Description

EXP40-TTA/DC HMIs allow operators to start and stop cycles, adjust set points, and perform other functions necessary to adjust and interact with the control process. Since HMI is software-based, they replace physical wires and controls with software parameters, allowing them to be easily adapted and adjusted.

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.
• It can create big error and this confusion is due to HMI design.
