3. D2 (destination 2): Execution Status
D2 specifies the first data register of the data registers to use in DLOG instruction.
Starting from the specified data register, 2 continuous words of data registers are used. Specify the first data register so that the
range of data registers is not exceeded.
Storage Destination
Starting number+0
Starting number+1
*1 Stores the value calculated from the file size. The decimal part is rounded up.
Example: When D2 is "D0000", the file size set for external memory device is "5 MB (5120 KB)", and the CSV file is "520 KB",
File size ratio = 520 / 5120 × 100 = 10.2 → 11
"11" is stored in the register.
*2 For how to set the file size for external memory devices, see Chapter 5 "Functions and Settings" in the "FC6A Series MICROSmart User's
Manual".
Execution Status
Specify the device to store the status code. One of the following status codes is stored according to the DLOG instruction
execution status and result.

—
The SD memory card is not inserted
The SD memory card is full
Writing log data to the SD memory card fails
The CSV file has exceeded the upper limit of the log data size
The SD memory card is write protected
DLOG instruction is executed while another DLOG instruction or TRACE instruction
is being executed
Converting log data to numeric characters fails
Creating the folder fails
Opening the CSV file fails
Writing log data to SD memory card is in progress

—
The SD memory card is full
Writing log data to the SD memory card fails
The number of CSV files in one folder for one day has exceeded 99 files
(YYYYMMDD_01.csv to YYYYMMDD_99.csv)
The SD memory card is write protected
DLOG instruction is executed while another DLOG instruction or TRACE instruction
is being executed
Converting log data to numeric characters fails
Creating the folder fails
Opening the CSV file fails
Because SD memory card is not inserted, log data is stored in Plus CPU module
RAM. If the power to the PLC is turned off without inserting SD memory card, all
logged data are cleared. When SD memory card is not inserted and the log data
exceeds 1 MB, "11. RAM overflow" occurs.
The total amount of log data exceeds 1MB while SD memory card is not inserted
The data register for storing the path exceeds the largest data register (D7999,
D61999, D269999)
The logging data is not saved because the CSV file exceeded the file size set by the
external memory device in advanced mode
Writing log data to SD memory card is in progress
