1. System Overview
NCS-MH105 converter is a newly 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.
As a HART device, NCS-MH105 converter can get through HART system with HART modem and PC. It is able to configure parameters of NCS-MH105 converter via HART configuration software, shown as Figure 2.
