Web-based Management 2:
Diagnostics → Notifications

Valid from firmware release 2025.0 - for earlier firmware see Diagnostics - Notifications

On the Notifications page, any user with access to the WBM 2 can read and download notification logs. Here, the PLCnext Runtime provides a set of built-in notifications and security notifications. In addition users can set up their own notifications (see Notification Logger).

As the default view, the page consists of a table showing recent notifications. The notification table is updated every second. 

  • In the left-most column 1, the severity of each notification is displayed by icons, meaning (in rising order of severity):
    • Internal ()
    • Information
    • Warning
    • Error
    • Critical Error
    • Fatal Error
  • By clicking the  icons in the table header 2, the notifications can be sorted by Severity, Time stamp, Sender name or Name of the notification. The current sorting criterium is the one showing only one icon ( for ascending or  for descending ).  By default, the table is sorted by time stamps in descending order (most recent notifications at the top).
  • By clicking somewhere into a table row, the whole payload (text) of that Notification is shown in the text box below the table 3. If no notification is selected then the text field is empty.
  • In the lower-right section below the table 4 find a button for exporting the shown notifications to a file in the comma-separated value (.csv) format.
  • On top of the table users can open a section with several filter options for the listed notifications by clicking the   triangle in the upper-right corner 5. For details, refer to the Filtering notifications section.

Filtering notifications

Filter options can be applied in parallel or exclusively. At least the maximum number filter is always active.
Note: When editing or adding more filter criteria, the table is reorganized once you click the APPLY FILTER button.

Filtering by severity

For filtering, a cut-off is set, meaning higher levels are included when filtering by a lower level:

  • Filtering on >=Internal displays all notifications because all other security levels are higher.
  • Filtering on >=Information displays notifications from severity levels Information, Warning, Error, Critical Error, and Fatal Error.
  • Filtering on >=Warning displays notifications from severity levels Warning, Error, Critical Error, and Fatal Error.
  • Filtering on >=Error displays notifications from severity levels Error, Critical Error, and Fatal Error.
  • Filtering on >=Critical Error displays notifications from severity levels Critical Error and Fatal Error.
  • Filtering on Fatal Error displays notifications only from severity level Fatal Error because all other security levels are lower.

Filtering by archive name

You can filter notifications by their archive name. You have the following setting options:

  • <All archives> shows notifications from every archive.
  • Selecting one archive name shows notifications from just the selected archive.

Filtering by sender

You can filter notifications by their sender name. Already applied filters form the basis for the Sender drop-down menu: Only the sender names of the notifications already listed in the table are displayed in the Sender drop-down menu.
You have the following options:

  • Select a sender name from the drop-down menu. The listed sender names correspond to the names in the notifications table. 
  • Enter a sender name or a part of a sender name in the input field. Use this option if the sender name has not yet been listed in the notifications table.
    Filtering displays notifications from senders that match (or partially match) the search term you entered.

Filtering by restricting the maximum number of notifications

You can enter the maximum number of notifications to be displayed, regardless of other filter criteria. The default setting is 1024, and the maximum number cannot exceed 4000.

Filtering by timestamp

You can limit the time period for which notifications are displayed by filling in the input fields Time from and/or Time to. When using this filter, entering a date is mandatory; specifying a time is optional. Therefore, if only a time is entered, the date is always set to the current day which then can be edited.

  • Time from set: Notifications that are not older than the specified date (and time) are displayed.
  • Time to set: Notifications that are not newer than the specified (and time) are displayed.

Security logging

For secure operation, user actions in the WBM 2 are logged when working with an active Security Profile (on devices of the first PLCnext Control generation) and always on Secure-by-default devices (e. g., AXC F 1252).

Each session in the WBM 2 is registered under a specific Security Token. The notifications of the User Manager (UM) show the user name and user role along with a unique Security Token for each session.
