标准MODBUS规约文档。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。它已经成为一通用工业标准。(Standard MODBUS Statute of the document. Modbus protocol is applied to an electronic controller on the lingua franca. With this agreement, the controller between the controller via the network (such as Ethernet) and other devices can communicate. It has become a common industry standard.)
