The following shows the buffer memory address of this area.
■
Operation of the logging hold processing
• When Disable (0) is set to 'CH1 Level trigger condition setting' (Un\G540), the logging hold processing starts by turning
off → on 'CH1 Logging hold request' (Un\G471).
• When a value other than Disable (0) is set to 'CH1 Level trigger condition setting' (Un\G540), the logging hold processing
starts after 'CH1 Logging hold request' (Un\G471) is turned off
→
on and the set level trigger condition is satisfied. When the
level trigger is enabled, use this buffer memory area as an interlock condition to operate the level trigger.
• If 'CH1 Logging hold request' (Un\G471) is turned on
→
off during the logging hold processing, the hold (stop) status is
cleared and the logging restarts.
■ Default value
The default value is off (0).
The stop status of the logging can be checked with 'CH1 Logging hold flag' (Un\G409).
