Functional description
• When i_bEN (execution command) is turned on, this FB stores the logging data stored in the file register in CSV format in
the SD memory card attached to the CPU module sequentially from the specified address of the file register (ZR) specified
in i_udDataAddr (start address of the storage location of logging data).
Ex.
The following shows an example of file register and CSV file content.
(1) i_udDataAddr (start address of the storage location of logging data): K10000
(2) i_uCHNum (number of channels): K2
(3) i_udSavePoints (number of save points): K10000

• Logging data is stored in increments of 500 points. When K1300 is specified for i_udSavePoints (number of save points),
logging data of 500 points is stored in an SD memory card first. Sequentially, data from 501 points to 1000 points is stored
and data from 1001 points to 1300 points is stored.
• Store logging data of each channel sequentially into the file register. Store signed word logging data into the file register.
• For the format of CSV files that this FB creates, refer to CSV File Output Format. ( Page 16 CSV File Output Format)
