TSUB Series Universal Wall-Mount Controller

“`html

Specifications:

Model: TSUB Series Modbus Communication Module
Supported Baud Rates: 9600, 19200, 38400, 57600
Unique Address Range: 1 to 246
Parity Control Options: No parity, Even parity, Odd parity
Stop Bit Options: 1 stop bit, 2 stop bits

Product Usage Instructions:

Setting Baud Rate and Parity Control:

Access the Modbus Comport Config device menu or holding
register index 2.
Select the desired baud rate from the available options (9600,
19200, 38400, 57600).
Choose the appropriate parity control setting (No parity, Even
parity, Odd parity).

Setting Unique Address:

Access the device menu or holding register index 0.
Set a unique address between 1 to 246 for the device.

Reading and Writing Registers:

To read holding registers, use function code 0x03.
To write a single register, use function code 0x06.
To write multiple registers, use function code 0x10.

Frequently Asked Questions (FAQ):

Q: What should I do if I encounter an “Illegal data address”

error?

A: Check the address being accessed and ensure it falls within
the valid range for the device.

Q: How can I change the baud rate of the device?

A: Access the Modbus Auto Baud Rate device menu or holding
register index 1 to modify the baud rate settings.

Q: What is the default baud rate detection method?

A: The default method is automatic baud rate detection, but you
can switch to fixed baud rate selection if needed.

Universal Wall-Mount Controller
Modbus Communication Module User Guide
Introduction
The TSUB Modbus Communication Module User Guide provides information for using Neptronic® TSUB communication feature. The TSUB uses Modbus communication protocol over serial line in the RTU mode and provides a Modbus network interface between client devices and Neptronic TSUB Series devices. The TSUB Modbus Guide assumes that you are familiar with Modbus terminology. The following are the requirements for Modbus:
· Data Model. The TSUB Modbus server data model uses only the Holding Registers table. · Function Codes. The TSUB 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 TSUB Modbus server supports the following exception codes:
o Illegal data address o Illegal data value o Slave device busy
· Serial Line. The TSUB 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 TSUB 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.
