Return to the front page of this chapter The sixth chapter programming software Six point one 6.1.1 6.1.2 6.1.3 6.1.4 6.1.5 6.1.6 Programming software installation system requirements Software installation hardware connection parameter settings, online contact settings, modify PLC communication parameters Return to the front page of this chapter The sixth chapter programming software 6.1.1 system requirements Operating system: Windows 95, Windows 98, Windows ME or Windows 2000 computer: IBM more than 486 compatible machines, memory more than 8MB, VGA display, at least 50MB hard disk space, Windows support mouse. Communication cable: PC/PPI cable (or using a communication processor card) to connect the computer to the PLC. Return to this section The sixth chapter programming software 6.1.2 software installation STEP 7-Micro/WIN 32 programming software on a CD, the user can be installed according to the following steps: 1. Insert the CD-ROM into the CD-ROM drive. The system automatically enters the installation wizard, or click the "start" button to start the Windows menu. Click the "run" menu. Complete the software installation according to the installation wizard. At the end of the installation, the restart computer options will appear. Return to this section The sixth chapter programming software 6.1.3 hardware connection The communication between personal computer and PLC can be established by using PC/PPI cable. This is the connection between a single host and a personal computer without any other hardware, such as modems and programming devices. Typical single host connections and CPU configurations are shown in Figure 6.1 below. Return to this section The sixth chapter programming software 6.1.4 parameter setting After the software is installed and connected with the hardware, can verify the parameters according to the following steps: (1) in the default STEP 7-Micro/WIN 32 runtime communication or click icon from the menu select the option Communications View, is a communication dialog box appears. (2) double-click the icon of the PC/PPI cable in the dialog box, and the dialog box with the PG/PC interface will appear. See Figure 7.14 in the seventh chapter. (3) click the Properties button, and the interface property dialog box appears, as shown in figure 8.16. Check whether the attributes of the parameters are correct, in which the baud rate default value is 9600 Potter. Return to this section The sixth chapter programming software 6.1.5 online contact The first few steps if successfully completed, it can be established with the SIMATIC S7200 CPU online contact, the steps are as follows: (1) in STEP 7-Micro/WIN 32, click the communication icon, or from the menu select the option Communications View, will be a result of the establishment of communication box, display is connected to the CPU host. (2) double-click the communication to create a refresh icon in the dialog box. STEP 7Micro/WIN 32 checks all the S7-200 CPU stations connected, and creates a CPU icon for each station. (3) double click the station to communicate, in the communication establishment dialog box can display the communication parameters of the selected station. Return to this section The sixth chapter programming software 6.1.6 settings modify PLC communication parameters If you establish an online connection between the computer and the PLC, you can use software to check, set and modify the communication parameters of PLC. The steps are as follows: (1) click the system block icon in the boot bar, or select the System Block option in the View menu from the main menu, The system block dialog will appear. (2) click the Port (s) tab. Check all the parameters and make sure that you click OK to confirm. If you need to modify some parameters, you can modify it first, then click the Apply button, and then click OK to confirm and exit. (3) Click icon in the download tool, can put the modified parameter is downloaded to the PLC host. Return to this section The sixth chapter programming software Six point two function 6.2.1 basic function 6.2.2 appearance 6.2.3 each part function 6.2.4 system configuration Return to the front page of this chapter The sixth chapter programming software Basic functions of 6.2.1 Syntax checking in program editing can avoid errors in syntax and data types in advance. The error checking results of the ladder diagram and the statement table are shown in figure 6.2. The sixth chapter programming software The implementation of software function can be carried out online (online), and the implementation of some functions can also be done offline. On line: a computer or programmer with programming software is connected to the PLC, allowing direct communication between the two. Refer to section first of this chapter for online methods. Offline mode: a computer or programmer with programming software is disconnected from the PLC, which can perform most of the basic functions at this time. Such as programming, compiling and debugging program, system configuration and so on. Return to this section The sixth chapter programming software 6.2.2 appearance Start STEP 7-Micro/WIN 32 programming software, the main interface appearance as shown in figure 6.3. The general interface can be divided into the following areas: (the menu contains 8 main menu items), tools (shortcut buttons), guide (quick operation window), instruction tree (Shortcut window), the output window and window (the user can be respectively or simultaneously open the 5 user window figure in the mouth).
