6 | |||
7 | === General information === | ||
8 | |||
9 | The BMS Main 3 device provides 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 | The 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 parameter 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 | The bytes order of the word is **little endian**. | ||
