Weintek MT8071iE “Modbus RTU” Hitachi NE S1 Tutorial

Written by

Hello, in previous posts has guided you to use some types of PLC and HMI used to control Hitachi NES1 Inverter via Modbus-RTU, today I will continue to guide you to use HMI Weintek to control it simply and easily.

The HMI model Weintek uses is MT8071iE , both Weintek MT8071iE and Hitachi NE-S1 have a built-in RS485 port so we can connect them together via “Modbus RTU”.
