Intouch怎样用DASSIDirectwithSiemensS7200PLC通讯

Configu re the S7-200 PLC 1. Start Step7-Micro/Win 32. Create a new project or load your existing one (Figure 1 below): FIGURE 1: STEP 7 - MICRO/WIN32 - PROJECT1 DIALOG BOX 2. Click on Tools and then select Ethernet Wizard. 3. Step through the wizard: FIGURE 2: ETHERNET WIZARD 4. Click Yes when asked to use symbolic addressing. Otherwise the wizard cannot continue: FIGURE 3: CLICK YES 5. Enter the module position of the CP243-1. If you are uncertain about the position, click the button Read Modules. Otherwise you can enter the number directly: FIGURE 4: SPECIFY MODULE POSITION DIALOG BOX 6. Enter the IP configuration of your CP243-1.

Enter the numbers of connections you want to configure for the CP243-1. Default value is 0, which would not allow communication. In this example I will use 2 connections (Figure 6 below): FIGURE 6: 2 CONNECTIONS Now you have to configure the connections. Connection 0 (Figure 7 below) will accept all incoming client requests: FIGURE 7: CONNECTION CONFIGURATION 8. Always select This is a Server Connection.
