Logging hold request
A hold trigger is generated from a program at any timing.
Logging starts when ON (1) is set to 'CH1 Logging hold request' (Un\G471) and stops after a preset number of the data is
collected.
'CH1 Logging hold request'
(Un\G471)
CH1 Logging data
(Un\G10000 to Un\G19999)
The data before the last
10000 points are discarded.
• The following delay time occurs until an analog input module receives a hold trigger after the value in 'CH1
Logging hold request' (Un\G471) is turned OFF (0)  ON (1).
Trigger delay = Logging cycle (Cycle at which logging is actually performed) + Scan time of the CPU module
• When 'CH1 Logging hold request' (Un\G471) is turned ON (1)OFF (0) before 'CH1 Logging hold flag'
(Un\G409) turns to ON (1), the data set in 'CH1 Post-trigger logging points' (Un\G539) is not held after
logging, and logging resumes soon.
■Checking that the logging has stopped
Check that 'CH1 Logging hold flag' (Un\G409) is ON (1).
Controlled by the analog input module
OFF(0)
