Output diagnostic messaging

Studio generates local diagnostic messages. Your local project running in Studio generates diagnostic messages independently of the project running on the server. These local messages are displayed only in the local Output tab.
Note: Output diagnostic messages, are not reported to Server, and are not logged. These are local messages only.
Examples of messages
The output diagnostic messages are usually current status messages, such as:
-
Connection has been opened
-
Project was validated successfully
-
Compile completed successfully
-
Project saved
Output tab
The Output tab at the bottom of the screen displays messages that enable you to monitor and diagnose the condition of your project from within Studio. Only the messages that AVEVA™ Production Management has generated since you last opened your project display in the currently running instance of Studio.

Right-click the diagnostic window and click Clear All.
TraceLevel property
With the exception of the project root item, if you change the TraceLevel property of any item in the running local project, save the project to the server.

Until you save any changes, Production Analyst generates local diagnostic messages with the use of the modified TraceLevel setting of the item, and you receive server diagnostic messages in the unmodified TraceLevel setting. Therefore, the messages that display in the Output window for an item are not the same level as those displayed in the Server Diagnostics window for the same item.
