1.1.2 Precautions on Using This Function

As an SD memory card is used for the logging function, there are risks of loss of data or data
damage depending on usage conditions. Consider possible risks, design a system and make
an evaluation of the system before using the function.
 Precautions when powering off the PLC
If the PLC is powered off during logging or accessing an SD memory card, the following
problems may occur.
• Data accumulated in the buffer memory are lost.
• Files may be damaged.
• The SD memory card may be damaged.
Take necessary measures such as the use of an uninterruptible power system (UPS) as
necessary.
 Logging speed and writing speed into an SD memory card
When the speed accumulating data is faster than the writing speed into an SD memory card,
data cannot be saved. Make an evaluation thoroughly before use.
