RTU（Remote Terminal Unit）是一种远端测控单元装置，负责对现场信号、工业设备的监测和控制。与常用的可编程控制器PLC相比，RTU通常要具有优良的通讯能力和更大的存储容量，适用于更恶劣的温度和湿度环境，提供更多的计算功能。正是由于RTU完善的功能，使得RTU产品在SCADA系统中得到了大量的应用。-RTU (Remote Terminal Unit) is a remote device monitoring and control unit is responsible for on-site signals, industrial equipment monitoring and control. With the commonly used programmable logic controller PLC compared, RTU usually have excellent communication capabilities and greater storage capacity for even worse temperature and humidity environment, provide more computing power. It is perfect RTU functions, making RTU Product in the SCADA system has been a large number of applications.
