Working with Servers and Groups for the OPC Client Driver

Selecting a server and a group | Adding servers or groups to the driver | Viewing server properties

To select a server and a group:

  1. Select the OPC client driver you want to add the database tags to and click Next. The OPC Client - Group Selection page appears.
  2. From the list of servers, expand the server with the group you want and select the desired group.

If the server or group information you want is not available, refer to the procedures To add an OPC group and To add or change a server or group using the Power Tool.

  1. Click OK. The server, group, and item information is added to the I/O Address field in the target application section of the spreadsheet for the selected items.

NOTE: The Driver Wizard does not automatically generate an I/O address for a tag with a blank Fully Qualified Item ID field in the Discovery Agent section of the spreadsheet. If you selected one of these tags to add to iFIX, the I/O Address field remains blank, or contains the ServerX.GroupY name only when the Driver Wizard completes. You can double-click the I/O Address field and manually enter an I/O address before or after adding the tag to iFIX or you can enter an I/O address directly in Database Manager after the tag has been added to iFIX.

To add a server or group to the OPC Client driver:

  1. If the server or group you want is not available, click the Run OPC Power Tool button. The I/O Driver Server Connection dialog box appears, allowing you to connect to the OPC Client Driver Power Tool.

IMPORTANT: Make sure you connect to the locally installed OPC Client driver. If you connect to a remote driver, the changes you make to its configuration file will not display in the OPC Client- Group Selection page.

  1. In the Power Tool, add the required server and/or group information and save your changes. For more information about adding servers and groups, refer to the OPC Client Driver online help.
  2. On the OPC Driver - Group Selection page of the Driver Wizard, click the Refresh button to refresh the list of servers and groups. Your changes now appear in the list.

To view server properties

  • On the OPC Driver - Group Selection page, select the server you want to view and click View Properties. The iFIX OPC Client Server Properties dialog box appears.

NOTE: If you need to make changes to the server properties, see To add or change a server or group using the Power Tool.
