neptronic SKG4 Gas Fired Humidifier
Introduction
The SKG4 Modbus Communication Module User Guide provides information for using Neptronic® communication feature. The controller uses Modbus communication protocol over serial line in the RTU mode and provides a Modbus network interface between client devices and Neptronic SKG4 devices.
The SKG4 Modbus Guide assumes that you are familiar with Modbus terminology.
The following are the requirements for Modbus:
- Data Model. The SKG4 Gas Fired Humidifier Modbus server data model uses only the Modbus Registers table.
- Register Address:
- As per protocol base (base 0); for PLC add 1 to protocol base.
- 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 SKG4 Gas Fired Humidifier Modbus server supports a limited function codes subset comprising:
- Read Holding Registers (0x03)
- Write Single Register (0x06)
- Write Multiple Registers (0x10)
- Exception Responses. The SKG4 Gas Fired Humidifier Modbus server supports the following exception codes:
- Illegal data address
- Illegal data value
- Slave device busy
- Serial Line. The SKG4 Gas Fired Humidifier Modbus over serial line uses RTU transmission mode over a two-wire configuration RS485 (EIA/TIA-485 standard) physical layer.
- 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.
- The supported baud rates are 9600, 19200, 38400, and 57600.
- 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.
- 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 SKG4 Gas Fired Humidifier device only answers at the following address:
- The device’s unique address (1 to 246) that can be set through the device menu or through holding register index 0.
