Sources and notes
- Manual de Configuração e Operação - Balança de Fluxo · version 0053.MN.02.A Section 6.1; supplied with the map request

- Modbus TCP on port 502. The device sends 13 signed integer registers starting at register 200.
- The manual names the 32-bit values Hi and Lo in that order (200 Hi, 201 Lo), so the word order is big. It does not state the unit or the decimals of the weight, flow and accumulated value; values are raw.
- The data table is shown on the controller: Menu, CLP configuration (maintenance password in the manual), Ethernet parameters, Data table.
| Area | Address | Name | Type | Access | Unit | Scale | Description |
|---|---|---|---|---|---|---|---|
| HR | 200 | int32 ABCD | R | Current weight, high word first (register 200 Hi, 201 Lo) | |||
| HR | 202 | int32 ABCD | R | Current flow, high word first | |||
| HR | 204 | int16 | R | ||||
| HR | 205 | int32 ABCD | R | Accumulated value, high word first | |||
