MESSAGES: Error List, Logging and Desktop Notifications/Alerts
Messages reported by the system are output in the MESSAGES window (located in the Cross Function Area), or they are displayed as desktop notifications/alerts.
 MESSAGES | You can hide/show the window by clicking the button shown left on the Cross Function Area toolbar. For closing the window, you can also click the cross icon on the right of the window title bar:  |
 | If at least one new element is added to the window while it is closed, the icon on the Cross Function Area toolbar is shown with an envelope icon. |

The MESSAGES window provides several categories which can be activated via the corresponding button in the window toolbar. The categories can be combined to show several outputs.
This topic contains the following sections:
Error List
The Error List displays errors, warnings and information messages concerning the current project and which can be resolved by the user. Mainly these are compiler/parser errors and warnings that appear during programming (continuous background check) as well as, for example, invalid IP settings.
Automatic background compilation: While editing the project, the compiler is automatically executed after a modification. This way, detected errors are reported without a manual compiler start. The error list in the message window is only updated after completing the compilation.
| Note
By default, all warnings are shown in the MESSAGES window. You can hide specific warnings in the window by editing the 'Compiler | Warnings Settings' category in the 'Extras > Options' dialog. All warnings for which the 'Hide' checkbox is activated will not be shown in the MESSAGES window (and also not be counted in the build result (number or errors and warnings) displayed in the status bar). You can ignore the 'Hide' setting of a warning configured in the 'Compiler | Warnings Settings' category by activating the 'Show hidden' filter in the MESSAGES window (see the procedure below). |
Logs
Several logs can be used to track the system activities. These logs are saved persistently with the project and the messages are restored when opening the project (as long as they are not resolved). The log to be displayed can be selected in the MESSAGES window toolbar.
An incoming new message in a log which is not visible, is indicated with the + icon: 
The context menu in the logs provides access to all the functions available for the logs. It allows you, for example, to export the log entries to an *.csv file, delete entries of a specific log or of all logs, etc. (see below for a description of the various functions).
| Log type | Message type |
|---|---|
| Project Log | Stores messages on tool- and project related events and events concerning the engineering environment. It logs, for example, errors during import of gsdml or fdcml files, or information on the last PLCopen XML import (see topic "Importing Types (POUs, Data Types)  ‣ Importing Types from Another Project
×‣ Importing Types from PLCopen XML ×‣ Importing Types from IEC 61131-10 XML ×"). It, however, only considers standard (non-safety-related) events. |
| Online Log | Stores messages from the standard (non-safety-related) runtime (eCLR error catalog) and other errors/warnings concerning the online communication with the standard controller and the Safety PLC. |
| Import Export log | Shows the messages of all import and export operations with the exception of the messages for importing from another project. |
| Safety Log | Stores any editing operations and messages that relate to safety-related project parts. Refer to the section "Safety Log" in the topic "Safety-Related Application" for details. |
| Compare Log | Compare shows the detected differences after performing a project comparison. |
Desktop notifications/alerts
PLCnext Engineer creates notifications in some cases, for example, to inform about build steps/results or successful/failed engineering events.
There are three types of notifications: information, warnings, errors. The severity of these types is indicated by the border color and a corresponding icon.- Notifications which are shown in the upper right corner of the screen.
These notifications are non-modal, i.e., they can remain visible while PLCnext Engineer can continue to be operated and they disappear automatically after a few seconds. You can close the notification by clicking the x icon and browse through the messages by clicking '<' and '>'.Double-clicking a notification jumps to the cause of the message if a jump target is available. - Notifications and alerts which are shown in the center of the screen.
These are modal, i.e., PLCnext Engineer cannot be operated any further until the current message has been confirmed.
