OPC Server Setup Tags
Note: Use of the OPC Server Setup tag is restricted to VTS installations that include this feature as part of the license key. You can confirm whether this feature is enabled by opening the About VTS dialog from the VTS Application Manager.
Server Name: Trihedral.VTSOPC.DA
The OPC Server Setup tag is used to turn your application into an OPC Server. Minimal VTS configuration is required on your part to do this.
The VTS OPC Server supports the OPC DA (Data Access) Standard.
Note: OPC security is handled by Windows via user and group security permissions set using the Microsoft Component Services dialog and the COM Security tag of the My Computer dialog. Please refer to Securing an OPC Server for more information on OPC security.
Only one OPC server may be defined per application. Attempting to define a second server in the same application will result in an error dialog stating "An application can have at most one OPC Server Setup tag".
Note: Use of the same namespace for more than one application is strongly discouraged as it will cause significant problems.
There are no drawing methods for this tag. When the OPC Server Setup tag has been created, the application’s OPC-supporting tags become available on the VTS OPC server.
For technical information about the OPC Server configuration in VTS, please refer to the chapter: Data Sharing.
