Description

TG765-XT-C The human machine interface, often abbreviated as HMI, refers to a dashboard or screen used to control equipment. Industry line operators, managers and supervisors rely on HMI to translate complex data into useful information. For example, they monitor equipment using HMIs to make sure it is working properly.

Advantages

Unlike just a PLC, an HMI provides real-time feedback, turns off the alarm set and modifies the system without the need for reprogramming.
The main advantage of HMI over PLC is that functionality HMIs can be used for both simple and complex tasks.
Users can design an HMI's user interface to suit their needs.

Disadvantages

Sometimes the design of HMI can create confusion between operator and machine and it can create big error and this confusion is due to HMI design.
