How do you establish a remote connection to a server?

  • Entry
  • Associated product(s)


Instructions:
Configure the settings in the server project - as in the procedure given below - in order to establish a remote connection to a server from a client without a client project.

Notes:

  • With "Client without Client Project" we mean a WinCC client that opens the WinCC project directly on the server via an existing Windows network connection (terminal bus). A separate WinCC project is not required on the client. This type of client was designated by default as Client in earlier versions of WinCC (before WinCC V6.0).
     
  • As from WinCC V5.0 there is a new type of client has been added, a client with its own client project (MultiClient). In order to avoid a mix up with the MultiClient the terms "UniClient" and "Standard Client" were used.
     
  • As from WinCC V6.0 the MultiClient is simply called the Client. As from WinCC V6.0 it is not recommended to set up a WinCC server project with the "old" UniClient, but you should rather use the Client (MultiClient). But it is however still possible to use the "Uni Client". This entry refers exclusively to the "UniClient".
No. Procedure
1 Enter and parameterize Client computer in the WinCC computer list
First enter the computer name of the client computer in the computer list of the server project. In the WinCC Explorer right-click the "Computer" item and then in the pop-up menu you select "New Computer...".

Note:
The requirement here is that the WinCC project is created as a multi-user project. With a single-user project you don't have the possibility of adding a new computer to the computer list. In this case you must change the single-user project into a multi-user project.

2 Create a WinCC user for Client operation
Create a user in the "User Administrator" editor who is authorized to use this Client. This user requires "1001 Configure remote" authorization in order to open the server project. If you wish to activate the server project with the same user, the user requires "1000 Activate remote" authorization.

Open the "User Administrator" editor. You can enter the user's name and password via the menu item "User > Create user" and assign the authorizations.

3 Create server package
Create the server package. Ensure that the package generated by you has a double screen as a symbol.


Fig. 03

 

If your package only has a single screen, go to the "Implicit Update" dialog and select the "Automatic Import" check box.
You can find this dialog in the "Server Data" pop-up menu. Right-click the "Server Data" entry in the navigation window and select the "Implicit Update" entry. Now generate your package again.

Notes:
  • Important note for PCS 7 and TIA projects as from WinCC V6:
    In WinCC projects that have been created with the SIMATIC Manager, the pop-up menu of "Server Data" contains neither the menu item "Create ..." nor the menu item "Implicit Update ...".
    How to proceed in this case is described in the WinCC Online Help under the keyword "Create Server Data".
     
  • For UniClients before WinCC V6.0 it was not necessary to create the server package. As from WinCC V6.0 the server package is also required for UniClients in order to display alarms and trends.
4 Link Client to server project
Now you can open the WinCC project from the Client via the network (terminal bus). You have various options for this:
  1. Windows Explorer
    For this, in the Windows Explorer on the WinCC Client you select the server computer via the "Network Environment" entry and switch to the the associated WinCC project directory. Double-click the project file (<Project name>.mcp) to open the WinCC project from the Client. You are also asked for the user name and password. Once you have logged on with a valid user name you can process and activate the project on the Client according to the authorization you have.

    Important:
    You can only open the WinCC project by double-clicking the project file (<Project name>MCP) if WinCC has not yet been started. If the WinCC Explorer is already open, you select the menu command "File > Open..." in the WinCC Explorer. A file selection opens. In this dialog you navigate to the server and select the project file.
     
  2. "SIMATIC Shell" and "WinCC Projects"
    As from WinCC V6.0 SP3 you can use the "SIMATIC Shell" to interconnect, activate or deactivate a WinCC server project "remotely" from the Client. As from WinCC V6.0 SP3  you will find the "SIMATIC Shell" in the Windows Explorer under "My Computer > SIMATIC Shell". In the versions of WinCC before V6.0 SP3 you will find the entry "WinCC Projects" instead of the "SIMATIC Shell" entry.
     
  3. Autostart
    In  Entry ID: 23061262 and Entry ID: 19249315 you will find information about how you can start a WinCC project automatically when the computer boots.

Note:
Before the WinCC project can be opened from the Client, it must first be opened on the server. If the WinCC project is not opened on the server, on the client you get the message "The configured server is not available. Do you want to open the project using the local computer as the server?"
