说明：  触摸屏作为一种人机界面，是操作人员和机械设备之间做双向沟通的桥梁，用户可以自由组合文字、按钮、图形、数字等来处理或者监控管理及应付随时可能变化信息的多功能显示屏幕。 随着机械设备的飞速发展，以往的操作界面需由熟练的操作员才能操作，而且操作困难，无法提高工作效率。但是使用人机界面能够明确指示并告知操作员机器设备目前的状况，使操作变的简单生动，并且可以减少操作上的失误，即使新手也可以很轻松的操作整个机器设备。使用人机界面还可以使机器的配线标准化、简单化，同时也能减少PLC控制器所需的I/O点数，降低生产的成本同时由于面板控制的小型化及高性能，相对提高了整套设备的附加价值。
(As a touch-screen interface, is doing between the operator and the two-way bridge between mechanical equipment, the user can freely combine text, buttons, graphics, digital, etc. to handle or deal with monitoring and management and are subject to change information multifunction display screen . With the rapid development of machinery and equipment, the previous user interface needs to be operated by a skilled operator, and operating difficulties to improve work efficiency. However, the use of man-machine interface capable of clear instructions and tell the operator the current status of machinery and equipment, so that the operation becomes simple and vivid, and can reduce operational errors, even a novice can easily operate the entire machinery and equipment. You can also make use of HMI machine wiring standardization and simplification, while also reducing the required PLC controller I/O points, while reducing the cost of production due to the miniaturization and high performance co)
