How the term is used
A central maintenance system can provide fault history, present-leg messages, initiated tests, configuration data and maintenance pages. Names and architecture vary by manufacturer.
Where you may encounter it
Maintenance teams use the system to collect evidence before entering approved fault-isolation procedures.
A central message is not a maintenance instruction and does not automatically identify the failed component.
