order IEEE-754 (high byte and high word first), represented in Edge as big-endian with word_swap false and byte_swap false. Compare a stable non-zero voltage, current and energy value with the front-panel display before rollout.

Tariff counters, input metering, digital I/O and writable configuration are excluded even though some are available on the iEM3355. Line-to-neutral measurements require an installation with a neutral reference. Applying this template replaces the selected Modbus device's current sensor list; connection, unit ID and export identifiers remain site-specific.

Applying the file replaces the selected device's current Modbus sensor list. It does not change the Gateway connection, server address, Modbus unit ID, device enable state or export identifiers.

What the download changes

When applied in Edge, the file replaces the selected device's current Modbus sensor list with these 29 read-only points. It does not change the Gateway connection, server address, Modbus unit ID, device enable state or export identifiers. Back up or duplicate a customised definition before applying it.

Import, apply, then prove one known value

1
Download the reviewed JSON
Sign in with an account that has approved Edge download access.
2
Import in Edge
Open Settings → Device Templates, choose Import, and select the downloaded file.
3
Apply to the exact model
Use a new or backed-up device definition, then choose its existing Gateway connection and unit address. Applying the template replaces that definition's current sensor list.
4
Commission before rollout
Check identity, value, unit and timestamp against one known condition before enabling exports or repeating the setup.
