Notifications registered by the PLCnext Runtime System
The following tables show the notifications that are predefined in the PLCnext Runtime System and will be issued by the PLCnext Runtime System.
Note: For security-related notifications with firmware 2022.0 LTS or newer, see Security notifications of PLCnext Runtime.
Compatibility
The SenderName declarations have changed over time. With firmware 2020.6 they have been consolidated and will now stay this way.
Due to breaking changes with firmware 2022.0 LTS in the structure of notification archives, downgrading to a former firmware release causes an exception.
Remedy:
- Reset the device to Default setting Type 1 (see Factory Reset).
↪ Existing notification archives will be closed and renamed.
↪ An archive with appropriate structure for the firmware is generated, with a first notification in it which points to the renamed archive from firmware 2022.0 LTS.
Severity levels
In the Notifications WBM page (up to firmware 2024.6), these icons are displayed for the different severity levels:
Internal
Information
Warning
Error
Critical
Fatal
In the Notifications WBM 2 page (from firmware 2025.0), these icons are displayed for the different severity levels:
Internal
Information
Warning
Urgent (warning)
Error
Critical (error)
Fatal (error)
Note: From firmware version 2023.6 on, notifications with the severity
Internal are no longer logged.Notifications by SenderName
The notifications in the following sections are grouped by their SenderName and ordered by their NotificationName. Newest entries are marked green in the Availability column.
Alarms
These Notifications are only shown here, because they are used internally by the implementation. These notifications are not intended to be used or sent directly. Instead, the designated methods of the AlarmServer should be used. It is recommended to read the Alarms description before working with these notifications.
From firmware version 2023.6 alarm notifications (Arp.Services.Alarms.Log.*) are logged into a separate archive alarms (file: /opt/plcnext/projects/Default/Services/NotificationLogger/alarms.config).
Note: If the notification is generated by the embedded OPC UA® Server then the
NotificationName ends with .eUAServer. If generated by a function block then the NotificationName ends with .eCLR.| NotificationName ↓ | Severity | PayloadTypeName | Availability |
