Data logging function
The following is the list of special register areas relating to the data logging function.
No. Name Data stored Details Set by (setting
timing)
SD1210 Data logging setting No.1
Latest storage file number
Latest storage file
number
• The latest storage file number
• This register is cleared to 0 by the stop command from CPU
Module Logging Configuration Tool.
S (Status change)
SD1211
SD1212 Data logging setting No.1
Oldest storage file number
Oldest storage file
number
• The oldest storage file number
• This register is cleared to 0 by the stop command from CPU
Module Logging Configuration Tool.
S (Status change)
SD1213
SD1214 Data logging setting No.1
Internal buffer free space
Free space size of the
internal buffer (K bytes)
• The amount of free space of the internal buffer is stored in K
bytes. The smaller the value, the higher the generating ratio of
processing overflow.
• For the trigger logging, it refers to the total capacity of internal
buffer until the data for the number of records is collected after a
trigger occurred.
• This register is cleared to 0 by the stop command from CPU
Module Logging Configuration Tool.
S (Error)
SD1215 Data logging setting No.1
Number of processing
overflow occurrences
Number of processing
overflow occurrences
• The number of data logging processing overflow occurrences
• When overflow occurs, data is lost.
• When the count exceeds 65535, it returns to 0 and starts a new
cycle.
• With "Stop" set for the operation at the time when the number of
save files exceeds the limit, a processing overflow may occur
until the stop operation is completed after the collection of data
corresponding to the specified number of storage files was
completed.
• This register is cleared to 0 when the setting is registered or by
the stop command from CPU Module Logging Configuration
Tool.
S (Error)
SD1216 Data logging setting No.1
Data logging error cause
Data logging error
cause
Cause of the error generated during data logging operations is
stored.
0: No error
Other than 0: For details on the values stored when an error
occurs, refer to the list of error codes. ( Page 552 List of
Error Codes)
