Information | 1

1 Information
Modbus is a serial communication protocol used for transmitting information over serial lines between electronic devices. The device requesting the information is called "Master", while devices supplying the requested information are "Slaves". When it comes to planning data communication for open, multi-vendor industrial control systems, Modbus is the first choice of end users and integrators alike.
The Modbus/RTU protocol defines how a "master" device polls one or more "slave" devices to read and write data in real time by means of RS232, RS422, or RS485 serial data communication. Modbus/TCP, an extension of Modbus/RTU, defines how Modbus/RTU and Modbus/ASCII messages are encoded within and transported over TCP/IP-based networks. Modbus/TCP is just as simple to implement and flexible to apply as the original Modbus/RTU.

1.1 Physical layer
New Systemair controls have standard and readily available Modbus/RTU over three-wire (A, B and GND) RS485 on the Connection Board (CB) and Modbus/TCP over TCP/IP using Internet Access Module (available as an accessory - Art. No. 211243). For Modbus/TCP connection over TCP/IP using Internet Access Module refer to the IAM quick guide.
Slave address: 1 to 247 Baud rate: 9600 to 115200 Parity: None, Even, Odd Stop bits: 1 (fixed)
Parameters can be changed in Modbus page (Service -> Communication -> Modbus) in the Control Panel.

1.2 Transmission modes
The registers are Input registers (read-only) and Holding registers (read-write) when using Modbus/RTU and Holding registers (read-write) when using Modbus/TCP.
All registers are 16 bit Integers.
