1、Intouch 怎样用DASSIDirect with Siemens S7200 PLC 通讯Configure the S7-200 PLC1.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 Box2.Click on Tools and then select Ethernet Wizard.3.Step through the wizard:Figure 2:

2、 Ethernet Wizard4.Click Yes when asked to use symbolic addressing. Otherwise the wizard cannot continue:Figure 3: Click Yes5.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: Specif

3、y Module Position Dialog Box6.Enter the IP configuration of your CP243-1. Especially during the startup phase of the project, I would recommend not to use a BOOTP server. Let the module detect the connection type (Figure 5 below):Figure 5: Module Address Configuration7.Enter the numbers of connectio

4、ns 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 ConnectionsNow you have to configure the connections. Connection 0 (Figure 7 below) will accept all incoming client requests:Figure

5、 7: Connection Configuration8.Always select This is a Server Connection. I recommend using the default TSAPs as suggested by Step7-Micro/Win32. 9.Click Next Connection (or Prev. Connection if available) to step through all the connections to configure them.Note: If you plan to use such a connection,

6、 be sure that only one client tries to connect to the PLC via this connection at the same time. All other connection tries will be rejected.Connection 1 accepts only requests from the specified client:Figure 8: Specified Client Requests10.If all connections are configured click OK.During the startup

7、 phase of a project I would recommend not to use a CRC protection:Figure 9: No CRC ProtectionThe wizard now needs a range in the V-Memory where to store this information. Step7-Micro/Win32 will suggest a valid range. 11.Click on Suggest Address if you have planned to use this range for something els

8、e. In this case Step7-Micro/Win32 will suggest another free range that has the correct size to hold this data:Figure 10: Store Memory Allocation for Address 12.Click Next.The program now has enough information:Figure 11: Generate Project Components13.Click Finish to complete the configuration:Figure

9、 12: Complete the Wizard Configuration14.Click Yes.In Step7-Micro/Win32 you should now see something like the following figure:Figure 13: Step7_Micro/Win32 WindowStep7-Micro/Win32 has created some new entries in the V-Memory, starting at the address as specified during the setup of the CP243-1.15.Do

10、wnload the configuration to the PLC:Figure 14: Download the Configuration16.Select all options and click OK (Figure 15 below):Figure 15: Download Options17.Set the PLC to STOP mode in order to be able to download a new configuration:Figure 16: PLC STOP Mode18.After the download dont forget to set th

11、e PLC to RUN mode again. This will not be done automatically:Figure 17: PLC RUN Mode The PLC side is now configured.Configure the DAServerConfiguration of the DAServer is quite easy. Since we have created two connections in the PLC, we will also create two connections in DASSIDirect DAServer.Connect

12、ion 0 will correspond to the connection as Figure 18: DASSIDirect Connection 0The Remote TSAP in DASSIDirect must be the Local TSAP in the PLC configuration, and vice versa.Connection 1 shown in Figure 19 (below) will correspond to the connection as created in Figure 19: DASSIDirect Connection 1Now

13、create your device group(s), if necessary. For a DDE/SuiteLink connection you need to have at least one device group per connection, for OPC it is not necessary. For to test the communication as described below, please enter a device group called S7200.The connection between DASSIDirect and the S7-2

14、00 PLC should now be ready to test.Test the CommunicationIn previous TechNotes we used wwclient for testing. This tool will no longer be installed when installing ArchestrA (A) products like InTouch 8.0 or any DAServer. If you have InTouch 7.11 installed you will find this tool under Program Files/W

15、onderware FactorySuite/Common and you can use this tool.1.Create a simple InTouch application with one tag. 2.Select Special/Access Names from the main menu. 3.Select Add.The Add Access Name dialog box appears:Figure 21: Add Access Name4.Enter a meaningful name in the Access field. 5.Leave the Node

16、Name blank if you have InTouch and DASSIDirect on the same node. Otherwise enter the nodename of the PC where DASSIDirect resides. The Topic Name must match the Device Group name as configured in DASSIDirect.6.Select Special/Tagname Dictionary and select New.Figure 22: New Tagname7.Select Type: I/O

17、Integer and the access name as created in the previous steps. 8.Use the item MB1 because it always exists in all S7-200 PLCs.Use this tag in the window you just created.9.Activate DASSIDirect in the System Management Console (SMC). 10.Start WindowViewer. 11.Open the Diagnostic in the SMC to verify the communication:Figure 23: Check Communication from the SMCIf you see a Time value that is changing, and a Client Quality of 00C0, your communication is fine.
