(9) Restarting logging
To restart logging, turn CH Logging hold request (Un\G1008 to Un\G1011) ON → OFF. Logging is restarted
from the head of the logging data storage area.
At this time, head pointer, trigger pointer, and the number of logging data are cleared, and CH Logging hold flag
(Un\G1016 to Un\G1019) turns off.
(a) Precautions
• It may take time for CH Logging hold flag (Un\G1016 to Un\G1019) to turn on after CH Logging hold
request (Un\G1008 to Un\G1011) is turned OFF → ON. To restart logging, turn CH Logging hold request
(Un\G1008 to Un\G1011) ON → OFF after confirming CH Logging hold flag (Un\G1016 to Un\G1019)
turns on.
• If CH Logging hold request (Un\G1008 to Un\G1011) is turned ON → OFF before CH Logging hold
flag (Un\G1016 to Un\G1019) turns on, logging does not stop.
(b) Each buffer memory when logging is restarted
When logging resumes, the value in each buffer memory area below is as follows.
*1 After logging is restarted, values are stored starting from the head buffer memory of the logging data storage area. Since
the value before logging is restarted is stored in CH Logging data (Un\G5000 to Un\G44999), check the valid data with
CH Number of logging data (Un\G1106 to Un\G1109) to refer to the logging data.
Buffer memory Value status
CH Head pointer (Un\G1090 to Un\G1093)
Values are initialized. (Initial value: 0)
CH Latest pointer (Un\G1098 to Un\G1101)
CH Number of logging data (Un\G1106 to Un\G1109)
CH Trigger pointer (Un\G1114 to Un\G1117)
CH Logging data (Un\G5000 to Un\G44999)
The value before logging is restarted is maintained.
