Data stored Details
Latest storage file • The latest storage file number
number • This register is cleared to 0 by the stop command from CPU
Module Logging Configuration Tool.
Oldest storage file • The oldest storage file number
number • This register is cleared to 0 by the stop command from CPU
Module Logging Configuration Tool.
Free space size of the • The amount of free space of the internal buffer is stored in K
internal buffer (K bytes) 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.
Number of processing • The number of data logging processing overflow occurrences
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.
Data logging error Cause of the error generated during data logging operations is
cause 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)
