Note
LOGO! 0BA7 provides a 1024-byte buffer for data logging. If the data in this buffer
reaches 512 bytes, LOGO! automatically writes data to the SD card inserted in the SD
card slot. If the speed of data generation in LOGO! 0BA7 is faster than that of data write
to the SD card, data loss may occur. To avoid the occurrence of data loss, apply an
enable signal to the data log function block at a minimum time interval of 500 ms.
A data log file on the SD card can store a maximum of 2,000 records.
Only the most recent data log file on the SD card can be uploaded from LOGO! to
LOGO!Soft Comfort.
Under the following three circumstances, LOGO! creates a new data log file:
•
When LOGO! has downloaded a circuit program configured with the data log function
from LOGO!Soft Comfort
•
When the data log file in LOGO! is not properly closed at the time LOGO! in RUN
mode is powered off
•
When your edits to the circuit program in LOGO! influence the data log configuration
made in LOGO!Soft Comfort
