4 BASIC FUNCTIONS
4.12 RAS Function
■
File creation timing
An event history file is created when:
• When the power is turned OFF and ON (no event history file exists/after the change of event history settings)
• When a C Controller module is reset (no event history file exists/after the change of event history settings)
• At initialization of memory
• At registration of event history (no event history file exists)
When a new event history file is created, the event that indicates a new file creation is saved.
The following shows the operations of the event history when the storage memory is an SD memory card.
■
Parameter application timing
The changed parameters are enabled at any of the following timing.
• When the power is turned OFF and ON
• When the C Controller module is reset
If the C Controller module operating status is changed from STOP to RUN after writing the changed
parameters, the changed parameters will not be enabled. The changed parameters are enabled only after
turning the power OFF and ON, or resetting the C Controller module.
Event dropping
If the event are detected frequently, some events may be dropped. In this case, the event code (*HST LOSS*) which indicates
that the event is dropped is displayed.
If the power is turned OFF or the C Controller module is reset while sampling event history, the status of the
source module will be unknown. Therefore, the event code (*HST LOSS*) may be displayed and the source
module is not displayed.
Displaying event history
The event history can be displayed using the menus of CW Configurator. For details on the operating procedures and how to
read the displayed information, refer to the following manual.
CW Configurator Operating Manual
Clearing event history
The event history can be cleared on the event history window. Once the event history is cleared, all the event history stored in
the specified storage memory is deleted. For details on the operating procedures, refer to the following manual.

Operation of event history
Removal of the SD memory card
When the memory initialization event occurs, the event history is stored in the internal memory. If the internal memory
reaches the maximum allowable number for saving event history, all subsequent events will be dropped.
Insertion of an SD memory card
The event history, which have been stored in the internal memory during absence of the SD memory card, is stored to
the SD memory card. If the re-inserted SD memory card contains an event history file of the same file size, the C
Controller module continues to store the event history information. If the file size is different, the C Controller module
removes the existing event history file and creates a new event history file.
