PARKER派克气缸GDC50-300 3/8提高监控和访问对话频率。重要性原则即按照管理对象在控制系统中的重要性和全局性水平，设计人机界面的主次菜单和对话窗口的位置和突显性，从而有助于管理人员把握好控制系统的主次，实施好控制决策的顺序，实现调度和管理。面向对象原则即按照操作人员的身份特征和工作性质，设计与之相适应和友好的人机界面。根据其工作需要，宜以弹出式窗口显示提示、引导和帮助信息，从而提高用户的交互水平和效率。人机交互界面，无论是面向现场控制器还是面向上位监控管理，两者是有密切内在联系的，他们监控和管理的现场设各对象是相同的，因此许多现场设备参数在他们之间是共享和相互传递的。人机界面的标准化设计应是未来的发展方向，因为它确实体现了易憧、简单、实用的基木原则。
