摘　　要：西门子设备有多种不同的现场总线协议,如MPI、PROFIBUS、PROFINET等。S7协议是西门子S7系列产品间通讯使用的标准协议,优点是无论通信双方是在同一MPI总线上、PROFIBUS总线上或者同一PROFINET总线上,都可以通过S7协议建立通信连接。本文针对西门子LOGO! PLC和840Dsl数控系统的应用,详细描述如何通过建立单边通讯实现两台设备的数据交换。Siemens equipment has a variety of different fieldbus protocols, such as: MPI, Profibus, Profinet,etc. The S7 protocol is a standard protocol used for communication between Siemens S7 series products. The advantage is that no matter whether the communication parties are on the same MPI bus, Profibus bus or the same Profinet bus, the communication connection can be established through the S7 protocol. Aiming at the application of Siemens LOGO!, PLC and 840Dsl CNC system, the way to realize the data exchange between the two devices by establishing unilateral communication has been described in detail in the test.
