■Resetting the timeout time
The timeout time is reset at the following timings:
• The value in a specified device changes.
• The operating status switches to 'stopped' or 'preparing.'
• The value in 'Timeout detection of file saving trigger' (Un\G4008) is changed from 'enabled' to 'disabled.'
■Timing when a change in a device is ignored
Even if the value in a specified device changes within a timeout time, a file saving trigger may be satisfied by timeout
detection.
During a period from the END processing immediately before a timeout time elapses to the timeout time, a file saving trigger
is satisfied by timeout detection even if the value in a specified device changes.
The following shows the flow.

(3) A file saving trigger is satisfied.
(4) Period during which a file saving trigger is satisfied even if the value in a specified device changes
(5) A specified device value changes.
(6) Program operation
(7) END processing

(9) Whether a specified device value changes is determined.
(10) Specified device value
■Timing when the value 'disabled' in 'Timeout detection of file saving trigger' (Un\G4008) is
ignored
If there are two types of timings in one scan: when the value in 'Timeout detection of file saving trigger' (Un\G4008) changes
to 'disabled' and when a timeout is detected, a file saving trigger may be satisfied even when changing the value before the
trigger is satisfied.
The following shows a timing to determine which value, 'enabled' or 'disabled,' is stored in 'Timeout detection of file saving
trigger' (Un\G4008).
