error indicates that an error occurred when executing the Read Event

History VI. It was probably a problem with the group/tag name.

shutdown indicates that the BridgeVIEW Engine is shutting down. In this

case, the Read Event History VI returns immediately with shutdown

TRUE. You can use shutdown to exit any While Loop that calls the Read

Event History VI.

changed? is TRUE if a new alarm or event was read. If changed? is

FALSE, Read Event History probably timed out before the Event History

Display was updated.
