[Set value] Offset from latest log block of log buffer [Default: 0000H]
- To read the latest log block, "0" is specified. To read the oldest log block used,
"Number of log blocks used – 1" is specified (see 387H below). This value
should be set such that the number of log blocks used is greater than or equal
to the log reading pointer + the number of log block being read. If anything else
is specified, the results will be unclear.
[Set value] No. of reading blocks [Default: 0000H]
- This specifies the number of blocks up to the old block to be read from the log
block reading point.
- A value of 14 or less should be set. If a value of 15 or higher is set, or if 0 is set,
14 blocks will be read.
[Stored value] Log buffer size available with the unit itself (number of log blocks)
[Set value: 0100H (256 blocks)]
- This is set by the unit itself when it boots.
[Stored value] Cumulative total of log blocks recorded after initialization
processing
- This is cleared to 0 when initialization processing is carried out.
- The number of logs is counted up to FFFFH (65535), but if an attempt is made
to record more logs than will fit into the available buffer space, logs are
overwritten, starting with the oldest.
- The number of logs will not be incremented past FFFFH (65535).
[Stored value] Current number of log blocks available for reading in log buffer
- This is cleared to 0 when initialization processing is carried out.
- The count of the number of logs used will not be incremented past the buffer
size.
