[Debug]DriverTrace

UNINTENDED EQUIPMENT OPERATION

Do not change the [Debug]DebugDriverTrace parameter in the citect.ini file, except on the advice of Technical Support for this product.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

The DriverTrace utility is an extension of the CitectSCADA Kernel that can be used to display the commands and information being issued to a driver by CitectSCADA. It can be useful in debugging a driver, for example, it can help determine why a driver is unable to fully initialize.

Allowable Values:

OFF - Turns the DriverTrace off.
CMDS - Turns the DriverTrace on, but does not display the contents of the data buffer associated with the command. Be aware that specific driver commands need to be enabled with the DriverTraceMask INI parameter (or associated Kernel command).
VER - Turns the DriverTrace on, and includes the contents of the data buffer in the display. Be aware that specific driver commands need to be enabled with the DriverTraceMask INI parameter (or associated Kernel command).
ERR - Turns the DriverTrace on, but only traces DCBs with errors. (DCBs are the internal data structures used for communication between the I/O server and a driver.)

Default Value: OFF

Note: You can adjust this parameter during runtime using the SetLogging() function. For more information, search the CitectSCADA Help for the topic Adjusting Logging During Runtime. To access the Help, select Citect Help Topics from the Help menu in Citect Explorer or Project Editor.
