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。

The MM-IM is mains-powered and acts as a single point for site supervisory control and data acquisition of up to 4000 points. With integrated IEC61131 programming suite of language, the MM-IM is an Outstation RTU (Remote Terminal Unit) and Programmable Logic Controller (PLC) in …

The MM3PEx RTU is an intrinsically safe version of the popular Battery MM3P with all the same powerful features such as long battery life, full telemetry features and simplicity of installation. It provides the best of both worlds; a 'logger's' compact form and simplicity of installation with the rich functionality of a high performance

the MM-IM is an RTU and PLC in one box. Its wide range of interfaces and protocols enables integration with any typical site equipment, from PLCs to smart sensors.

2025年1月4日 · Modbus RTU协议（Modbus Remote Terminal Unit） 是一种常用于工业自动化领域的串行通信协议，尤其用于监控和控制设备之间的数据交换。它基于主从（Master-Slave）模式，主要应用于通过串行通信接口（如RS-232、RS-485等）连接PLC（可编程逻辑控制器）、传感器、仪表等设备。
