Diagnostic Timestamp
Diagnostic I/O modules can timestamp the time when a fault occurs or when it
clears. This feature provides greater accuracy and flexibility in running
applications. Modules use the ControlLogix system clock from a local controller
to generate timestamps.
To use diagnostic timestamps, you must choose the appropriate communication
format during initial configuration. For more information, see To c o n f i g ur e
features specific to fast modules, see Chapter 5. on page 134.
