You can view the PLC log in this tab. It lists the events that were recorded on the target system. This concerns:

  • Events during the startup and shutdown of the system (components loaded, with version)

  • Application download and loading of the boot application

  • Custom entries

  • Log entries from I/O drivers

  • Log entries from data sources

Offline logging

_cds_icon_option_deactivated: Default settings

_cds_icon_option_activated: The PLC also records actions that are not related to the connection with the controller.

UTC time

_cds_icon_option_deactivated: Standard setting; the time stamp is converted to the local time on the computer as indicated by the time zone of the operating system.

_cds_icon_option_activated: The time stamp of the runtime system is displayed.

Severity

There are four categories for the severity of the event:

  • _cds_icon_info: Message

  • _cds_icon_warning: Warning

  • _cds_icon_error: Error

  • _cds_icon_debug: Debugging

You can show or hide each category with the help of the corresponding button in the bar above the list. Each button shows the number of log entries of the category concerned.
