Identify the data source
Each event needs a clear source: a sensor, reader, controller or operator. Define when it occurs and what data it carries.
Define exchange rules
Agree on data format, identifiers and event time. Consider delays and retransmissions.
Keep the context
A signal without its equipment or operation context has limited value. The database should preserve relationships needed for reporting and analysis.
Test the entire chain
Reading a sensor successfully does not prove the whole automation works. Verify that the event reached the database, was processed once and triggered the intended action.
