Recording monitor

The status of the recording function can be checked in the "Recording Monitor" screen of GX Works3.
For details, refer to the following:

Errors that occur when using the recording function

For details on the errors, refer to the following:
Note that errors for a CPU module do not occur when using the recording function.

Buffer memory used for the recording function

For the buffer memory used for the recording function, refer to the following:
Page 94 Buffer Memory

Considerations

The following shows the considerations when using the recording function.
Scan time extension
The scan time is extended while the recording function is running.
It is also affected by the size of data to be sampled, device address (number), type, and devices (buffer memory, link devices)
that access a module.
By default, the device/label batch specification is enabled, which means that more devices and labels are sampled and the
scan time is longer.
Saving a recording file
■If saving a file fails
If a file fails to be saved due to an insufficient free space on an SD memory card, an error occurs.
In addition, the following processing is performed according to the recording method.
• File saving trigger only: Data that failed to be saved is discarded, and data sampling and accumulation continue.
• Recording startup trigger + file saving trigger: Data that failed to be saved is discarded, and data accumulation is stopped
until the next recording startup trigger is satisfied.
The free space on an SD memory card is recommended to be checked before satisfying the condition of a file saving trigger.
■When switching a CPU module from RUN to STOP while saving a file
Processing continues until the file saving is completed.
When changing a recording setting before file saving is completed and switching a CPU module from STOP to RUN, the
changed setting will be enabled after the file saving is completed.
Whether the file saving is completed can be checked in 'Recording files saving completion' of a recorder module. (Page

■When stopping the operation of the recording function
When stopping the operation of the recording function in the "Recording Monitor" screen while saving a file, processing
continues until the file saving is completed.
If changing a recording setting before file saving is completed and restarting the operation of the recording function in the
"Recording Monitor" screen, the changed setting will be enabled after the file saving is completed.
Whether the file saving is completed can be checked in 'Recording files saving completion' of a recorder module. (Page
