Introduction
The TUCB & TUHB Series Modbus Communication Module User Guide provides information for using the Neptronic®
controller communication feature. The uses Modbus communication protocol over serial line in the RTU mode and
provides a Modbus network interface between client devices and Neptronic TUCB & TUHB Series devices.
The TUCB & TUHB Series Modbus Guide assumes that you are familiar with Modbus terminology.
The following are the requirements for Modbus:
•Data Model. The controller Modbus server data model uses only the Holding Registers table.
•Function Codes. The controller Modbus server supports a limited function codes subset comprising:
oRead Holding Registers (0x03)
oWrite Single Register (0x06)
oWrite Multiple Registers (0x10)
•Exception Responses. The controller Modbus server supports the following exception codes:
oIllegal data address
oIllegal data value
oSlave device busy
•Serial Line. The controller Modbus over serial line uses RTU transmission mode over a two-wire configuration
RS485 (EIA/TIA-485 standard) physical layer.
oThe 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.
oThe supported baud rates are 9600, 19200, 38400, and 57600.
oThe 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.
oIn 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 controller device only answers at the following address:
oThe device's unique address (1 to 246) that can be set through the device menu or through holding register index
0.
