(Un\G5000 to Un\G9999)
(6) Checking the stop of the logging
Check that CH Logging hold flag (Un\G1016 to Un\G1023) turns ON (1).
(7) Checking trigger detection time
The time at that the hold trigger was detected can be checked in the buffer memory.
Even when the logging cycle is set as less than 1s, the minimum time unit recorded in CH Trigger detection time
(Un\G1154 to Un\G1185) is second. Use trigger detection time as an indication to refer to the logging data.
*1 When the hold trigger is detected as soon as turning on the programmable controller, the CT input module may not
obtain the time in the CPU module. If the module could not obtain the time, the trigger detection time is recorded "0:0:0
on January 1st, 2000".
Trigger detection time is stored in the following buffer memory areas.
