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. www.neptronic.com Page | 1 Universal Wall-Mount Controller Modbus Communication Module User Guide Holding Registers Table Table Glossary Name Description W RO Unsigned Signed Bit String Writable Register Read Only Register For range of values from 0 to 65,535, unless otherwise specified For range of values from -32,768 to 32,767, unless otherwise specified For registers with multiple values using bit mask (example, flags) Holding Register Table Name ASCII MSB LSB MSW LSW Description For registers containing ASCII (8-bit) characters Most Significant Byte Least Significant Byte Most Significant Word Least Significant Word Protocol Base 0 Register Index 40001 Description Address - Neptronic ID and Modbus address of current device. 1 40002 MSTP Baud Rate. 2 40003 Communication port configuration. 3 40004 ProdName_87, characters 8-7 of 8 name characters. 4 40005 ProdName_65, characters 6-5 of 8 name characters. 5 40006 ProdName_43, characters 4-3 of 8 name characters. 6 40007 ProdName_21, characters 2-1 of 8 name characters. 7 40008 Controller Product_Version, actual firmware version. 8 40009 Controller parameters version. 9 40010 System Status 1. www.neptronic.com Data Type Range Unsigned Unsigned Scale 100 Unsigned ASCII ASCII ASCII ASCII Unsigned Unsigned Bit String MSB = 22, LSB = 1-246 0, 9600, 19200, 38400, or 57600, 0 = Auto Baud Rate Detection Value/100 (e.g. 38400 baud = 384) 1 = No parity, 2 Stop bits, 2 = Even parity, 1 stop bit, 3 = Odd parity, 1 stop bit MSB = 84 (T), LSB = 85 (U) MSB = 67 (C), LSB = 66 (B) MSB = 50 (2), LSB = 52 (4) MSB = 32 (Space), LSB = 0 (Null) 1 to 65535 (e.g. 115) 1 to 65535 (e.g. 102) [B1, B5, B7 B15]: Reserved B0: System operation 0 = Normal, 1 = Fault B2: System override by NSB or OCC 0 = Normal, 1 = OFF B3: ChangeOverMode 0 = Cooling, 1 = Heating B4: AL_FlowSwitch 0 = No alarm, 1 = Alarm activated B6: AL_DirtyFilter 0 = No alarm, 1 = Alarm activated Writable W W W W W W W RO RO RO Page | 2 Protocol Register Base Index Description 10 40011 System Status 2. 11 40012 Internal temperature sensor reading. 12 40013 External temperature sensor reading. 13 40014 Changeover temperature sensor reading. 14 40015 Control temperature reading. 15 40016 Internal humidity sensor reading.
