Other Functions
This section describes some useful functions available in addition to the basic features of the data logging function.
Setting the operation at the time of transition to RUN
This function configures the operation of data logging that occurs when the user performs the following operations (transition
to RUN) after the data logging setting are registered. (Page 468 Logging operation)
• Turning off and on the CPU module and switching to the RUN mode
• Resetting and running the CPU module
• Stopping and running the CPU module
The operation at the time of transition to RUN can be set individually for each setting number (1 to 4).
Operation at the time of transition to RUN
The operation at the time of transition to RUN can be set to either of the following:
■Auto start
After the user performs one of the operations listed above, data logging automatically starts when the operating status of the
CPU module changes from STOP to RUN.
To first start data logging, the user must instruct the CPU Module Logging Configuration Tool to start data
logging.
■Start by user operation
After the user performs one of the operations listed above, the data logging state is switched to "Waiting start Not collected"
when the operating status of the CPU module changes from STOP to RUN. To start data logging again, the user must instruct
the CPU Module Logging Configuration Tool to start data logging.
Data logging operation that occurs after operating status of CPU module has changed
Data logging does not continue when the operating state of the CPU module changes from RUN to STOP or PAUSE after it
has been started. The data logging state changes to "Waiting RUN Not collected" and data collection is stopped.
SD memory card replacement
SD memory cards can be replaced using the SD memory card forced disable function even while data logging is in progress.
(Page 122 SD Memory Card Forced Stop) This function works by disabling data writes to the SD memory card while
allowing data collection to continue. (Data collection continues in accordance with the settings registered when data logging is
started.)
If SD memory card replacement causes processing overflow, make adjustments by changing the collection
interval, internal buffer capacity, or other settings.
