File saving trigger
A file saving trigger is used to specify when to save accumulated data, and satisfied at any of the following timings.
(Page 38 Recording buffer, Page 40 Operating status)
*1 Whether a trigger has been satisfied is determined during the END processing in a scan of a CPU module.
When a file saving trigger is satisfied in multiple recording settings, data is saved in order from a setting that can be saved.
*1
• A specified device rises or falls.
• A specified buffer memory
• A specified time elapses after completion of data accumulation
• A file is saved in the "Recording Monitor" screen. (Page 65 RECORDING MONITOR)
*1 For the devices that can be specified, refer to the following:
Page 29 Devices that can be specified as triggers
*2 A trigger is satisfied by setting a device and condition in the file saving trigger setting and when the set condition is satisfied. (Page
61 File Saving Trigger Setting)
Conditions can be set for multiple devices, and a condition number is added to each of them (up to 16 conditions can be set).
*3 A trigger is satisfied when each bit rises in the following buffer memories of a recorder module. (A condition number is added to each
bit.)

*4 Can be set only when selecting "Recording Startup Trigger + File Saving Trigger" for the recording method.
*5 The time accuracy of a recorder module affects a set timing and an actual one, causing an error between them. For the time accuracy,
refer to the following:
MELSEC iQ-R System Recorder User's Manual (Startup)
Establishment of a trigger condition is registered as an event, and its timing can be checked when reproducing
data on the offline monitor.
Completion of saving a recording file is also registered as an event, but an event history is not output to the
saved recording file.
Precautions
Start the recording function and check that its operating status switches to 'operating,' then satisfy a file saving trigger if data is
accumulated in the recording buffer. The operating status can be checked in 'In recording operation' of a recorder module.
