■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
and on 'CH1 Logging hold request' (Un\G471).
• When a value other than Disable (0) is set to 'CH1 Hold trigger condition setting' (Un\G540), the logging hold processing
starts after 'CH1 Logging hold request' (Un\G471) is turned off and on and the set 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 and off during the logging hold processing, the hold (stop) status is
cleared and the logging restarts.
■Default value
The default value is OFF (0) for all the channels.
The stop status of the logging can be checked with 'CH1 Logging hold flag' (Un\G409).
