You can configure a driver to start automatically by adding the I/O Control program to the list of programs that are defined in the System Configuration Utility (SCU) to start automatically. FIX or iFIX may have already added this program to the list if you had one or more drivers installed when you installed iFIX. However, if you do not have any drivers installed, or I/O Control is not listed, add the program to the Configured Tasks list in the SCU.

IMPORTANT: You must install the OPC Client in your root iFIX or Dynamics directory to start it automatically from the SCU. If you have not installed the driver in this directory, uninstall it and then re-install it in the proper path.

To set the I/O driver for automatic startup:

1. Start the System Configuration Utility (SCU):
1. From the Start menu, choose Programs.
2. From the Programs menu, choose Dynamics or iFIX.
3. Choose System Configuration from the menu that appears.
2. From the Configure menu, choose Tasks.
3. In the Filename box, enter the Base path and IOCNTRL.EXE.
4. Enter the following command lines as needed, separated by a space:

5. Select Background and click Add.

If you are connecting items to one or more database blocks and need to access data with SAC, add the OPC Client to the SCADA Configuration dialog box as follows.

To add the OPC Client to the SCADA Configuration dialog box:

1. From the Configure menu, choose SCADA.
2. Click the ? button next to the I/O Driver Name box.
3. Select the OPC Client from the dialog box and click OK. The following text appears in the I/O Driver Name box:

OPC - OLE for Process Control Client 7.x

4. Click Add to add the selected I/O driver to the Configured I/O Drivers list box.

NOTES:

• You must have an OPC Client configuration file in your root iFIX or Dynamics directory with the name nodename.OPC. This file is necessary for iFIX to load the driver and is created by the installation program when you install the OPC Client driver. You also need a configuration file with a different name that defines your servers, groups, and items.
• If you are using iFIX, nodename.OPC resides in your Database path (C:FIX32PDB, by default). Do not move, rename, or delete this file. iFIX uses the file to load the driver. Use nodename.OPC to define your servers, groups, and items.
• If you subsequently change the name of your SCADA server after installing the OPC Client driver, iFIX cannot automatically start the driver because the name of the node does not match the name of the configuration file. To correct this, rename the configuration file to match the name of your SCADA server. For example, if you change the name of the SCADA server from SCADA1 to SCADA9, rename the configuration file from SCADA1.OPC to SCADA9.OPC.
