Appendix 4 Buffer Memory Areas
CH1 Trigger pointer
In CH1 Logging data (Un\G10000 to Un\G19999), the buffer memory address where the data at the time of a hold trigger
event is stored can be checked.
The difference between the buffer memory address where the data at the time of a hold trigger event is stored and the start
address in CH1 Logging data (Un\G10000 to Un\G19999) is stored.
For details on the logging function, refer to the following.

Buffer memory address
The following shows the buffer memory address of this area.
When 'CH1 Logging hold request' (Un\G471) is turned on → off, 'CH1 Trigger pointer' (Un\G437) is cleared to
0.
CH1 Logging cycle monitor value
This area stores the actual logging cycle which is calculated from the refreshing cycle of data to be logged.
When 'Operating condition setting request' (Un\G70, b9) is turned off
→
on
→
off, the actual logging cycle is stored in Logging
cycle monitor value in the corresponding channel where the logging function is enabled.
For details on the logging function, refer to the following.

The following values are stored in 'CH1 Logging cycle monitor value' (Un\G441 to Un\G442).
