Explanation: Event logging is the process of recording events from the industrial process, storing them for later analysis, and triggering an alarm in case of a specific event. This feature allows the PLC to record important events, such as alarms, operator actions, and machine status, and store them for later analysis. This feature is particularly useful for troubleshooting and identifying the root cause of problems.
