1Overview
NCS-MH105 Converter is a new R&D converter between MODBUS-RTU protocol and HART
protocol. As MODBUS host, NCS-MH105 converter communicates with the device with
MODBUS-RTU communication function via RS485 interface, and it is able to convert the data in
the device to HART device variable output, supporting 4~20mA current output. NCS-MH105
converter is shown as Figure 1:
Figure 1 NCS-MH105 Converter
As a HART device, NCS-MH105 converter and PC can make up HART system via HART
modem. It is able to configure NCS-MH105 converter parameters via HART configuration
software, shown as Figure 2.

3Structure and Working Principle
NCS-MH105 Converter supports 4 dynamic variables, 6 device variables. Via MODBUS register,
the data selected by MODBUS device is configured to NCS-MH105 Converter device variables,
and then it enters the mapping from device variable to dynamic variable, as the device output,
supporting 4~20mA analog signal output. NCS-MH105 Converter principle is shown as following

The mechanism size of NCS-MH105 converter is 96 mm*56 mm, which not only matches
standard Adam module housing, also can be installed to device through positioning hole, shown as
Figure 4.

HART Bus gives power supply to NCS-MH105 converter. RS485 electrical interface requires an
external 5V power supply. It is recommended to use twisted-pair with shield, which improves
device anti-electromagnetic capacity. According to the wiring method above, the system is
powered on, firstly, the system will be self-testing, which will carry out system initialization,
protocol initialization, etc., and then starts to work.
4.1 MODBUS Parameter Setting
MODBUS communication parameter of NCS-MH105 converter is carried out via SDC625
configuration software, shown as Figure 5:
