5 == Modbus protocol ==
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**.
