Humidifier SKS4-Modbus Guide-211019

Introduction

The SKS4 Modbus Communication Module User Guide provides information for using Neptronic ® communication feature. The controller uses Modbus communication protocol over the serial line in the RTU mode and provides a Modbus network interface between client devices and Neptronic SKS4 devices.
The SKS4 Modbus Guide assumes that you are familiar with Modbus terminology.
The following are the requirements for Modbus:

Data Model. The SKS4 Steam to Steam Humidifier Modbus server data model uses only the Modbus Registers table.
Register Address:
o As per protocol base (base 0); for PLC add 1 to the protocol base.
o As per holding register (base 400001).

Note: Ensure that the Modbus communication software used does not have a limit on the range of the register addresses that can be viewed and supports 6-digit holding registers.

Function Codes. The SKS4 Steam to Steam Humidifier 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 SKS4 Steam to Steam Humidifier Modbus server supports the following exception codes:
o Illegal data address
o Illegal data value
o Slave device busy
Serial Line. The SKS4 Steam to Steam Humidifier 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 SKS4 Steam to Steam Humidifier device only answers at the following address:
o The device’s unique address (1 to 246) can be set through the device menu or through holding register index 0.
