4. Introduction
This document, the Modbus Model Guide, describe Modbus register model of NILAN CTS-700.
5. General Provisions
In this chapter described general provisions of using Modbus protocol on NILAN CTS-700.
Columns description:
1. Register Number – Contain address of register in Modbus. (See Using PLC).
2. Slave ID – Contain slave address of target board (See System Device Addressing).
3. Function – Short description of register value.
4. R – Read permission (“+” - Reading is allow, “-” - Reading is deny).
5. W – Write permission (“+” - Writting is allow, “-” - Writting is deny).
6. Reset – If marked with “+” value will be applied after restart of the system.
7. Value – Contain all possible value of the register. Some of the register, which has Function “Apply value” must be write with specific key for applying of the parameter.
5.1. Addressing
Modbus client connect to a system using Modbus RTU over TCP/IP. It means that for connect to the system client must establish connection to board's IP address to port 502 Board's IP address by default set to 192.168.5.107 and can be changed by Modbus (See Fejl! Henvisningskilde ikke fundet.) or Touch Display.
5.2. Using PLC
In case using of PLC after connect need read register
the registers number (column 1) must be incremented for 1.
addressing changes no require.

5.3. System Device Addressing
The CTS-700 can include up-to 3 boards. Due of this to access to them must be used following slave ID:
5.4. Console application
For testing a Modbus register model were implemented console application. It is called Modbus Master Console. The Modbus Master Console provide possibility to read and write data trough Modbus. It is support Modbus functions: 3, 4, 6, 16. For connection should be used Board IP address and Slave board ID according to System Device Addressing. Register number must be used with any changes of address.
