Starting I/O Drivers Automatically

I/O drivers are started by the I/O Control program through the Task Configuration dialog box. When you install an I/O driver, the I/O Control program is automatically added to the list of tasks.

If you remove the I/O Control program from the task list, you can add it back again. The table below shows you the command line parameters you can use to specify how I/O drivers start.

I/O Control Command Line Parameters
Parameter	Description
/A	Starts all I/O drivers identified in the SCADA configuration.
/Sxxx	Starts one I/O driver, where xxx is the three letter I/O driver acronym. For example, /SABH.
/Dxxx	Delays the startup of a driver where xxx is the delay time in seconds.
/APxxx	Sets the message rate for all drivers, where xxx is a value of 1 to 100.
/SdrvPxxx	Sets a specific driver's message rate, where xxx is a value of 1 to 100.

NOTE: FIX I/O drivers 7.x or greater automatically start communicating with their OPC server. No command line parameter is needed.
