 Route errors that require immediate action to the FactoryTalk Diagnostics List, and to
the local log.
At run time, if the FactoryTalk Diagnostics List is visible, an operator can alert the
plant’s control systems engineer to problems such as tag errors, as they occur.
During scheduled maintenance time, the engineer can use the errors, together with
warning or information messages recorded in the local log, to analyze operation of the
system and make the necessary corrections.
For more information, see “Setting up message routing” on page 15-5.
Message categories
FactoryTalk Diagnostics messages are categorized by severity and audience.
To route messages, you specify a destination for messages of a particular severity and
audience. For example, you can specify the FactoryTalk Diagnostics List as the
destination for Errors that have Operator as the audience.
Message severity
FactoryTalk View SE uses four message severities:
 Errors indicate that a process or action has failed. For example, an error might
indicate that a tag’s value could not be written, or an ActiveX object is missing.
 Warnings indicate that a process or action might not function correctly, or might
eventually fail if preventive action is not taken.
For example, if an ActiveX object in a graphic display is a different version than the
one installed at the FactoryTalk View SE Client, a warning is logged to indicate the
mismatch. Mismatched ActiveX controls might not behave as expected at run time.
 Information messages indicate that a process or action has completed successfully.
For example, an information message is logged when a user logs on to the system.
 Audit messages indicate that the system configuration has been changed.
Message audience
FactoryTalk View SE uses three message audiences: Operator, Engineer, and Developer.
You cannot change the audience or the severity categories assigned to Diagnostics messages.
For example, you cannot specify that a Developer receive all messages of the Error type.
FactoryTalk View SE records an Audit message for all tag writes, and whenever a component
is added, removed, or deleted from a multi-component editor, such as the Data Log Models,
Graphics, or Macros editor.
