Logging Hold Request - Mitsubishi Electric MELSEC iQ-R Series User Manual

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'
(Un\G471)
CH1 Logging data
(Un\G10000 to Un\G10999)
The data before the last 1000 points
are discarded.
• The following delay time occurs until a temperature input module receives a hold trigger after the value in
'CH1 Logging hold request' (Un\G471) is changed from OFF (0) to 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) to 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: 1D7H) is stored in 'Latest error code' (Un\G0), 'Error flag'
(XF) and the ERR LED turn on.
Checking that the logging has stopped
Check that 'CH1 Logging hold flag' (Un\G409) is ON (1).
