Recording Function

This section shows the troubleshooting on the recording function.
Troubleshooting on starting the recording function
Symptom Check point
Unable to start the recording Is a recording setting for which the recording function starts
function. written?
Is a CPU module in the RUN state?
Are programs and parameters when configuring 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 118 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 118 Device/Label Sampling Setting, Page 94
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?
(Page 98 Recording buffer setting (recorder module),
Page 99 Recording buffer setting (camera recorder module))
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?)
(Page 118 Device/Label Sampling Setting)
Is a condition for a device, which is specified as a recording
startup trigger in a recording setting for which the recording
function starts, satisfied when selecting "Recording Startup
Trigger + File Saving Trigger" for "Recording Method" in the
saving period setting?
(Page 117 When selecting "Recording Startup Trigger +
File Saving Trigger" for "Recording Method", Page 25
Recording startup trigger)
Is a condition for a device, which is specified as a recording
startup trigger in a recording setting for which the recording
function starts, satisfied while the recording startup trigger is
enabled when selecting "Recording Startup Trigger + File
Saving Trigger" for "Recording Method" in the saving period
setting?
(Page 117 When selecting "Recording Startup Trigger +
File Saving Trigger" for "Recording Method", Page 25
Recording startup trigger)
Is a recorder module with a firmware version supporting the
function used in the following cases?
• Using a safety CPU
• Specifying a file server as the save destination for recording
files
(Page 307 Added and Changed Functions)
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.
• Check the mounted module.
• Review the program accessing an unmounted module.
• Satisfy the condition for the device.
• Satisfy the condition for the device.
■When using a safety CPU
• Update the module to a firmware version supporting a safety
CPU.
■When specifying a file server as the save destination for
recording files
• Change the save destination to an SD memory card.
• Update the module to a firmware version supporting saving
to a file server.
