Logging

You can activate a log file in the server for extended diagnostics, in which various information is then recorded on the basis of different log levels.

Influence of logging on the operating behavior Please note that enabling the log file can have a negative impact on the speed and operating behavior of the TwinCAT OPC UA Server.

The default path for the log files created depends on the operating system used and is described in more detail in the chapter Application directories.

Logging is usually enabled/disabled via the TwinCAT OPC UA Configurator. You can enable/disable logging both online on the server and offline using the corresponding configuration file, which means that logging is only enabled after a server restart. The following screenshot shows the configuration interface for online logging:
