Admin 3.1 1 == 4.2.1 General information ==
Admin 1.1 2
3 The BMS Main 2.x 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.
4
5 Interaction with the device is performed over the RS-485 bus (Modbus RTU) or the Ethernet network (Modbus TCP).
6
7 RS-485 bus connection parameters:
8
9 * baud rate, bps — 600, 1200, 2400, 4800, 9600 (by default), 19200, 38400, 57600, 115200;
10 * word length, bits — 8;
11 * parity — none;
12 * device address (by default) — 32.
13
14 Ethernet connection parameters:
15
16 * port — 502.
17
18 There is a description of the Input и Holding registers below. Column "Type" contains method of parameters coding:
19
20 * U8 — unsigned 8-bit integer number;
21 * U16 — unsigned 16-bit integer number;
22 * S16 — signed 16-bit integer number;
23 * U32 — unsigned 32-bit integer number;
24 * REAL32 — single precision floating point number ([[IEEE 754>>url:https://ru.wikipedia.org/wiki/IEEE_754]] standard);
25 * U8[x] — array of unsigned 8-bit integer numbers having a length of x;
26 * U16[x] — array of unsigned 16-bit integer numbers having a length of x;
27 * REAL32[x] — array of single precision floating point numbers having a length of x.
28
29 Words are in the **little endian**.
