List of the Errors That May Occur in Data Logging

If an error occurs in data logging, a diagnostic error will not be reported. Instead, the special relay (Data logging error)
turns on and a value indicating the cause of the error is stored in the special register (Data logging error cause).
If the data logging is stopped with an error, the logging can be restarted by using SM1938 (Data logging restart flag (at
logging stop with error)).
For information on "Registration" and "Cancel" in the "Timing of occurrence" column, refer to  Page 63, Section
6.4.
*1 This flag is supported by the QnUDVCPU and QnUDPVCPU with a serial number (first five digits) "17103" or later, or
LCPU modules (except for the L02SCPU and L02SCPU-P) with a serial number (first five digits) "17102" or later.
