Driver Logging can be used to help diagnose abnormal conditions relating to driver activity. Driver logging can also be used for assessing potential problems. The log files that are produced provide useful diagnostic information about specific aspects of the system. For instance, the Points logging option provides diagnostic information about the points on a particular driver.
Should you need to contact Schneider Electric for assistance with resolving a problem that ClearSCADA has detected, you might be asked to provide log files to help in assessing the cause of the problem. 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 common to many simple drivers.
Those driver logging options that are typically required for investigating abnormal conditions are enabled by default. We suggest that the logging 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 any driver logging options that are not listed below, see the driver-specific documentation.
These driver log file options are common to many simple drivers:
- Application—Logs general information about the driver.
- Errors—Logs any errors detected during driver operation. For example, unexpected communications interruptions, or a loss of connection to the ClearSCADA database.
- Point Source—Logs information about the scanner(s) on a driver.
- Server—This option is available for several simple drivers. The option logs information about the channel or server. For example, the assigning of ports, or connection to a remote server.
- Browse Requests—This option is available for several simple drivers. The option logs information about use of some of the browse options on configuration Forms. For example, the Tag browser on a Point Form, and the Comm Port browser on a Channel Form.
- DBServer Requests—Logs information related to requests from users (and so from the server)
- DBServer Calls—Logs information about the low-level interface from driver to server.
