Mitsubishi Electric MELSEC iQ-R Series User Manual page 251

Symptom
The report file was not created. (The
report creation trigger was not detected)
Unable to output the number of records
worth of data to a report.
Data separation occurs.
Unable to display the CSV formatted data
logging and event logging time/date
information correctly.
The information of milliseconds is not
displayed in the cells to which date and
time of the report file is output.
Unable to output the data correctly to the
report file.
Unable to start the "Layout setting"
screen.
The file cannot be downloaded from the
file browser.
Unable to end the layout settings.
Check point
Is the time of the satisfied condition longer than the
data sampling interval when a data condition is
specified?
Has the high speed data logger module's time been
changed by the time synchronization function?
Is the 'high speed sampling failure' (X1A) ON?
Is the 'processing overload occurrence' (X1B) ON?
Is the 'creation trigger reoccurrence' (X1D) ON?
Check the power supply status. (Has a momentary
power failure occurred?)
When the creation trigger occurred, was the specified
number of records worth of data saved to the data
logging file?
Is the creation trigger occurring immediately after
powering ON?
Was the data logging file, which includes the data at the
time the creation trigger occurred, deleted before
completing output to the report?
Is the number of device points less than the access
units? (MELSEC iQ-R High Speed Data Logger
Module User's Manual (Startup))
Is the report creation trigger set to synchronize with the
current value data?
Is general sampling being used?
Was the data changed after the report creation trigger
occurred?
Has the cell format been changed when the CSV file
was opened with Excel?
Was the cell format configured when the layout was
created?
Are the merged cells specified in the cell range where
the layout is set?
Are there data lines in the output source file of the data
logging layout?
Are the permissions granted to the user logged on to
Windows sufficient?
Are the permissions granted to the user logged on to
Windows sufficient?
For a file saved in the SD memory card inserted in a
high speed data logger module by using FTP
connection, check if the file is not directly opened 
closed in Excel.
Corrective action
• Adjust the system so that the time to satisfy the
creation trigger condition is longer than the data
sampling interval.
• Set the minimum synchronization timing required.
(Do not perform this while the system is in operation.)
(Page 132 Time synchronization setting)
• Decrease the number of the specified settings for
high speed sampling.
• Increase the data sampling interval of high speed
sampling.
• Set a constant scan to the CPU module. (Page
344 Processing Time)
• Correct the settings and lessen the processing load.
(Page 344 Processing Time)
• Adjust the system so that creation triggers do not
occur continuously. (Page 344 Processing Time)
• Correct the power supply status.
• Configure and adjust the system so that the creation
trigger occurs after the specified number of records
worth of data is saved in the data logging file.
(Page 72 Report output)
• Adjust the file switch timing for data logging.
• Set the number of device points sampled at one time
to less than the access units.
• Select "Synchronize creation trigger with current
value data." in the creation trigger settings.
(Page 207 Creation trigger)
• Use high speed sampling.
Data logging function: (Page 25 Sampling function)
Report function: (Page 74 Creation trigger and
current value data sampling)
• Configure the settings not to change the devices that
sample data as the current value of the report during
the period when the buffer memory report creation
execution information is ON.
• Monitor the value of report execution information in
the buffer memory so that the data does not change
until the report is created.
• Set the Excel cell format according to the arbitrary
date/time format for display.
• Set the Excel cell format according to the desired
date/time format for display. (Page 199 Data
logging layout, Page 206 Creation time layout)
• Split the merged cells.
• Do not specify merged cells in the cell range.
• Configure and adjust the system so that a creation
trigger occurs after data are output to the data
logging file which is the output source for the report.
• Log on as a user with a "standard" or higher access
authority.
• Log on as a user with a "standard" or higher access
authority.
• After selecting "Do not display" in "Window" in the
Excel menu, select "Display again."
