Auto Logging

When inserting an SD memory card, which holds data logging setting, into the CPU module, the data logging automatically
starts based on the data logging setting information on the SD memory card.
How to use auto logging
This section describes how to use auto logging.
1.
Prepare an SD memory card that contains data logging settings as well as common settings (auto logging common
settings) in which auto logging is enabled.
2.
Insert the SD memory card prepared in step 1 into the CPU module while it is running.
3.
When the SD memory card is inserted, data logging starts automatically. (CARD READY LED and CARD ACCESS LED
turn on.)
4.
Check that auto logging is completed on the engineering tool or using the LED
5.
Remove the SD memory card.
*1 When "Data Logging Function" is set in the LED indicator setting, the FUNCTION LED flashes every 200ms. If the executed function
has higher priority of the FUNCTION LED than the function set in the LED indicator setting, the data logging function status is not
displayed. ( Page 131 LED display setting)
• Even when the data logging stop operation is performed after auto logging starts, auto logging does not end
until when the SD memory card is removed.
• To use auto logging, the auto logging common setting file and data logging setting file for operation are
required in the SD memory card.
• Write the auto logging common setting file to the SD memory card only when using auto logging. When auto
logging is not used, delete the auto logging common setting file. (Page 986 Writing the logging setting,
Page 987 Deleting the logging setting)
Auto logging start conditions
Auto logging starts in the following cases.
■Inserting the SD memory card with the auto logging setting while the CPU module is running
Auto logging starts when the SD memory card with the auto logging setting is inserted while the CPU module is running.
(When the CPU module is in the STOP state, auto logging starts by changing the state from STOP to RUN.)
If data logging is in progress before the SD memory card with the auto logging setting is inserted, auto logging does not start.
■Inserting the SD memory card with the auto logging setting while the CPU module is off or
being reset, and powering on or resetting the CPU module
Auto logging starts when the CPU module is powered on or reset after the SD memory card with the auto logging setting is
inserted while it is off or being reset. If data logging is in progress, powering on or resetting the CPU module executes auto
logging instead of the data logging.
Conditions for auto logging completion
Auto logging completes when a completion condition is met as described in the following table. These completion conditions
can also be configured in combination with each other. When they are configured in combination, auto logging completes as
soon as one of the conditions is met.
