Is a CPU module in the RUN state?
Are programs and parameters when setting a recording
setting written to a CPU module?
Are devices and labels that do not exist in the CPU parameter
and modules that are not mounted specified in the device/
label sampling setting in the recording setting?
(Page 56 Device/Label Sampling Setting)
Does the sampling size of a recording setting (total size of
devices and labels specified in the device/label sampling
setting) exceed the capacity of the buffer area for data
sampling in the CPU parameter?
(Page 56 Device/Label Sampling Setting, Page 48 Buffer
area setting for data sampling)
Is the buffer capacity of a recording setting for which the
recording function starts set in the recording buffer setting in
the module parameter (recorder module)?
(Page 51 Recording buffer setting)
Does a program run properly when the device/label batch
specification is enabled in the device/label sampling setting in
the recording setting? (Is a program accessing an unmounted
module running?)

Corrective action
• Write a recording setting for which the recording function
starts.
• Switch the CPU module to the RUN state.
• Write the programs and parameters to the CPU module.
• Review the recording setting.
• Review the recording setting.
• Review the buffer area setting for data sampling in the CPU
parameter.
• Review the recording buffer setting in the module parameter
(recorder module).
• Check the mounted module.
• Review the program accessing an unmounted module.
• Satisfy the condition of the device.
• Satisfy the condition of the device.
• Wait for a recording file to be saved.
