SD Memory Card

This section describes how to save log data to the SD memory card and maintain the SD memory card.
The 40- and 48-I/O types SmartAXIS are equipped with an SD memory card slot, and SD memory cards with 32GB maximum
capacity can be used. Device values (log data) can be output to the SD memory card as CSV files using the DLOG (data log) and
the TRACE (data trace) instructions/FB. This enables log saved and analyzed when problems occur. The contents of the files saved
to the SD memory card can be checked on a computer. The files saved to the SD memory card can be uploaded using WindLDR.

For the SD memory card hardware specifications, see "Product Specifications" on page 2-1.
Notes:
Set the write-protect switch on the SD memory card to the off position before inserting it.

Insert and remove the SD memory card in the direction indicated on the SmartAXIS module.

Do not remove the SD memory card while it is being accessed. There is a risk of damage to the SD memory card and the data stored on it.

Save Log Data
Using the DLOG (data log) and the TRACE (data trace) instructions/FB, specified device values are saved to the SD memory card
as the log data (CSV files). The DLOG instruction/FB outputs the date and time and the device values of the specified devices to
the CSV file in the specified folder. The TRACE instruction/FB outputs the date and time and the device values of the previous
number of scans for the specified devices to the CSV file in the specified folder. For details on the DLOG and TRACE instructions,
see Chapter 26 "Data Log Instructions" in the SmartAXIS Ladder Programming Manual. For details on the DLOG and TRACE FB,
see Chapter 16 "The data logging FB" in the SmartAXIS FBD Programming Manual.
The SmartAXIS cannot write data to the SD memory card when its write-protect switch is on. Always set the write-protect switch
of the SD memory card to off position before inserting it to the SmartAXIS.
