Product Information

Specifications:

Product Name: Universal Wall-Mount Controller TUUB Series
Modbus Communication Module
Supported Baud Rates: 9600, 19200, 38400, 57600
Address Range: 1 to 246

Product Usage Instructions:

Modbus Communication:

The Modbus Communication Module allows for various operations
including:

Read Holding Registers (0x03)
Write Single Register (0x06)
Write Multiple Registers (0x10)

Baud Rate and Configuration:

The physical layer supports fixed baud rate selection or
automatic baud rate detection. Supported baud rates are 9600,
19200, 38400, and 57600. Parity control and stop bit configuration
can be adjusted through the Modbus Comport Config device menu.

Device Addressing:

The device’s unique address can be set from 1 to 246 through the
device menu or holding register index 0.

Holding Registers Table:

The holding registers table provides detailed information on
register indexes and their corresponding descriptions. It includes
various parameters such as communication port configuration, system
status, internal and external temperature sensor readings.

FAQ:

Q: How can I change the baud rate of the Modbus Communication

Module?

A: You can change the baud rate through the Modbus Auto Baud
Rate device menu item or holding register index 1.

Q: What is the range of supported baud rates?

A: The supported baud rates are 9600, 19200, 38400, and
57600.

Universal Wall-Mount Controller
Modbus Communication Module User Guide
Introduction
The TUUB Modbus Communication Module User Guide provides information for using Neptronic® TUUB communication feature. The TUUB uses Modbus communication protocol over serial line in the RTU mode and provides a Modbus network interface between client devices and Neptronic TUUB Series devices. The TUUB Modbus Guide assumes that you are familiar with Modbus terminology. The following are the requirements for Modbus:
· Data Model. The TUUB Modbus server data model uses only the Holding Registers table. · Function Codes. The TUUB Modbus server supports a limited function codes subset comprising:
o Read Holding Registers (0x03) o Write Single Register (0x06) o Write Multiple Registers (0x10)
· Exception Responses. The TUUB Modbus server supports the following exception codes:
o Illegal data address o Illegal data value o Slave device busy
· Serial Line. The TUUB Modbus over serial line uses RTU transmission mode over a two-wire configuration RS485 (EIA/TIA-485 standard) physical layer.
o The physical layer can use fixed baud rate selection or automatic baud rate detection (default) as per the Modbus Auto Baud Rate device menu item or holding register index 1.
o The supported baud rates are 9600, 19200, 38400, and 57600. o The physical layer also supports variable parity control and stop bit configuration as per the Modbus Comport
Config device menu item or holding register index 2. o In auto baud rate configuration, if the device detects only consecutive bad frames (2 or more) for one second with
any given baud rate, it will reinitialize itself to the next baud rate.
· Addressing. The TUUB device only answers at the following address:
o The device’s unique address (1 to 246) that can be set through the device menu or through holding register index 0.
