5、ware and SoftwareStep 1: Creating a Database Using COML S7 (v2.11)The following steps are based on version 2.11 of the Siemens COML S7 software. Wonderware Technical Support recommends that you use the current available version of COML S7 from Siemens.The COML S7 program is used to create the .TXT a
6、nd .LDB files required for Simatic Net to interface a standard Ethernet card to the CP 443-1 TCP module on the S7-400 Universal Rack (UR).Perform the following steps to create the .TXT and .LDB files. 1.Start the COML S7 program; the SIMATIC NET COML S7 dialog boxshould appear as shown in Figure 1.F
7、igure 1. Creating a .TXT file2. Use the following information to create your .TXT file:Node name: Name of the station. Used only for documentation purposes. It has no meaning to the project.Network type: Select TCP/IP from the drop-down list box since the CP installed in the PC is a standard Etherne
8、t card.Name: Enter a meaningful connection name (maximum 32 characters). This connection name will appear again when you create topics in the S7 I/O Server.VFD name: This VFD name is used by an application to specify which S7 connection to use. The Virtual Field Device (VFD) name is used duringthe t
9、opic configuration in the I/O Server.Remote addr.: This is the IP address of the CP 443-1 TCP to connect to on the S7-400 UR. It should match the IP address defined in Step7 programming software.Local TSAP: The Transport Service Access Point (TSAP) is the layer 4 address. The first two digits specif
10、y the device. The last two digits must bezero. Wonderware Technical Support recommends a setting of 01.00Remote TSAP: This address consists of two parts:o group: specification of the device: 01 = PG, 02 = OS, 03 = others o group: addresses of the SIMATIC components: (Bit 0.2) = Rack (Subsystem), (Bi
11、t 3.7) = Plug in portWonderware Technical Support recommends a setting of 03.0x, where x = slot of the CPU (not the CP). Since the CPU is normally installed next to the power supply (which takes 2 slots), the usual setting here is 03.033.When completed, save the .TXT file under File/Save Text Databa

13、rface (v5.0), Software1.Start the Setting the PG/PC Interface program. From the Access point of application drop-down list box, select S7ONLINE (STEP 7) as shown in Figure 4.Figure 4. Setting the PG/PC Interface (V5.0)2.From the Interface parameter set used list box, highlight TCP/IP - (Adapter Type
14、) and click on Properties.Note In this example, TCP/IP - (Adapter Type) appears under the Interface parameter set used list box; however, this will not be the case when you are initially setting up. To install the TCP/IP under the Install button, consult your Siemens documentation. 3.In the Properti
15、es dialog box, click on the S7-Protocol tab. Click on the Search button and select the directory where the .TXT and .LDB files were saved in COML S7. When complete, click OK.Figure 5. Configuring ISO Interface4. Once the SAPI-S7 Database path points to the .LDB file, click the TCP/IP Network tab and
16、 then click the Network Options button, as shown in Figure 6.Figure 6. TCP/IP Dialog Box5.In the Network dialog box , click the Protocols tab . Under the Network Protocols section, highlight TCP/IP Protocol, then click OK, as shown in Figure 7.Figure 7. Defining Network Protocols6.You will be return
17、ed to the Setting the PG/PC Interface (V5.0) dialog box with the TCP/IP - (Adapter Type) highlighted, click OK. 7.When complete, the following Warning dialog box will appear stating that the access path has changed. Click OK.Figure 8. Warning Message8. You will then be prompted to restart the parame
18、ter settings, click OK.Step 3: Verifying the TCP/IP InterfaceFollow these steps to test that the Ethernet card, with the Simatic Net Software, can interface via the TCP/IP interface. 1.In the Setting the PG/PC Interface (V5.0) dialog box, highlight TCP/IP - (Adapter Type) and click the Diagnostics b
19、utton. 2.In the Diagnostics dialog box, click the SR Protocol tab. Under the SR Status section, click the Test button. If correctly interfaced, you should see the results as shown in Figure 9.Figure 9. Verifying the InterfaceAccessing/Configuring the CP 443-1 TCP ModuleThe CP 443-1 TCP module should
20、 be configured with a standard profile. If this has not been done, create an S7 project that matches your S7 hardware configuration.Note If you require assistance in creating an S7 project, consult Siemens S7 documentation or contact Siemens Technical Support or a Siemens distributor.Perform the fol
21、lowing steps to access the CP 443-1 TCP module using Simatic Manager Step 7 (v5.0 + Service Pack 1) andStep 7 S7/M7 Hardware Configuration (v5.0 + Service Pack 1). 1.Open-up the S7 project, SIMATIC Manager S7-400 window, and double-click on Hardware, as shown in Figure 10.Figure 10.
