STEP 7 编程软件的使用方法（国外英文资料） 4.1.1 STEP 7 overview STEP 7 is used for programming, monitoring and parameter Settings for S7, M7, C7, and WinAC. The textbook is based on STEP 7 V5.2. STEP 7 has the following functions: hardware configuration and parameter Settings, communication configuration, programming, test, boot and maintenance, file build, run, and diagnostic functions. 4.1.2 STEP 7 hardware interface PC/MPI adapter + rs-232c communication cable. The computers communication card CP, 5611 (PCI card), CP 5511, or CP 5512 (PCMCIA card) connects the computer to the MPI or PROFIBUS network. Computer industry Ethernet card CP 1512 (PCMCIA card) or CP 1612 (PCI card). The authorization of STEP 7 is in the floppy disk. Program AuthorsW on the STEP 7 cd-rom is used to display, install, and remove authorization. 4.1.4 STEP 7 programming function 1.
