It is the same as how do we deal with the air condition system to deal the temperature in our house. The plant-floor the operator uses an HMI to check the temperature of an industrial water tank.

HMI system is used by a number of Industrial Organizations. There is a lot of company use HMI to deal with machines. It optimizes their industrial processes. Industries using HMI and it is including:

• Energy
• Food and Beverage
• Manufacturing
• Oil & Gas
• Power
• Recycling
• Transportation

Water and many more

The common roles of HMI are that it interacts with operators, system integrators, engineers, main control system engineer. HMI is an essential resource for them who use it for and check processes. They also diagnose problems and visualize data.

The use of HMI is, it communicates with PLC and input, output sensors. So, HMI can get and display information for the user to view. HMI can use for the purpose of a single function. Like as, checking and tracking. HMI can perform complex operations. Switching machines, increasing production speed possible by HMI. Before inventing HMI, operators need to check the mechanical progress physically. And need to record the report on a piece of paper or a whiteboard.

A lot of advantages is provided by HMI (Human Machine Interface). These are the following:

• Error reduction
• Increased System, and user efficiency
• Improved reliability and maintainability
• Increased user acceptance and comfort

• DOP-B Series
• DOP-W Series
• TP HMI
