[VC/MFC] ModBus DL : 0: Modbus协议是应用于电子控制器上的一种通用语言。通过此协议，控制器相互之间、控制器经由网络（例如以太网）和其它设备之间可以通信。它已经成为一种通用工业标准。有了它，不同厂商生产的控制设备可以连成工业网络，进行集中监控。此协议定义了一个控制器能认识使用的消息结构，而不管它们是经过何种网络进行通信的。它描述了一个控制器请求访问其它设备的过程，如何回应来自其它设备的请求，以及怎样侦测错误并记录。它制定了消息域格局和内容的公共格式。当在同一Modbus网络上通信时，此协议决定了每个控制器需要知道它们的设备地址，识别按地址发来的消息，决定要产生何种行动。如果需要回应，控制器将生成反馈信息并用Modbus协议发出。在其它网络上，包含了Modbus协议的消息转换为在此网络上使用的帧或包结构。这种转换也扩展了根据具体的网络解决节地址、路由路径及错误检测的方法。此协议支持传统的RS-232、RS-422、RS-485和以太网设备。许多工业设备，包括PLC，DCS，智能仪表等都在使用Modbus协议作为他们之间的通信标准。-The Modbus protocol is a common language applied to electronic controllers. Through this protocol, the controllers communicate with each other, and the controller can communicate with each other via a network (such as Ethernet) and other devices. It has become a common industry standard. With it, different manufacturers of control equipment can be connected into an industrial network, for centralized monitoring. This protocol defines a message structure in which a controller can recognize the use of the message, regardless of the network through which it is communicating. It describes how a controller requests access to other devices, how to respond to requests other devices, and how to detect errors and record. It sets the public format of the message field pattern and content. When communicating on the same Modbus network, this protocol determines how each controller needs to know their device address, identifies messages sent by address, and determines what action to take.
