11. BMS engineering

11.1. Connection to SchwankControl control unit

 Stubs should always be avoided

 Modbus data lines: A+, B-, COM

11.2. SchwankControl configuration

 SchwankControl = Modbus slave, BMS = Modbus master.

 Set the SchwankControl address. The SchwankControl can be accessed within the BMS Modbus

at this address.

 Expert: Configuration - More - Modbus slave address.

0 = auto

Modbus slave addr. corresponds to control address [1-8]

Modbus slave addr. freely selectable from 1-254

11.3. Modbus register description [without adapter]

On request, we will provide you with the required files.

A Modbus program such as mbpoll is required.

RS485 parameters:

Physical RS485 Baud rate 19200 kBaud Parity None Data bits 8 Stop bits 1

11.4. BMS connection via Modbus adapter

Available converters, see also section 14:

 40660130 - BMS converter, MODBUS RTU to MODBUS TCP

 40660140 - BMS converter, MODBUS RTU to BACNet/IP

 40660150 - BMS converter, MODBUS RTU to KNX
