MAC/MTA E700 HMI is the abbreviation of human-machine interface. As the acronyms imply, these panels provide a visual interface between machines, equipment and processes as well as between operators or engineers.
Most factories use multiple HMI panels at a convenient location for the operator, and each panel is configured to provide the data required by the operator at that location.

Features of HMI panel:
1) Display size
The first thing to consider is the display size. Do I need a panel with a small screen (such as 3 or 4 inches diagonal) or a larger screen (such as 15 or 21 inches)? HMI panels are available in various sizes, usually from 3 inches to 25 inches.
2) Touch screen?
Do I want a touch screen? Touch screens are convenient and responsive, but they are more expensive than models with only function keys and arrow keys.
3) Color or monochrome?
Do I need color or monochrome? The color HMI panel is vivid and can easily display the status in color, but the monochrome unit costs less and is very effective when displaying a small amount of data (such as speed feedback or batch remaining time).
4) Resolution
What screen resolution is required to display enough drawing object details or allow multiple objects to be displayed on the same screen?
5) Installation
How about installation? Should the HMI be flush mounted in the panel? Or on the base? Or handheld?
6) Protection
What protection does the human-computer interface need? IP67 to prevent liquid splashing or outdoor installation?
7) Interface
What interface do I need? Ethernet? PROFINET? Serial interface for laboratory instruments, RFI scanners or barcode readers? Do I need multiple interface types?
8) Software requirements
What are my software requirements? Do I need OPC or special driver to access the data in my controller?
9) Custom program?
Do I need to run custom programs on HMI terminals to support factory operations, such as barcode software or inventory application interface?
10) Support Windows?
Does the HMI need to support Windows and its file system, or is the vendor's HMI application sufficient?
