Driver Logging Options that are Specific to the OPC UA Driver

This section is intended for use by system administrators and high-level engineers who need to use statistical and diagnostic information to assess the state of the Geo SCADA Expert system. This section contains information that is specific to this particular driver.

Driver logging is useful for investigating driver abnormal conditions or potential abnormal conditions. It provides useful diagnostic information for specific aspects of the system. For instance, the Points logging option provides diagnostic information for the points on a particular driver.

Should you need to contact Schneider Electric for assistance to resolve an abnormal condition on your system, you might be asked to provide Log files to help in assessing the cause of the abnormal condition. Be aware that existing warranty and support arrangements determine the level of help that you receive should you need to contact Schneider Electric.

This section explains the driver logging options that are specific to this particular driver.

Those driver logging options that are typically required for investigating driver abnormal conditions are enabled by default. We recommend that the options are left at this default unless other logging options are specifically requested by Schneider Electric, or the default options are adversely affecting system performance.

For information on log files and defining the log file settings, see Driver Logging in the Geo SCADA Expert Guide to Server Administration.

For information on the driver logging options that are available for many advanced drivers, see Common Advanced Driver Log File Options in the Geo SCADA Expert Guide to Advanced Drivers.
