HMI是人机界面的简写，它为PLC控制系统、I/O或者其他控制系统提供一个人性化的操作界面，而人机界面则通过RS232、485、MODBUS、CAN总线等协议与这些控制系统交互数据与控制信号。由于这种交互是实时的，这就使得HMI(人机界面)实现了下面的关键功能：
1、实时监控PLC、I/O的运行，并在HMI上形象地显示出来;
2、操作者可以通过HMI向自动化设备发出控制信号，使得自动化设备可以按照操纵者的意图运行。
人机界面(HMI)的应用域决定了它必须具备下列特性：
1. 人机界面(HMI)必须具备和各种自控设备交互数据的能力，这需要HMI集成各种型号的PLC、I/O、各种总线协议等自控设备的通信协议;
2. 人机界面(HMI)应该提供一个工具软件，供客户开发基于特定控制系统定制相应的应用;
3. 人机界面(HMI)必须是工业的产品，能够适应工业应用环境，具有可靠的质量和的性能。
