Logging hold request
A hold trigger is generated from a program at any timing.
After ON (1) is set to 'CH1 Logging hold request' (Un\G471), a preset number of data is collected and then the logging stops.
'CH1 Logging hold request'
CH1 Logging data
(Un\G10000 to Un\G19999)
The data before the last 10000 points
• The following delay time occurs until multiple input module receives a hold trigger after the value in 'CH1
Logging hold request' (Un\G471) is changed from 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 changed from ON (1)OFF (0) before 'CH1 Logging hold
flag' (Un\G409) turns to ON (1), the number of data set in 'CH1 Post-trigger logging points' (Un\G539) is
collected, and then logging resumes soon, without stopping.
• If a value other than OFF (0) and ON (1) is set to 'CH1 Logging hold request' (Un\G471), an error occurs. A
logging hold request range error (error code: 1D7H) is stored in 'Latest error code' (Un\G0), and 'Error
flag' (Un\G69, b15) and the ERROR LED turn on.
■Checking that the logging has stopped
Check that 'CH1 Logging hold flag' (Un\G409) is ON (1).
Controlled by the multiple input module
'CH1 Number of logging data' (Un\G436)
A hold trigger is generated.
The logging is held.
