摘要
西门子S7-300／400系列PLC的编程软件STEP7-SIMATICManager中包含了多种高级编程方式，为实现复杂的控制功能提供了保证。本文以ANY参数类型为主，结合PROFIBUS-DP主从数据通讯的案例，阐述了如何构造ANY类型的参数变量，并最终实现模块化编程。
The various advanced programming modes are included in the programming software STEP7-SIMATIC Manager of Siemens S7-300/400 series PLC, which provide a guarantee for achieving the complex control functions. By taking the parameter type ANY as the main and combining with the example of Profibus-DP Master-slave data communication, this paper elaborates how to construct a parameter variable of the type ANY, and finally realize the modular programming.
