The Power Tool is a client of the OPC I/O Server. The I/O Server maintains the driver's server, group, and item objects and performs all required functions for communicating with the process hardware. The Power Tool accesses the I/O Server and lets you view and modify OPC server, group, and item properties.
The I/O Driver Server Connection dialog box displays when you first start the Power Tool. This dialog box lets you choose whether to set up the Power Tool to communicate with a Local I/O Server (on your computer) or a Remote I/O Server (a computer on the network). If you choose a remote I/O Server, you must enter or select the remote machine name or address.
To connect
to the server on the local machine:
- Start the Power Tool; or, if it is already running, choose OLE Server from the Options menu. The I/O Driver Server Connection dialog box appears.
- Select the Use Local OPC Client Driver option and click Connect.
The Power Tool attempts to connect to the local server. If the connection is successful, the Connection dialog displays the message Connection Established and then the main window of the Power Tool displays. If the connection is not successful, the Connection dialog box displays the message Connection Not Established and you receive the following message:
Connection to the selected server has failed. Do you want to select another server?
- Click Yes if you want to try connecting to a remote server. If you cannot connect to the local server, there is a problem with the server start-up. Refer to Using Event Viewer for details about how to display any errors that the server may have generated.
To connect
to the server on a remote machine:
- Start the Power Tool; or, if it is already running, choose OLE Server from the Options menu. The I/O Driver Server Connection dialog box appears.
- Select the Use Remote OPC Client Driver option and enter the remote machine name or TCP/IP address in the Remote Machine Name or TCP/IP Address box. You must enter the machine name or address exactly. If you do not know the exact machine name, select it using the Network list box.
If the connection is successful, the Connection dialog displays the message Connection Established and then the main window of the Power Tool displays. If the connection is not successful, the Connection dialog box displays the message Connection Not Established and you receive the following message:
Connection to the selected server has failed. Do you want to select another server?
- Click Yes if you want to try another server. If you cannot connect to the machine that the server is on, you may not have an account to that machine or your DCOM settings may be incorrect. Refer to How do I Set up Security for using the I/O Server Remotely for more information.
- Select the Show this Dialog on Startup check box to display the I/O Driver Server Connection dialog box every time you start the Power Tool.
To change the OPC I/O Server connection:
- From the Options menu, choose OLE Server. The I/O Driver Server Connection dialog box appears.
