| 7 | === General information === | ||
| 8 | |||
| 9 | The BMS Mini device provides the information about the battery system using Modbus protocol. The BMS is a Modbus-server and it responds to the Modbus-client’s commands. | ||
| 10 | |||
| 11 | Interaction with the device is performed over the RS-485 bus (Modbus RTU) or the Ethernet network (Modbus TCP). | ||
| 12 | |||
| 13 | RS-485 bus connection parameters: | ||
| 14 | |||
| 15 | * baud rate, bps — 600, 1200, 2400, 4800, 9600 (by default), 19200, 38400, 57600, 115200; | ||
| 16 | * word length, bits — 8; | ||
| 17 | * parity — none; | ||
| 18 | * device address (by default) — 32. | ||
| 19 | |||
| 20 | Ethernet connection parameters: | ||
| 21 | |||
| 22 | * port — 502. | ||
| 23 | |||
| 24 | There is a description of the Input и Holding registers below. Column "Type" contains method of parameters coding: | ||
| 25 | |||
| 26 | * U8 — unsigned 8-bit integer number; | ||
| 27 | * U16 — unsigned 16-bit integer number; | ||
| 28 | * S16 — signed 16-bit integer number; | ||
| 29 | * U32 — unsigned 32-bit integer number; | ||
| 30 | * REAL32 — single precision floating point number ([[IEEE 754>>url:https://ru.wikipedia.org/wiki/IEEE_754]] standard); | ||
| 31 | * U8[x] — array of unsigned 8-bit integer numbers having a length of x; | ||
| 32 | * U16[x] — array of unsigned 16-bit integer numbers having a length of x; | ||
| 33 | * REAL32[x] — array of single precision floating point numbers having a length of x. | ||
| 34 | |||
| 35 | Words are in the **little endian**. | ||
